Why Choose the ABB S804S-C63 High-Performance Miniature Circuit Breaker?
The ABB S804S-C63 is a high-performance 4-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical distribution systems. Part of the proven ABB S800S high-performance circuit breaker series, it combines a 63 A rated current, C tripping characteristic and high short-circuit breaking capability for residential, commercial and industrial installations.
The S804S-C63 uses two complementary tripping mechanisms: a thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection. Its current-limiting design and rapid arc extinction help minimise the effects of high fault currents and protect downstream equipment and electrical infrastructure.
With four poles, a 50 kA rated ultimate short-circuit breaking capacity at 240/415 V AC and suitability for systems up to 400/690 V AC, the S804S-C63 is particularly suited to installations where high fault levels demand robust circuit protection. Interchangeable cage terminals and compatibility with ABB S800 accessories support efficient installation and system integration.

- Interchangeable cage terminal connection system.
- Complies with IEC/EN 60898-1 and IEC/EN 60947-2.
Reliable High-Performance Circuit Protection
The ABB S804S-C63 protects electrical circuits through coordinated thermal and electromechanical tripping. The thermal mechanism responds to sustained overload conditions, while the electromechanical mechanism provides rapid operation during short-circuit faults. This combination helps prevent excessive conductor heating and limits the energy passed through to downstream equipment.
As a current-limiting circuit breaker from the ABB S800S family, the S804S-C63 is engineered for installations with higher prospective fault currents than conventional miniature circuit breakers may be designed to handle. Its fast arc-extinction system, high breaking capacity and four-pole configuration make it well suited to robust distribution and machinery protection systems.
Typical Applications
- Industrial electrical distribution boards.
- Machinery and automation control panels.
- Commercial electrical installations.
- High-fault-level distribution circuits.
- Four-pole AC circuit protection.
- Manufacturing and process equipment.
- Building services and infrastructure installations.
