WHAT IS MCB?
A miniature circuit breaker
(MCB) automatically switches off the electrical circuit during an abnormal
condition of the network means in overload condition as well as faulty
condition.
What is RCCB?
A Residual Current Circuit Breaker (RCCB) is
essentially a current sensing device used to protect a low voltage circuit in
case of a fault. It contains a switch device that switches off whenever a fault
occurs in the connected circuit.
An Earth-leakage
circuit breaker (ELCB) is a safety device used in electrical
installations with high earth impedance to prevent shock. It
detects small stray voltages on the metal enclosures of electrical equipment and interrupts the circuit if a dangerous voltage is detected. Once widely
used, more recent installations instead use residual current circuit breaks which instead detect
leakage current directly.
