RCCB (Residual Current Circuit Breaker)

RCCB (Residual Current Circuit Breaker)

RCCB means Residual Current Circuit Breaker -- A residual current device (RCD), or residual current. circuit breaker (RCCB), is an electrical wiring device that. disconnects a circuit whenever it detects that the electric. current is not balanced between the phase to neutral.  

A RCCB is an essential current sensing equipment used to guard a low voltage circuit from the fault. It comprises of a switch device used to turn off the circuit when a fault occurs in the circuit. RCCB is aimed at guarding a person from the electrical shocks.

A residual-current device, or residual-current circuit breaker, is a device that instantly breaks an electric circuit to prevent serious harm from an ongoing electric shock. RCCB are the safest device to detect and trip against electrical leakage currents, thus ensuring protection against electric .

What is the purpose of an Rccb?

Residual Current Circuit Breaker (RCCB) is a differential current sensing device used to protect a low voltage circuit in case of a leakage fault. It is sometimes also known as Residual Current Device (RCD).

What is difference between Rccb and Rcbo?

The major difference between a RCCB and RCBO is, a RCCB provides only leakage protection, were as RCBO provides, “over load+short circuit+leakage protection”. That means a RCBO is a combination of RCCB and MCB. ... RCBO is Short circuit current protection device as well as earth leakage protection device.
