Why Choose the ABB SN201-C25 Miniature Circuit Breaker?
The ABB SN201-C25 is a compact 1P+N miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits while providing simultaneous switching of the neutral pole. Part of the ABB System pro M compact SN201 range, its single-module construction provides phase protection and neutral switching in a space-saving format suitable for final distribution applications.
Featuring a Type C tripping characteristic, the SN201-C25 is suitable for general-purpose circuits and equipment with moderate starting or inrush currents. The device incorporates one overcurrent-protected phase pole together with a switched neutral pole, allowing both conductors to be disconnected simultaneously while overcurrent protection is provided on the phase conductor.
With a rated current of 25 A, rated operational voltage of 230 V AC and short-circuit capacities of 6 kA to IEC/EN 60898-1 and 10 kA Icu, the SN201-C25 provides dependable circuit protection in a compact single-module device. ABB order code 2CSS255101R0254 identifies this specific 25 A Type C model.

Compact Phase and Neutral Circuit Protection
Miniature circuit breakers such as the ABB SN201-C25 automatically disconnect the protected phase conductor when an overload or short circuit occurs. Thermal and electromagnetic tripping mechanisms provide protection against sustained overcurrents and short-circuit faults, helping protect conductors, equipment and connected loads.
The SN201-C25 combines this protection with simultaneous neutral switching in a compact single-module arrangement. Its Type C characteristic makes it suitable for circuits that can experience moderate inrush currents during normal operation, while its 1P+N construction provides convenient simultaneous phase and neutral disconnection for final distribution applications.
Typical Applications
- Residential final distribution circuits.
- Commercial electrical installations.
- General-purpose electrical circuits.
- Industrial control and auxiliary circuits.
- Final distribution and suitable long-cable circuits in TN and IT systems.
- Distribution boards where DIN-rail space is limited.
- Circuits requiring simultaneous phase and neutral switching.
