Powersafe Single Pole Connector

Phase 3’s Powersafe single pole connectors are the highest rated, safest and finest quality powerlock connectors as used by the power distribution, events, military and cable assembly industries worldwide. Powersafe connectors are available as inline plugs and panel mount sockets that easily terminate to low voltage copper power cables (i.e H07RN-F) using industry standard crimp tools or set-screw contacts. Termination to aluminium cable is also possible with our bimetallic contacts.

Secure coupling of plug and socket is achieved through an innovative mechanical locking system that disengages with a simple release key. The industrial plug’s powerlock mating system means Powersafe cannot be mismated or disconnected accidentally under load.

Phase 3’s electrical connectors are 100% manufactured and assembled in the UK to ISO 9001:2015 quality standards. All Powersafe products are available with full UL, CE and VDE certifications. The electrical power connectors can be used for high current connections up to 800 amps in single or three phase electrical applications.

Innovative Design

Our engineers designed a unique, durable and high performing contact band that makes Powersafe the industry’s elite single pole plug. Phase 3’s contact band has 29 transfer bridges allowing for a higher 800A rating. The contact band has a one-piece, symmetrical design with offset fingers, meaning the band does not come out or overheat.

Exceptional Quality

Phase 3 use only the finest quality materials sourced from Europe or America. Powersafe is manufactured from 99.9% pure, highly conductive copper; no Tellurium is used meaning the metalwork is incredibly durable. Customers prefer our heavy-duty insulator as they are moulded with flame retardant plastics (UL94); no fibre glass is used therefore the product does not crack easily when handling.

Manufacturing Excellence

All Powersafe products are manufactured and assembled in the UK by our team who have over 35 years experience. We manufacture to ISO:9001:2015 Standard with UL Certified single pole connectors available. The 500A & 800A industrial plugs come with a hand grip as standard, but we go the extra mile and offer a moulding customisation option with your brand colours and logo on.
