1SYS273112R0164

The ABB 1SYS273112R0164 Miniature Circuit Breaker (MCB) is a current-limiting electrical protection device from ABB’s System pro M compact SB200M series. It is designed to protect low-voltage electrical circuits against overloads and short-circuit faults in residential, commercial and industrial installations. The device features a rated current of 16 A, a C-type tripping characteristic and a rated short-circuit breaking capacity of 10 kA at the specified operating voltage.

This MCB incorporates two tripping mechanisms: a thermal mechanism with delayed operation for overload protection and an electromagnetic mechanism for rapid response to short-circuit faults. Its 3P+N configuration provides three-phase and neutral switching functionality, making it suitable for compatible three-phase distribution circuits.
