1SYS273012R0404

The ABB SB203M-C40 (Part Number: 1SYS273012R0404) is a high-performance three-pole Miniature Circuit Breaker (MCB) from ABB's System pro M compact SB200M series, engineered to provide dependable overload and short-circuit protection for low-voltage electrical distribution and control systems.

Featuring a rated current of 40 Amperes, a C-curve tripping characteristic, and a 10kA short-circuit breaking capacity, this ABB miniature circuit breaker provides reliable electrical protection for residential, commercial, and suitable industrial electrical installations.

The ABB SB203M-C40 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. These mechanisms help protect electrical wiring, distribution circuits, and connected equipment against excessive current conditions.
