The flow of current through electrical facilities always involves risks. Poorly insulated equipment, faulty wires and incorrect use of an electrical devise cause currents to flow through the wrong path (i.e., through the insulation) to the earth. This current is called ‘Leakage Current’.
Earth Leakage is an electrical hazard and is responsible for electrical shocks and fire risk. Earth Leakage and its associated hazard can be prevented by residual current device (RCD), similar to that of a residual current circuit breaker (RCCB), also popularly known as Earth Leakage Circuit Breaker (ELCB).
– Simple and Robust operating mechanism.

What is the difference between MCB & MCCB, Where it can be used,
MCB is miniature circuit breaker which is thermal oprated
and use for short circuit protection in small current
rating circuit. MCCB moulded case circuit breaker and is
thermal operated for over load current and magnetic
operation for instant trip in short circuit condition.under
voltage and under frequency may be inbuilt. Normally it is
used where normal current is more than 100A
MCB - MINIATURE CIRCUIT BREAKER
MCCB - MODULE CASE CIRCUIT BREAKER
MCB RATING : 63 AMP (MAXIMUM) i.e. in the form of tpn(
THREE PHASE + NUETRAL)
MCCB _ 63AMP (min.)
MCB IS USED WHERE LOAD IS LOW BUT MCCB IS USED WHERE LOAD
IS HIGH AND USE AS INCOMER.WHILE THE MCB IS USED FOR
