FAQ
Using non-certified terminals increases the risk of connection failure, overheating, and non-compliance with industry standards. Without third-party testing, performance claims can’t be verified — which can affect safety and even insurance validity. TQ™ terminals eliminate this risk with DEKRA-certified assurance to BS EN 61238-1:2003.
For a connection that meets certification standards, you should only use SWA-approved crimping tools and die sets. These are precision-matched to ensure the correct compression force and contact area. Using an unapproved tool can lead to poor conductivity, compromised joints, or voided compliance.
TQ™ terminals are specifically designed for copper conductors and must match the correct cable cross-section. Always check the terminal size against the conductor size and use the approved crimping die for a secure, compliant fit. They’re not suitable for aluminium cables or mixed-metal applications.
The TQ™ range covers 10 mm² to 630 mm² conductor sizes with multiple stud hole options. This allows you to select the exact fit for your application, from small-scale panel builds to large-format power installations. Size charts and technical drawings are available in the downloadable datasheet.
DEKRA certification provides independent proof that TQ™ terminals meet all required safety and performance standards. It confirms that each terminal has passed rigorous mechanical and electrical testing, reducing the risk of overheating, connection failure, or insurance issues — giving installers and specifiers complete confidence in compliance.
TQ™ copper tube terminals are DEKRA-certified and tested to BS EN 61238-1:2003, proving full compliance for Class A crimped connections. Unlike generic terminals, they’re independently verified for safety, performance, and reliability, ensuring every connection delivers consistent, low-resistance conductivity.
