Moulded Case Circuit Breakers

Moulded Case Circuit Breakers (MCCBs) function by automatically disconnecting the power supply when a short circuit fault is detected downstream or when the circuit becomes overloaded, surpassing the current capacity of the electrical cables. MCCBs are the typical choice of breaker in switchboards or for direct power supply to large equipment. They are particularly well-suited for commercial and industrial applications that demand a higher capacity for low voltage power compared to miniature circuit breakers (MCBs). NHP's moulded case circuit breakers provide high performance protection for circuits ranging from 20A to 3200A suitable for various AC and DC voltages. With a mixed blend of trip unit technologies there are suitable options for any application.
