Product name：RCD power breaker
A ground fault circuit interrupter circuit breaker (GFCI breaker inUSAandCanada) and residual-current breaker with overload (RCBO in Europe) are devices that combine the functions of a residual-current device with a circuit breaker. They detect both supply imbalance and overload current.
In Europe, RCDs can fit on the same DIN rail as the MCBs, however the busbar arrangements in consumer units and distribution boards can make it awkward to use them in this way. If it is desired to protect an individual circuit, an RCBO (residual-current circuit breaker with overcurrent protection) can be used. This incorporates an RCD and a miniature circuit breaker in one device.
Electrical plugs with incorporated RCD are sometimes installed on appliances that might be considered to pose a particular safety hazard, for example long extension leads, which might be used outdoors, or garden equipment or hair dryers, which may be used near a bath or sink. Occasionally an in-line RCD may be used to serve a similar function to one in a plug. By putting the RCD in the extension lead, protection is provided at whatever outlet is used even if the building has old wiring, such as knob and tube, or wiring that does not contain a grounding conductor.
In North America, GFI receptacles can be used in cases where there is no grounding conductor, but they must be labeled.
