Abb Molded Case Circuit Breaker

Miniature circuit breakers are used for single-phase and three-phase short-circuit, overload, and overvoltage protection below 125A, including single-pole 1P, two-pole 2P, three-pole 3P, and four-pole 4P.

Miniature circuit breakers are suitable for overload and short circuit protection of AC 50/60Hz rated voltage 230/400V, rated current up to 63A lines, and can also be used for infrequent operation conversion of lines under normal conditions. Miniature circuit breakers are mainly used in various places such as industrial, commercial, high-rise and residential buildings.
