1SYS272012R0325

ABB SB202M-B32 Miniature Circuit Breaker, Part Number 1SYS272012R0325, a high-quality low-voltage circuit protection device designed for residential, commercial and industrial electrical distribution applications.

The ABB SB202M-B32 belongs to ABB's System pro M SB200M series of miniature circuit breakers and is engineered to provide dependable protection against electrical overloads and short-circuit faults. Featuring a rated current of 32 amperes, double-pole (2P) configuration, B-curve tripping characteristic and rated short-circuit breaking capacity of 10kA, this MCB is suitable for appropriately designed low-voltage electrical installations.

The double-pole configuration incorporates thermal-magnetic overcurrent protection in both poles, enabling simultaneous disconnection of two conductors during manual operation or protective tripping. Unlike a single-pole plus neutral MCB, which typically provides overcurrent protection in the phase conductor and switching of the neutral conductor, the ABB SB202M-B32 provides protection in both poles.
