ABB Residual Current Circuit Breakers

- Aug 15, 2018 -

ABB Residual Current Circuit Breakers are the safest device to detect and trip against electrical leakage current, thus ensuring protection against electric shock caused by indirect contacts.

These devices must be used in series with MCBs or fuses which protect them from the potentially damaging thermal and dynamic stresses of any overcurrents.

They also act as the main disconnecting switch upstream of any derived MCBs.
