TOMZN TOB1-63H 4P 63A AC Miniature Circuit Breaker (MCB)

TOMZN TOB1-63H 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 for coordinated switching of three-phase and neutral conductors, making it suitable for residential, commercial, industrial and solar electrical installations. With a rated current of 63A and an operating voltage of 230/400V AC, the breaker supports 50/60Hz electrical systems and features a C-type tripping characteristic for general-purpose electrical distribution applications. Its thermal-magnetic protection mechanism automatically disconnects the circuit during overload or short-circuit conditions, helping protect connected wiring and electrical equipment. The breaker features a compact modular construction, fire-resistant insulating housing and manual ON/OFF operation for convenient circuit isolation. Designed for standard 35mm DIN-rail mounting, the TOMZN TOB1-63H is suitable for electrical distribution boards, solar inverter AC protection panels, commercial switchboards and industrial control panels.
