What is the Difference Between MCCB & ACB & VCB
Answer Posted / muhammad junaid afridi
MCCB stands for Moulded Case Ckt Breaker.
ACB Air Ckt Breaker.
VCB Vaccume Ckt Breaker..Its to Simple yar....
Summary....
MCCB (Molded Case Circuit Breaker)—rated current up to 2500
A. Thermal or thermal-magnetic operation. Trip current may
be adjustable in larger ratings.
Vacuum circuit breakers are circuit breakers which are used
to protect medium and high voltage circuits from dangerous
electrical situations.
Air circuit breaker—Rated current up to 10,000 A. Trip
characteristics are often fully adjustable including
configurable trip thresholds and delays.
