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.

3. Choose Your Connector Gender

Source & Drain Powerlock Connectors
Powersafe are available in Source (Male Contact / Female Insulator) & Drain (Female Contact / Male Insulator) format. Use the images on the right to help you distinguish between plug gender.
800A or 500A Connectors
Powersafe is rated at 500A – higher than the usual 440A single pole device. Powersafe devices are UL listed for use up to 455A. 500A connectors are available with Set Screw Termination for power cables up to 300 MCM (150mm CSA).
Powersafe also offers 800A connectors - higher than the standard 660A powerlock connectors. 800A industrial plugs are available with Crimp Termination for larger cable sections up to 600 MCM (300mm CSA). UL Listing is not available for these amperages.
