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 molded with flame retardant plastics (UL94); no fiberglass 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 molding customization option with your brand colors and logo on.
