1SYS272012R0105

ABB SB202M-B10 Miniature Circuit Breaker, Part Number 1SYS272012R0105, a high-quality low-voltage circuit protection device designed for residential, commercial and industrial electrical distribution systems.

The ABB SB202M-B10 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 10 amperes, a double-pole (2P) configuration, B-curve tripping characteristic and 10kA short-circuit breaking capacity, this MCB is suitable for correctly designed electrical distribution circuits.

The double-pole configuration provides thermal-magnetic overcurrent protection in both poles, enabling simultaneous disconnection of two conductors during manual switching or protective tripping. Unlike a single-pole plus neutral MCB, which protects only the phase conductor, the ABB SB202M-B10 features two protected poles.
