Why Choose the ABB S804S-B50 High Performance MCB?
The ABB S804S-B50 is a high-performance four-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding industrial and commercial electrical installations. Part of the ABB S800S high-performance MCB series, this model combines a 50 A rated current, Type B tripping characteristic and high 50 kA short-circuit breaking capacity.
The S804S-B50 uses thermal and electromagnetic tripping mechanisms to protect conductors and connected equipment against sustained overloads and short-circuit faults. Its Type B characteristic is suited to circuits with relatively low normal inrush currents, including resistive loads, control circuits and general electrical distribution applications.
With four protected poles and a specified 50 kA short-circuit breaking capacity, the S804S-B50 provides coordinated multi-pole protection for installations where substantial prospective fault currents may occur. Its DIN-rail format supports straightforward integration into distribution boards and control panels, while the ABB order code for this exact breaker is 2CCS864001R0505.

Reliable Protection for Low-Inrush Circuits
The ABB S804S-B50 combines thermal overload protection with electromagnetic short-circuit protection. The thermal mechanism responds to sustained excessive current, while the magnetic mechanism rapidly disconnects the circuit during severe fault conditions, helping protect conductors and connected electrical equipment.
The Type B characteristic is suited to circuits where normal switching and starting currents are comparatively low. Combined with the high fault-interruption capability of the S800S platform, the S804S-B50 provides dependable 50 A four-pole protection for distribution, control and other low-inrush electrical circuits.
Typical Applications
- Industrial and commercial electrical distribution systems.
- Four-pole distribution and control circuits.
- Resistive and low-inrush electrical loads.
- Industrial control panels and switchboards.
- Building-services distribution equipment.
- Automation and machine-control installations.
