Finding the right device for youSelection tool and guidelines from Doepke for selecting residual current circuit-breakers

There is not just one kind of RCCB (Residual Current operated Circuit-Breaker), rather a whole range of different types: two or four-pole, residual current type AC (detect AC residual currents and are not permitted in Germany), A (for AC and pulsating DC residual currents), F (also detect mixed frequencies) B and B+ (AC-DC sensitive). RCCBs can be slow-blow versions or have increased surge current strength, have selective tripping, be specifically tailored to the requirements of electromobility, be adapted for harsh environmental conditions or be built for facilities at risk of fire.
