1SYS273112R0324

The ABB 1SYS273112R0324 Miniature Circuit Breaker (MCB) is a low-voltage electrical circuit protection device from ABB’s System pro M compact SB200M series. It is designed to protect electrical circuits against overloads and short-circuit faults in residential, commercial and industrial electrical distribution installations.

Featuring a rated current of 32 A, a C-type tripping characteristic and a rated short-circuit breaking capacity of 10 kA, this circuit breaker is suitable for compatible electrical circuits with moderate inrush currents. The thermal tripping mechanism provides protection against sustained overloads, while the electromagnetic tripping mechanism enables rapid interruption during short-circuit conditions.

Its four-pole, three-phase-plus-neutral (3P+N/TPN) configuration is intended for compatible three-phase distribution systems. The compact design supports installation in suitable electrical distribution boards and control panels, helping simplify integration into low-voltage switchgear assemblies.
