Why Choose the ABB SN201M-C25 Miniature Circuit Breaker?
The ABB SN201M-C25 is a compact 1P+NP miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits while simultaneously switching the neutral conductor. Part of the ABB System pro M compact SN201M range, it combines phase protection and neutral switching within a space-saving single-module format for final distribution applications.
Featuring a Type C tripping characteristic, the SN201M-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, non-protected neutral pole positioned on the right, allowing phase and neutral conductors to be disconnected simultaneously.
With a rated current of 25 A, rated operational voltage of 230 V AC and a rated short-circuit capacity of 10 kA, the SN201M-C25 provides high breaking capacity while retaining a compact 18 mm single-module format. ABB order code 2CSS275101R0254 identifies this specific 25 A Type C model.
Key Advantages
- Reliable overload and short-circuit protection for final distribution circuits.
- 25 A rated current suitable for a range of residential and commercial applications.

High-Breaking-Capacity Phase and Neutral Protection
Miniature circuit breakers such as the ABB SN201M-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 SN201M-C25 combines this protection with simultaneous neutral switching in a compact single-module arrangement. Its Type C characteristic accommodates moderate normal inrush currents, while the 10 kA short-circuit capacity makes the SN201M range suitable for final distribution applications requiring higher fault-current capability and protection of suitable long cable lengths in TN and IT systems.
Typical Applications
- Residential final distribution circuits.
- Commercial electrical installations.
- General-purpose circuits with moderate inrush currents.
- Industrial control and auxiliary circuits.
- Protection of suitable long cable lengths in TN and IT systems.
- Distribution boards requiring a 10 kA MCB.
- Installations requiring simultaneous phase and neutral switching.
