1SYS273012R0034

The ABB SB203M-C3 (Part Number: 1SYS273012R0034) is a high-quality three-pole Miniature Circuit Breaker (MCB) from ABB's System pro M compact SB200M series, designed to deliver reliable overload and short-circuit protection for low-voltage electrical distribution systems and control circuits.

Featuring a rated current of 3 Amperes, a C-curve tripping characteristic, and a 10kA short-circuit breaking capacity, this ABB miniature circuit breaker provides efficient protection for low-current electrical installations in residential, commercial, and suitable industrial environments.

The ABB SB203M-C3 incorporates thermal-magnetic protection technology. Its thermal tripping mechanism responds to prolonged overload conditions, while the electromagnetic mechanism provides rapid disconnection during short-circuit faults, helping protect electrical wiring, distribution circuits, and connected equipment.
