1SYS272012R0255

ABB SB202M-B25 Miniature Circuit Breaker, Part Number 1SYS272012R0255, a high-quality low-voltage electrical circuit protection device designed for residential, commercial and industrial electrical distribution systems.

The ABB SB202M-B25 belongs to ABB's System pro M SB200M series of miniature circuit breakers and is designed to provide reliable protection against electrical overloads and short-circuit faults. Featuring a rated current of 25 amperes, double-pole (2P) configuration, B-curve tripping characteristic and 10kA rated short-circuit breaking capacity, this MCB is suitable for appropriately designed 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, where overcurrent protection is provided on the phase conductor only, the ABB SB202M-B25 features two protected poles.
