1SYS273012R0044

The ABB SB203M-C4 (Part Number: 1SYS273012R0044) is a high-quality three-pole Miniature Circuit Breaker (MCB) from ABB's System pro M compact SB200M series, engineered to deliver reliable overload and short-circuit protection for low-voltage electrical distribution and control systems.

Featuring a rated current of 4 Amperes, a C-curve tripping characteristic, and a 10kA short-circuit breaking capacity, this miniature circuit breaker provides dependable protection for low-current residential, commercial, and suitable industrial electrical installations.

The ABB SB203M-C4 incorporates thermal-magnetic protection technology. Its delayed thermal tripping mechanism responds to sustained overload conditions, while its electromagnetic tripping mechanism enables rapid interruption during short-circuit faults, helping protect electrical wiring, distribution circuits, and connected equipment.
