Residual-current device

RCDs are designed to disconnect the conducting wires ("trip") quickly enough to potentially prevent serious injury to humans, and to prevent damage to electrical devices. A two-pole, or double-pole,

Residual Current Protective Devices

Residual current operated circuit breakers with overcurrent protection (RCBOs) include residual current detection and overcurrent protection in one device and thus enable a combination of electric-shock

Inevitable in almost all electrical switchboards

The Magic of Residual Current DeviceOperating Principle of RCDThe Choice of A Residual Current DeviceThe Choice of Protection DeviceAdvantages of Residual Current DevicesThe choice of a residual current device depends on the required level of protection (trip threshold sensitivity I∆n), on the nature of the associated breaking device (circuit breaker or switch) and the specific conditions of use (delayed, discriminating, immune).See more on electrical-engineering-portal Siemens
