Product Description
The PFLS-3GY-C300-400-M40-M50 is an 800A PowerFit single-pole line source connector for high-current temporary and permanent power distribution. Its gray housing identifies Line 3 (L3), while the crimp (for 400mm2 cable) termination supports heavy cable or busbar-style integration depending on the connector format. Silver-plated copper contacts, high-impact thermoplastic insulation, IP67 protection when mated, and UL94-V0 body material make the connector suitable for demanding event, industrial, energy storage, and generator distribution environments.
Key Features
- Innovative key-release pin allows for fast and convenient disconnection
- Copper contact with silver plating ensures excellent conductivity
- Ergonomic rubber grip enhances handling comfort and safety
- Durable thermoplastic body offers superior impact resistance and electrical insulation
- M40*1.5 cable gland with rubber bushing for secure IP67-rated sealing
Certifications & Standards
- TÜV certification listed on source spec sheet
- CE marking for European market compliance
- RoHS compliance restricts hazardous substances
- REACH compliance supports material traceability
- UL94-V0 flame rating for the connector body material
Applications
The PFLS-3GY-C300-400-M40-M50 supports high-current power distribution where single-pole connectors must remain easy to identify, quick to mate, and protected against demanding site conditions. Typical uses include event power distribution, generator rental, industrial switchgear, battery energy storage systems, and other professional power systems that require durable 800A connectors.
Compatibility
This connector belongs to the KUPO PowerFit single-pole connector family. The push-and-twist interface, colour-coded housing, and listed electrical ratings make it suitable for PowerFit system layouts where mating connector type, conductor role, and project wiring convention are confirmed before installation.

Frequently Asked Questions
What is the PFLS-3GY-C300-400-M40-M50 and what role does it play in a PowerFit system?
PFLS-3GY-C300-400-M40-M50 is a KUPO PowerFit 800A line source connector with a gray housing for Line 3 (L3). As an inline source-side connector, it forms part of a single-pole high-current connection and is designed for IP67 protection when mated.
How much current and voltage can PFLS-3GY-C300-400-M40-M50 handle?
PFLS-3GY-C300-400-M40-M50 is rated for 800A Maximum. The voltage rating is 1000V AC/DC Maximum, with a 4500V AC test voltage, insulation resistance greater than 5000 megohms at 500V AC, and contact resistance of 0.1 milliohms.
What does the gray housing on PFLS-3GY-C300-400-M40-M50 identify?
The gray housing identifies Line 3 (L3). The source spec sheet associates this colour with regional phase colour, so the colour should be checked against the project's wiring convention before installation.
How is PFLS-3GY-C300-400-M40-M50 terminated and operated?
PFLS-3GY-C300-400-M40-M50 uses crimp (for 400mm2 cable) contact termination and a push-and-twist with key release mechanism connection interface. The key-release pin supports fast and controlled disconnection.
What certifications and environmental protections are listed for PFLS-3GY-C300-400-M40-M50?
The spec sheet lists TÜV, CE, RoHS, and REACH compliance, IP67 rating while mated, UL94-V0 flammability rating for the body material, and a working temperature range of -25 to 125 degrees Celsius.
