CtecUL 10kA RCCBs

Techna’s CtecUL 10kA Residual Current Circuit Breakers (RCCBs) are UL Listed as Ground Fault Sensing and Relaying Equipment to Standard 1053, File E475399. Our CtecUL Equipment Ground Fault Protection Relays provide ground fault (residual current) protection for circuits with loads up to 63A with a short circuit interrupting capacity of 10kA.

Our range of CtecUL 10kA Equipment Ground Fault Protection Relays are available in 2 pole or 4 pole, in current ratings 25A, 40A and 63A and with residual current sensitivity from 10mA to 500mA.

The CtecUL equipment ground fault protection relays are suitable for mounting on DIN-Rail and can also be used inside our Dtec Distribution Boxes and our WINtec IP67 Protection Windows.
