MPCB-MOTOR PROTECTION CIRCUIT BREAKER
MCB-MINIATURE CIRCUIT BREAKER
MPCB TOTALY DIFFERENT FROM MCB AS IT IS NOT ONLY SIMPLE
CIRCUIT BREAKER AS MCB IT HAS INBUILT OVERLOAD RELAY RANGE
IF THE LOAD ON THE MOTOR EXCEEDS ITS CURRENT ABOVE THE
LIMIT OF MPCB IT TRIPS.
MCCB-MOULDED CAGE CIRCUIT BREAKER
MCCB IS A CIRCUIT BREAKER HAVING HAIGH LOAD CAPACITY THAT
IS ABOVE 63 AMPERE WE ARE GENERALY USE MCCB INSTED OF MCB
