Type B RCD 40A 63A 30mA 4Pole B Type RCCB Earth Leakage Circuit Breaker
Type B RCCBs, in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire and or electrocution through automatic disconnection of the electrical supply relies on the selection of the correct type of RCCB EKL1-63B.

EKL1-63 Type B RCDs can detect sinusoidal AC, pulsating DC, composite of multi-frequency as well as smooth DC residual currents. In addition, tripping conditions are defined with different frequencies from 50Hz to 1kHz. In an AC electrical distribution network, a pure DC residual current can be mainly generated from three-phase rectifying circuits, but also from some specific single phase rectifiers.MIDA-80B Type B RCD are intended to be used for loads with three-phase rectifier, such as variable speed drives, PV system, EV charging station and medical equipment.
