1SYS273012R0984

The ABB SB203M-C0.5 (Part Number: 1SYS273012R0984) 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 in low-voltage electrical distribution systems.

Featuring a rated current of 0.5 Amperes, a C-curve tripping characteristic, and a 10kA short-circuit breaking capacity, this ABB miniature circuit breaker is designed for low-current electrical circuits requiring dependable fault protection and reliable switching performance.

The ABB SB203M-C0.5 incorporates thermal-magnetic protection technology. Its thermal tripping mechanism responds to sustained overload conditions, while its electromagnetic tripping mechanism provides rapid circuit interruption during short-circuit faults, helping protect electrical wiring, distribution circuits, and connected equipment.
