As the source side of an inline cable connection, it features the innovative patent key-release pin that enables tool-free disconnection. The push-and-twist mechanism secures the connection during operation while allowing rapid uncoupling when needed. It is commonly deployed in outdoor music festival applications.

The maximum voltage rating is 1000V AC or 1500V DC. The silver-plated brass contact achieves a contact resistance of just 0.1 milliohms, significantly reducing resistive heating compared to plain brass contacts at sustained high-current loads. This low resistance is particularly important for L1 circuits carrying continuous phase current.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003cdiv class=\"kupo-faq-seo-item\"\u003e\n \u003ch3\u003eWhy choose the black L1 variant (PFLS-1BK-S120M40A) for your installation?\u003c\/h3\u003e\n \u003cp\u003eUnder North American NEC conventions, black identifies the first line conductor (L1) in a three-phase system. It is the default phase conductor for single-phase 120V branch circuits and the standard L1 in three-phase configurations alongside red (L2) and blue (L3). Black L1 conductors carry the bulk of single-phase loads in commercial and industrial settings. On the Line Source connector, the black housing wraps the 170mm body including the area around the key-release mechanism. This means the phase is identifiable even during the push-and-twist connection process, reducing the chance of connecting to the wrong L1 circuit. Because black appears in multiple phase conventions worldwide, the PowerFit phase-encoded SKU system (1BK vs 2BK vs NBK) prevents dangerous cross-convention mix-ups.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003cdiv class=\"kupo-faq-seo-item\"\u003e\n \u003ch3\u003eWhat safety certifications apply to PFLS-1BK-S120M40A?\u003c\/h3\u003e\n \u003cp\u003ePFLS-1BK-S120M40A is TUV Rheinland certified (ID 1111303479) under Type Approval, Safety, and Regular Production Surveillance categories.

The housing material achieves a UL94-V0 flammability rating, which is the highest classification for vertical flame resistance in plastics, meaning the material self-extinguishes within 10 seconds with no flaming drips.

Never reuse cotter pins.\"}}]}\u003c\/script\u003e\n\u003csection class=\"kupo-download-section\" data-product-id=\"PFLS-1R-S120M40A\"\u003e\n \u003ch2\u003eDownload\u003c\/h2\u003e\n \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/PFLS-1R-S120M40A.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e\n Download PFLS-1R-S120M40A Spec Sheet (PDF)\n \u003c\/a\u003e\n\u003c\/section\u003e","brand":"KUPO Power","offers":[{"title":"PowerFit Single Pole (IP67) \/ 400A \/ Inline Connector","offer_id":50208843268316,"sku":"PFLS-1R-S120M40A","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/3491\/5548\/files\/PFLS-1R-S120M40A-b.jpg?v=1777364440"},{"product_id":"pfls-1bn","title":"PFLS-1BN-S120M40A - PowerFit 400A Source Line Connector, Brown (L1)","description":"\u003c!-- Combined Shopify product HTML for PFLS-1BN-S120M40A --\u003e\n\u003cstyle\u003e\n.kupo-section-title {\n margin: 1.25rem 0 1rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.3;\n color: #005F96 !important;\n letter-spacing: 0;\n}\n.product-description h3 {\n color: #005F96 !important;\n font-size: 18px !important;\n font-weight: bold;\n margin-top: 1.5rem;\n margin-bottom: 0.75rem;\n line-height: 1.35;\n letter-spacing: 0;\n}\n.product-description,\n.product-description p,\n.product-description li {\n color: #222222 !important;\n}\n.kupo-faq-seo-block {\n margin: 3rem 0 0 0;\n padding: 0;\n border: 0;\n background: transparent;\n box-sizing: border-box;\n}\n.kupo-faq-seo-block h2 {\n margin: 0 0 1.6rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.4;\n color: #005F96 !important;\n}\n.kupo-faq-seo-item h3 {\n margin: 0 0 0.35rem 0;\n font-size: 17px !important;\n font-weight: 600;\n line-height: 1.45;\n color: #005F96 !important;\n}\n.kupo-faq-seo-item p {\n margin: 0;\n line-height: 1.6;\n color: #222222 !important;\n}\n.kupo-download-section {\n margin: 2rem 0 0 0;\n padding: 0;\n border: 0;\n background: transparent;\n box-sizing: border-box;\n}\n.kupo-download-section h2 {\n margin: 0 0 1rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.4;\n color: #005F96 !important;\n}\n.kupo-download-link {\n display: inline-flex;\n align-items: center;\n gap: 0.4rem;\n font-size: 16px !important;\n line-height: 1.5;\n color: #111111 !important;\n font-weight: 600;\n text-decoration: underline;\n}\n\u003c\/style\u003e\n\u003csection class=\"product-description\" data-sku=\"PFLS-1BN-S120M40A\"\u003e\n \u003ch2 class=\"kupo-section-title\"\u003eProduct Description\u003c\/h2\u003e\n\u003c!-- PowerFit 400A Line Source Connector (Brown) | PFLS-1BN-S120M40A | 2026-03-23 --\u003e\n\n\u003cdiv class=\"product-description\" data-sku=\"PFLS-1BN-S120M40A\" data-color=\"Brown\"\u003e\n\n \u003cdiv class=\"product-overview\"\u003e\n \u003cp\u003eThe PFLS-1BN-S120M40A brings intelligent European-standard design to high-current power distribution across the IEC region. Brown L1 phase marking ensures seamless integration with continental venue infrastructure and rental networks that operate under strict electrical compliance codes. What truly distinguishes this Line Source connector is its patent-pending key-release pin - a smart mechanical innovation that replaces the traditional tool-assisted uncoupling approach, reducing setup complexity and handler fatigue on multi-day installations. Combining a male contact with push-and-twist geometry, 400A\/660A dual-rating, and IP67 environmental sealing, the PFLS-1BN-S120M40A delivers the reliability and efficiency demanded by European touring productions and permanent installation networks.\u003c\/p\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"product-features\"\u003e\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary Key-Release Pin:\u003c\/strong\u003e Patent-pending mechanism replaces tool-dependent uncoupling with a simple push-and-twist motion, reducing handler training requirements and setup errors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIEC Phase Compliance:\u003c\/strong\u003e Brown L1 marking aligns with European electrical standards (BS 1363, CEE 7\/16 derivatives) and meets regional venue expectations across EU, UK (new standard), and associated markets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMale Contact Architecture:\u003c\/strong\u003e Carefully engineered contact geometry pairs with the line source connection protocol for reliable mating across thousands of cycle operations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision-Engineered Sealing:\u003c\/strong\u003e M40 x 1.5 cable gland with dual-component (nylon\/rubber) bushing achieves IP67 rating without compromising quick-coupling ease\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrass Silver-Plated Conductivity:\u003c\/strong\u003e Superior contact resistance (0.1 milliohms) and oxidation resistance ensure consistent power delivery on extended touring and festival circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermoplastic Housing Durability:\u003c\/strong\u003e High-impact-resistant, non-conductive material rated UL94-V0 provides both physical and electrical safety in professional venues\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eErgonomic Handling:\u003c\/strong\u003e Textured rubber grip improves comfort during extended use and gloved operation\u003c\/li\u003e\n\u003c\/ul\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"product-certifications\"\u003e\n \u003ch3\u003eCertifications \u0026amp;

The M40 cable gland accommodates cables through two included rubber bushings (inner diameter 23mm and 33mm), and the R120 reduction sleeve (brass with silver plating) handles conductor diameters up to 16.50mm.

The push-and-twist mechanism secures the connection during operation while allowing rapid uncoupling when needed. It is commonly deployed in industrial manufacturing plant applications.

Never reuse cotter pins.\"}}]}\u003c\/script\u003e\n\u003csection class=\"kupo-download-section\" data-product-id=\"PFLS-2W-S120M40A\"\u003e\n \u003ch2\u003eDownload\u003c\/h2\u003e\n \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/PFLS-2W-S120M40A.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e\n Download PFLS-2W-S120M40A Spec Sheet (PDF)\n \u003c\/a\u003e\n\u003c\/section\u003e","brand":"KUPO Power","offers":[{"title":"PowerFit Single Pole (IP67) \/ 400A \/ Inline Connector","offer_id":50208843628764,"sku":"PFLS-2W-S120M40A","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/3491\/5548\/files\/PFLS-2W-S120M40A-b.jpg?v=1777364447"},{"product_id":"pfls-2y","title":"PFLS-2Y-S120M40A - PowerFit 400A Source Line Connector, Yellow (L2)","description":"\u003c!-- Combined Shopify product HTML for PFLS-2Y-S120M40A --\u003e\n\u003cstyle\u003e\n.kupo-section-title {\n margin: 1.25rem 0 1rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.3;\n color: #005F96 !important;\n letter-spacing: 0;\n}\n.product-description h3 {\n color: #005F96 !important;\n font-size: 18px !important;\n font-weight: bold;\n margin-top: 1.5rem;\n margin-bottom: 0.75rem;\n line-height: 1.35;\n letter-spacing: 0;\n}\n.product-description,\n.product-description p,\n.product-description li {\n color: #222222 !important;\n}\n.kupo-faq-seo-block {\n margin: 3rem 0 0 0;\n padding: 0;\n border: 0;\n background: transparent;\n box-sizing: border-box;\n}\n.kupo-faq-seo-block h2 {\n margin: 0 0 1.6rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.4;\n color: #005F96 !important;\n}\n.kupo-faq-seo-item h3 {\n margin: 0 0 0.35rem 0;\n font-size: 17px !important;\n font-weight: 600;\n line-height: 1.45;\n color: #005F96 !important;\n}\n.kupo-faq-seo-item p {\n margin: 0;\n line-height: 1.6;\n color: #222222 !important;\n}\n.kupo-download-section {\n margin: 2rem 0 0 0;\n padding: 0;\n border: 0;\n background: transparent;\n box-sizing: border-box;\n}\n.kupo-download-section h2 {\n margin: 0 0 1rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.4;\n color: #005F96 !important;\n}\n.kupo-download-link {\n display: inline-flex;\n align-items: center;\n gap: 0.4rem;\n font-size: 16px !important;\n line-height: 1.5;\n color: #111111 !important;\n font-weight: 600;\n text-decoration: underline;\n}\n\u003c\/style\u003e\n\u003csection class=\"product-description\" data-sku=\"PFLS-2Y-S120M40A\"\u003e\n \u003ch2 class=\"kupo-section-title\"\u003eProduct Description\u003c\/h2\u003e\n\u003c!-- PowerFit 400A Line Source Connector (Yellow) | PFLS-2Y-S120M40A | 2026-03-23 --\u003e\n\n\u003cdiv class=\"product-description\" data-sku=\"PFLS-2Y-S120M40A\" data-color=\"Yellow\"\u003e\n\n \u003cdiv class=\"product-overview\"\u003e\n \u003cp\u003eThe PFLS-2Y-S120M40A bridges legacy UK electrical infrastructure with modern safety and performance.

Never reuse cotter pins.\"}}]}\u003c\/script\u003e\n\u003csection class=\"kupo-download-section\" data-product-id=\"PFLS-EGN-S120M40A\"\u003e\n \u003ch2\u003eDownload\u003c\/h2\u003e\n \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/PFLS-EGN-S120M40A.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e\n Download PFLS-EGN-S120M40A Spec Sheet (PDF)\n \u003c\/a\u003e\n\u003c\/section\u003e","brand":"KUPO Power","offers":[{"title":"PowerFit Single Pole (IP67) \/ 400A \/ Inline Connector","offer_id":50208843759836,"sku":"PFLS-EGN-S120M40A","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/3491\/5548\/files\/PFLS-EGN-S120M40A-b.jpg?v=1777364453"},{"product_id":"pfls-nbk","title":"PFLS-NBK-S120M40A - PowerFit 400A Source Line Connector, Black (N)","description":"\u003c!-- Combined Shopify product HTML for PFLS-NBK-S120M40A --\u003e\n\u003cstyle\u003e\n.kupo-section-title {\n margin: 1.25rem 0 1rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.3;\n color: #005F96 !important;\n letter-spacing: 0;\n}\n.product-description h3 {\n color: #005F96 !important;\n font-size: 18px !important;\n font-weight: bold;\n margin-top: 1.5rem;\n margin-bottom: 0.75rem;\n line-height: 1.35;\n letter-spacing: 0;\n}\n.product-description,\n.product-description p,\n.product-description li {\n color: #222222 !important;\n}\n.kupo-faq-seo-block {\n margin: 3rem 0 0 0;\n padding: 0;\n border: 0;\n background: transparent;\n box-sizing: border-box;\n}\n.kupo-faq-seo-block h2 {\n margin: 0 0 1.6rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.4;\n color: #005F96 !important;\n}\n.kupo-faq-seo-item h3 {\n margin: 0 0 0.35rem 0;\n font-size: 17px !important;\n font-weight: 600;\n line-height: 1.45;\n color: #005F96 !important;\n}\n.kupo-faq-seo-item p {\n margin: 0;\n line-height: 1.6;\n color: #222222 !important;\n}\n.kupo-download-section {\n margin: 2rem 0 0 0;\n padding: 0;\n border: 0;\n background: transparent;\n box-sizing: border-box;\n}\n.kupo-download-section h2 {\n margin: 0 0 1rem 0;\n font-size: 22px !important;\n font-weight: 700;\n line-height: 1.4;\n color: #005F96 !important;\n}\n.kupo-download-link {\n display: inline-flex;\n align-items: center;\n gap: 0.4rem;\n font-size: 16px !important;\n line-height: 1.5;\n color: #111111 !important;\n font-weight: 600;\n text-decoration: underline;\n}\n\u003c\/style\u003e\n\u003csection class=\"product-description\" data-sku=\"PFLS-NBK-S120M40A\"\u003e\n \u003ch2 class=\"kupo-section-title\"\u003eProduct Description\u003c\/h2\u003e\n\u003c!-- PowerFit 400A Line Source Connector (Black) | PFLS-NBK-S120M40A | 2026-03-23 --\u003e\n\n\u003cdiv class=\"product-description\" data-sku=\"PFLS-NBK-S120M40A\" data-color=\"Black\"\u003e\n\n \u003cdiv class=\"product-overview\"\u003e\n \u003cp\u003eThe PFLS-NBK-S120M40A is a 400A inline cable connector for neutral (N) distribution, delivering regional compliance for Australian (AS\/NZS 3000) and UK (old standard) electrical systems where black identifies the neutral return path. This Line Source connector houses the male contact and innovative patent key-release pin, enabling tool-free disconnection while maintaining a low-impedance neutral path.

This Line Source connector houses the male contact and innovative patent key-release pin, enabling tool-free disconnection while maintaining a low-impedance neutral return path. Engineered for North American power distribution systems where neutral is the reference point for grounding, voltage balance, and system safety.\u003c\/p\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"product-features\"\u003e\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eThe neutral function is foundational: it closes the circuit loops, balances voltage across all three phases, and provides the safety ground reference. Contact resistance below 0.1 milliohms and insulation integrity above 5000M Ohms ensure minimal voltage drop on the return path, protecting sensitive equipment and maintaining power quality across the distribution network.\u003c\/li\u003e\n \u003cli\u003eThe male contact and key-release mechanism enable rapid, tool-free mating and unmating. During maintenance windows, service calls, or load rebalancing, the neutral can be controlled connected and disconnected without disrupting voltage references or accidentally isolating circuits.\u003c\/li\u003e\n \u003cli\u003eThe source variant uses a shorter polyoxymethylene (POM) cotter pin optimized for cable-mounted operation. If pin inspection or replacement is needed, a small slotted screwdriver allows field disassembly without special tools, enabling rapid technician response during service and maintenance.\u003c\/li\u003e\n \u003cli\u003eRated for 400A continuous with 120mm² cable, scaling to 660A with 240mm² cable.
