Techna’s RtecUL 10kA Residual Current Circuit Breakers with Overcurrent Protection (RCBOs) are UL Listed as Ground Fault Sensing and Relaying Equipment to Standard 1053, File E475399. Our RtecUL are combined Equipment Ground Fault Protection Relays and Overload Protectors, featuring dual pole switching (live and neutral disconnect) and designed to provide protection against short circuits, overloads, AC ground faults (residual current faults) as well as pulsating DC ground faults and has an interrupting capacity of 10kA. The RtecUL are also rated to UL 1077, File E243696, as a Supplementary Overload Protector.
Our range of RtecUL 10kA Equipment Ground Fault Protection Relays with inbuilt Overload Protection are available in 2 pole or 4 pole, in current ratings from 5A to 40A, with residual current sensitivity from 10mA to 500mA and are offered in trip curves B, C and D.
The RtecUL equipment ground fault protection relays with inbuilt overload protection are suitable for mounting on DIN-Rail and can also be used inside our Dtec Distribution Boxes and our WINtec IP67 Protection Windows.
