CtecX3B 10kA Type B RCCBs

Techna’s CtecX3B 10kA Type B Residual Current Circuit Breakers (RCCBs) are suitable for use on 50Hz and 60Hz networks where pulsating DC, smooth DC or high frequency AC residual current faults may occur. These 10kA Type B RCCBs have been designed to operate in applications such as frequency inverters, medical devices, universal power supplies, mobile installations, lifts, electric vehicle charging and similar applications.

Our CtecX3B 10kA Type B RCCBs come with inbuilt test buttons and are available in 2 pole or 4 pole, in current ratings from 25A to 80A and with residual current sensitivity from 30mA to 500mA.

The CtecX3B Type B residual current circuit breakers are suitable for mounting on DIN-Rail and can also be used inside our Dtec Distribution Boxes and our WINtec IP67 Protection Windows.
