Description
Type B RCD RCCB General:
Type B RCD is The most suitable leakage protector for us now and in the future. With the diversification of energy and equipments use, the interactive use of AC and DC, and the products with many different waveform signals, we need higher-level residual current protection circuit breakers to protect our personal safety and avoid the danger of electric shock.
Type B RCD 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.
