Why Choose the ABB S802S-B25 High Performance MCB?
The ABB S802S-B25 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding commercial and industrial installations. As part of the proven ABB S800S high-performance circuit breaker series, it combines compact modular construction with a high short-circuit breaking capacity.
This circuit breaker features a Type B tripping characteristic and a rated current of 25 A. The Type B characteristic provides sensitive short-circuit protection suitable for circuits with relatively low inrush currents, while the S800S design provides dependable thermal overload and magnetic short-circuit protection.
With a rated ultimate short-circuit breaking capacity of 50 kA at 415 V AC, the S802S-B25 is engineered for installations where high prospective fault currents require substantially greater interruption capability than conventional miniature circuit breakers. Its 2-pole configuration enables simultaneous protection and isolation of two conductors.

Reliable High-Performance Circuit Protection
Miniature circuit breakers such as the ABB S802S-B25 automatically disconnect an electrical circuit when excessive current results from an overload or short circuit. The S800S series is specifically designed for applications where high breaking capacity is required, helping protect electrical installations and downstream equipment from damaging fault currents.
The Type B characteristic is well suited to circuits with comparatively low inrush currents and provides responsive short-circuit protection. Combined with the S800S series' high interruption capability, this makes the S802S-B25 suitable for demanding commercial and industrial distribution systems where reliable circuit protection is essential.
Typical Applications
- Industrial electrical distribution systems.
- Commercial electrical installations.
- Machinery and automation control panels.
- Power distribution boards and switchgear.
- Circuits with low to moderate inrush currents.
- High fault-level electrical protection systems.
