Molded Case Circuit Breakers (MCCB) questions
What is the difference between an MCCB and an ACB?
An MCCB is a compact molded-case breaker, typically used from tens of amperes to 1600 A. An ACB is a larger, often draw-out breaker for main incomers from 630 A upward.
What do Icu and Ics mean on an MCCB?
Icu is the ultimate breaking capacity. Ics is the service breaking capacity, the share of Icu after which the breaker stays fit for service.
Do you export MCCBs and their accessories?
