The ABB S203M-C32NA is a professional miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in commercial, industrial and building electrical installations. As part of the trusted ABB System pro M compact S200M series, it delivers dependable current-limiting protection for distribution boards, switchboards and control panels.
This miniature circuit breaker features a C curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as lighting, socket outlets, small motors and general-purpose power distribution. Its thermal and electromechanical trip mechanisms help protect cables and connected equipment during overload and short-circuit conditions.
With a rated current of 32 A, a 3+NP pole configuration and a breaking capacity of up to 10 kA at 230 / 400 V AC, the S203M-C32NA is ideal for three-phase electrical systems requiring neutral switching. Its compact DIN rail design supports quick installation in modular electrical enclosures.
Miniature circuit breakers such as the ABB S203M-C32NA automatically disconnect electrical circuits during overload or short-circuit conditions. This helps protect cables, connected equipment and electrical infrastructure while supporting safe and compliant installation design.
The ABB S200M range is engineered for professional applications requiring compact dimensions, dependable operation and high breaking capacity. The C curve characteristic makes this model suitable for general distribution circuits and loads with moderate starting currents.
