Residual Current Circuit Breaker Function
Residual current circuit breakers are aimed at protecting an individual from the risks of electrical shocks electrocution and fires that are caused due to faulty wiring or earth faults.
Residual current circuit breaker function. This is a protective device which combines two functions. Rccb is particularly useful in situations where there is a sudden earth fault occurring in the circuit. The circuit breaker is set at the capacity of the. Rccb residual current circuit breaker falls under the category of wide range of circuit breakers as we know there are several types of miniature circuit breakers like mccb which works on different operational principle and has different safety purposes.
Circuit breaker rccb is essentially a current sensing device used to protect a low voltage circuit in case of a fault. Residual current circuit breakers are aimed at protecting an individual from the risks of. A residual circuit breaker with overcurrent protection. Residual current circuit breaker is essentially a device which senses current and disconnects any low voltage unbalanced current.
Residual current devices protect people. The incoming current has to pass through the circuit breaker first before going to the phase coil. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit its basic function is to interrupt current flow after a fault is detected. Purpose of rccb.
Residual current circuit breaker with over current protection rcbos the range designed to ensure efficiency and protection rcbos are commonly used in applications where there is the need to combine protection against overcurrents overload and short circuit and protection against earth leakage currents. A circuit breaker breaks the circuit if the current demand gets too high. It contains a switch device that switches off whenever a fault occurs in the connected circuit. A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.
It acts as a residual current device and a circuit breaker. The return neutral path passes through the second circuit breaker pole.
