1SYS272012R0205

ABB SB202M-B20 Miniature Circuit Breaker, Part Number 1SYS272012R0205, a high-quality low-voltage electrical protection device designed for residential, commercial and industrial electrical distribution systems.

The ABB SB202M-B20 belongs to ABB's System pro M SB200M series of miniature circuit breakers and is engineered to provide protection against electrical overload and short-circuit faults. Featuring a rated current of 20 amperes, a double-pole (2P) configuration, B-curve tripping characteristic and 10kA short-circuit breaking capacity, this MCB provides reliable circuit protection for appropriately designed electrical installations.

The double-pole configuration incorporates thermal-magnetic overcurrent protection in both poles, allowing simultaneous disconnection of two conductors during manual switching or protective tripping. Unlike a single-pole plus neutral MCB, which provides overcurrent protection in the phase conductor only, the ABB SB202M-B20 offers overcurrent protection in both poles.
