Why Choose the ABB SN201-B32 Miniature Circuit Breaker?
The ABB SN201-B32 is a compact and reliable 1P+N miniature circuit breaker (MCB) designed to protect final distribution circuits against overloads and short circuits. As part of the ABB System pro M compact SN201 series, it combines one protected phase pole with a switched neutral in a space-saving single-module design.
Featuring a 32 A rated current, Type B tripping characteristic and 6 kA rated short-circuit breaking capacity, the SN201-B32 provides dependable protection for residential and commercial electrical installations. Its Type B characteristic is intended for circuits with relatively low inrush currents, making it suitable for appropriate general-purpose final distribution loads.
The SN201-B32 operates at a rated voltage of 230 V AC and conforms to IEC/EN 60898-1. Its 1P+N configuration switches the neutral conductor together with the protected phase, while the single-module format helps minimise DIN-rail space requirements in compact distribution boards and electrical panels.
Key Advantages
- Compact 1P+N miniature circuit breaker in a single-module format.
- 32 A rated current for final distribution circuit protection.
- Type B tripping characteristic for circuits with relatively low inrush currents.
- 6 kA rated short-circuit breaking capacity according to IEC/EN 60898-1.
- Provides combined overload and short-circuit protection.
- Switched neutral provides simultaneous phase and neutral disconnection.
- Compact construction helps maximise available DIN-rail space.

- Single-module design for space-efficient DIN-rail installation.
- Suitable for residential and commercial final distribution applications.
Reliable Circuit Protection for Final Distribution
Miniature circuit breakers such as the ABB SN201-B32 automatically disconnect a circuit when excessive current occurs because of an overload or short circuit. This protects electrical conductors and connected equipment from damaging fault currents while allowing the breaker to be reset after the cause of the fault has been identified and corrected.
The SN201 series is particularly useful where distribution-board space is limited because its 1P+N arrangement combines phase protection and neutral switching within a single modular width. The SN201-B32 therefore provides a practical solution for compact residential and commercial final distribution systems requiring a 32 A Type B protective device.
Typical Applications
- Residential electrical distribution boards.
- Commercial electrical installations.
- Final distribution circuits.
- General-purpose electrical loads with relatively low inrush current.
- Building services distribution systems.
- Compact DIN-rail electrical panels and consumer units.
