OMEGA OMB1-63H 4P 63A 400V AC Miniature Circuit Breaker (MCB) – Three Phase

OMEGA OMB1-63H 4P 63A AC Miniature Circuit Breaker (MCB) is designed to provide reliable overload and short-circuit protection for three-phase AC electrical distribution systems. The breaker features a four-pole configuration with a rated current of 63A, allowing coordinated switching and protection of four conductors in compatible electrical installations. With a rated operating voltage of 400V AC and a rated short-circuit breaking capacity of 6kA (6000A), the breaker is suitable for residential, commercial, industrial and solar electrical distribution applications. The C-type tripping characteristic makes the circuit breaker suitable for general-purpose electrical circuits and compatible loads with moderate starting currents. Its thermal-magnetic protection mechanism is designed to automatically disconnect the circuit during overload and short-circuit conditions, helping protect electrical wiring and connected equipment. The four-pole design features a common operating handle for simultaneous switching of all four poles, making it suitable for compatible three-phase and neutral electrical distribution systems. The breaker features a compact modular construction, visible switching position indicators and screw-terminal connections for convenient electrical installation. Designed for standard DIN-rail mounting, the OMEGA OMB1-63H is suitable for electrical distribution boards, solar inverter AC protection panels, commercial switchboards and industrial electrical installations. The breaker is marked with IEC/EN 60898-1 and GB/T 10963.1 standards for miniature circuit breakers used in electrical distribution systems.
