AC/DC sensitive residual current circuit-breakers (RCCBs) for detecting AC residual currents and pulsating and smooth DC residual currents
sensitive to residual currents and mixed frequencies from 0 Hz bis 20 kHz
The MI variant is also equipped with a tripping threshold of 6 mA for DC residual currents additional to the AC/DC sensitivity of Type B or B+. This prevents pre-magnetisation of upstream RCCBs type A or F, so that they can continue to fulfil their protective function.
HD design for use in extreme environments
