1SYS274012R0984

The ABB 1SYS274012R0984 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 compatible electrical circuits against overload currents and short-circuit faults in residential, commercial and industrial installations.

This model has a rated current of 0.5 A, a C-type tripping characteristic and a rated short-circuit breaking capacity of 10 kA. The thermal tripping mechanism provides delayed protection against sustained overloads, while the electromagnetic tripping mechanism enables rapid interruption during short-circuit conditions.

The device features a four-pole (4P) configuration for switching and protecting compatible circuits. Its compact construction supports installation in suitable electrical distribution boards and control panels. The insulating housing helps provide electrical separation and supports safe operation when the breaker is installed in accordance with the manufacturer's instructions.
