1SYS273112R0014

The ABB SB203M-C1 NA (Part Number: 1SYS273112R0014) is a high-quality Triple Pole and Neutral (TPN) Miniature Circuit Breaker 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 1 Ampere, a C-curve tripping characteristic, and a 10kA short-circuit breaking capacity, this ABB miniature circuit breaker is designed for low-current three-phase electrical circuits requiring reliable protection and coordinated switching.

The ABB SB203M-C1 NA incorporates thermal-magnetic protection technology. Its delayed thermal tripping mechanism responds to sustained overload conditions, while its electromagnetic tripping mechanism enables rapid circuit interruption during short-circuit faults. These mechanisms help protect electrical wiring, control circuits, and connected equipment against abnormal current conditions.
