Despite being a permanent panel-mount connector, PFPS-3Y retains the PowerFit key-release mechanism, allowing field technicians to disconnect mating Line Drain connectors without tools. IP2X finger protection and a plastic end cap protect the contacts when no mating connector is present. The Panel Source has a 55.3mm flange width and 50.7mm total depth, with a 42.5mm body diameter. It is shallower than the Panel Drain, requiring less clearance behind the panel.\"}}]}\u003c\/script\u003e\n\u003csection class=\"kupo-download-section\" data-product-id=\"PFPS-3Y\"\u003e\n  \u003ch2\u003eDownload\u003c\/h2\u003e\n  \u003ca class=\"kupo-download-link\" href=\"https:\/\/pub-87314d729f334121b80f91e16c4e7f60.r2.dev\/PFPS-3Y.pdf\" target=\"_blank\" rel=\"noopener\" download\u003e\n    Download Spec Sheet (PDF)\n  \u003c\/a\u003e\n\u003c\/section\u003e","brand":"KUPO Power","offers":[{"title":"PowerFit Single Pole (IP67) \/ 400A \/ Panel Mount Receptacle","offer_id":68067491086556,"sku":"PFPS-3Y","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/3491\/5548\/files\/PFPS-3Y.jpg?v=1793858520","url":"https:\/\/kupopower.com\/products\/pfps-3y","provider":"KUPO Power","version":"1.0","type":"link"}
