Type B RCD 4Pole 100A 10KA 100mA 300mA Type B RCCB 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 EKL1-63.
