1SYS273112R0974
Description
The ABB SB203M-C1.6 NA (Part Number: 1SYS273112R0974) is a high-performance Triple Pole and Neutral (TPN) Miniature Circuit Breaker from ABB's System pro M compact SB200M series, engineered to deliver reliable overload and short-circuit protection for low-voltage electrical distribution and control systems.
Featuring a rated current of 1.6 Amperes, 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 dependable fault protection and coordinated switching.
The ABB SB203M-C1.6 NA incorporates thermal-magnetic protection technology. Its thermal tripping mechanism responds to sustained overload conditions, while the electromagnetic tripping mechanism provides rapid circuit interruption during short-circuit faults. These mechanisms help protect electrical wiring, control circuits, distribution systems, and connected equipment against abnormal current conditions.
