ABB S203P-C32NA System pro M compact S200P miniature circuit breaker with 3P+N configuration, 32 A rated current, C tripping characteristic and 15 kA breaking capacity for commercial and industrial circuit protection.
The ABB S203P-C32NA is a high-performance 3P+N miniature circuit breaker (MCB) from the ABB System pro M compact S200P series. Designed for dependable overload and short circuit protection, it provides reliable circuit protection for industrial distribution boards, commercial installations, machinery and OEM electrical panels.
This miniature circuit breaker features a C tripping characteristic and a 32 A rated current, making it suitable for general-purpose circuits with moderate inrush currents. It is commonly used for lighting, power distribution, control panels and industrial loads where dependable protection and operational stability are required.
With a 3P+N configuration and a high 15 kA breaking capacity at 400 V AC, the S203P-C32NA provides professional-grade protection in demanding three-phase electrical systems. Its compact DIN rail mounted format supports quick installation within switchboards, distribution boards and machine control cabinets.
Miniature circuit breakers such as the ABB S203P-C32NA protect electrical installations by automatically disconnecting the circuit during overload or short circuit conditions. The thermal trip mechanism responds to sustained overloads, while the electromagnetic trip mechanism provides rapid protection against short circuit faults.
The C curve characteristic is suitable for circuits with moderate inrush currents, making the S203P-C32NA a practical choice for lighting systems, socket circuits, distribution boards, machinery and general industrial loads. Its compact modular design supports efficient panel building and long-term installation reliability.
