Why Choose the ABB S804S-C8-R High-Performance Miniature Circuit Breaker?
The ABB S804S-C8-R is a high-performance 4-pole miniature circuit breaker (MCB) designed to protect cables, conductors and connected equipment against overload and short-circuit conditions. Part of the proven ABB S800S high-performance circuit breaker series, it combines an 8 A rated current, C tripping characteristic and high short-circuit breaking capability for demanding industrial electrical installations.
The S804S-C8-R uses a thermal release mechanism for dependable overload protection together with an electromechanical release for rapid short-circuit protection. Its current-limiting construction and fast arc-extinction system help minimise the energy passed through during severe faults, reducing thermal and electrodynamic stresses on the protected installation.
With a 4-pole configuration, 400 V rated voltage and 50 kA Icu short-circuit breaking capacity at 400 V AC, the S804S-C8-R provides robust protection for demanding distribution and equipment circuits. The R version features ring-terminal connections, while its C characteristic makes it suitable for general industrial circuits where moderate switching or starting currents can occur.

Reliable High-Performance Circuit Protection
The ABB S804S-C8-R combines thermal overload protection with rapid electromechanical short-circuit interruption. During a sustained overload, the thermal release disconnects the circuit before excessive conductor heating can cause damage, while high fault currents activate the electromechanical release for fast disconnection.
The C characteristic provides a practical balance between fault protection and tolerance of moderate transient currents, making the S804S-C8-R suitable for a broad range of industrial loads. Combined with the S800S series' high breaking capacity and fast arc extinction, this provides dependable protection in installations with substantial prospective short-circuit currents.
Typical Applications
- Industrial electrical distribution boards.
- Machinery and automation control panels.
- Commercial electrical distribution systems.
- Four-pole equipment and distribution circuits.
- Control and auxiliary power circuits.
- Industrial manufacturing and process equipment.
- Installations with high prospective short-circuit currents.
