B Type RCCB Residual Current Circuit breaker
4Pole Type B RCD RCCB Residual Current 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 of the type of RCCB EKL1-63B.
