Why Choose the ABB SH203-B25 Miniature Circuit Breaker?
The ABB SH203-B25 is a compact and dependable three-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in three-phase electrical circuits. As part of the ABB SH200 miniature circuit breaker series, it combines thermal-magnetic protection with a modular DIN-rail design for reliable circuit protection in electrical distribution systems.
This miniature circuit breaker has a 25 A rated current, Type B tripping characteristic and 6 kA rated short-circuit breaking capacity. The Type B characteristic is suited to circuits with relatively low inrush currents, providing prompt magnetic operation under short-circuit conditions while maintaining dependable overload protection.
With its three-pole configuration, the SH203-B25 provides linked switching and protection across all three poles of a three-phase circuit. Its 25 A rating and compact modular construction make it a practical choice for suitable three-phase distribution, resistive-load and general electrical circuits requiring dependable ABB circuit protection.

Reliable Three-Phase Circuit Protection
Miniature circuit breakers such as the ABB SH203-B25 automatically disconnect an electrical circuit when excessive current results from an overload or short circuit. The thermal release responds to sustained overload conditions, while the magnetic release provides rapid operation when a high fault current occurs.
The Type B characteristic is particularly appropriate for circuits where normal starting currents are relatively low. Combined with its three-pole construction, 25 A rating and 6 kA breaking capacity, the SH203-B25 provides dependable protection for suitably designed three-phase electrical distribution circuits.
Typical Applications
- Three-phase electrical distribution circuits.
- Residential and commercial distribution boards.
- General-purpose three-phase electrical circuits.
- Circuits supplying resistive and low-inrush loads.
- Electrical distribution and sub-distribution panels.
- DIN-rail mounted modular protection assemblies.
