Powersafe L1 Powerlock Connector

Phase 3 Powersafe single pole devices are the highest rated, safest and finest quality powerlock type connectors as used for power distribution, aerospace, events, military and manufacturers. Powersafe inline connectors easily terminate to copper cable using set-screw contacts. Secure coupling of the plugs, connectors and receptacles is achieved through an innovative mechanical locking system that disengages with a simple release key.

Amperage & Cable Size Explained

Powersafe Connectors are available in either Male (source) or Female (drain) format as 800A or 500A. Device amperage is determined by cable size #4 SC – 600 MCM (25mm² – 185mm²) power cable requires 500A connectors. 500 MCM-600MCM (240mm2 – 300mm2) power cable requires 800A connectors.

Please note, if you require Powersafe for cable sizes #4 SC to 3/0, you must purchase a reducer kit separately.
