Why Certification Matters
If your terminals aren’t certified to BS EN 61238-1:2003, the trusted standard for copper connectors, there’s no guarantee they’ll perform under heat, load, or fault conditions.
That puts your project, your team, and even your insurance at risk.

TQ™ Certified Terminals + SWA Calibrated Tools = SWA Approved System
When used with our calibrated crimping tools and control-issue dies, TQ™ terminals form an SWA-approved termination system, which has been tested by us for total performance and reliability.
It’s not just DEKRA-certified components - it’s a complete, consistent solution you can trust.
