1SYS273112R0044

The ABB SB203M-C4 NA (Part Number: 1SYS273112R0044) is a high-performance Triple Pole and Neutral (TPN) Miniature Circuit Breaker from ABB's System pro M compact SB200M series, designed to provide 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 ABB miniature circuit breaker provides dependable electrical protection for low-current three-phase installations in commercial and industrial environments.

The ABB SB203M-C4 NA 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 protection mechanisms help protect electrical wiring, control circuits, and connected equipment against excessive current conditions.
