What is the Difference Between MCCB & ACB & VCB
Answer Posted / hashim nooruddin
MCCB-- Moulded Case Circket Breaker
ACB -- Air Circket Breaker
VCB -- Vacume Circket Breaker
MCB we use from 0 to 64 Amp.
MCCB we use from 64 to 800 Amp
ACB we use above 800 Amp
More ever at much higher current level we use VCB because
at higher current the air around it get ionised and become
conducter which causes short ckt. so at much higher current
level we generaly use VCB.
