Why Choose the ABB S804N-C40 Miniature Circuit Breaker?
The ABB S804N-C40 is a high-performance 4-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding commercial and industrial installations. Part of the ABB S800N high-performance circuit breaker series, it combines a rated current of 40 A with a high 36 kA short-circuit breaking capacity.
Featuring a Type C tripping characteristic, the S804N-C40 is suited to circuits supplying resistive and inductive loads with moderate starting or inrush currents. Thermal overload protection responds to sustained overcurrent conditions, while electromagnetic short-circuit protection provides rapid interruption during severe faults.
The S804N-C40 provides four protected poles, making it suitable for four-pole and three-phase-plus-neutral distribution arrangements requiring coordinated protection and switching. Its current-limiting construction, modular DIN-rail format and compatibility with the ABB S800 accessory platform support integration into industrial distribution boards, machinery panels and automation systems.

Reliable Four-Pole Circuit Protection
High-performance miniature circuit breakers such as the ABB S804N-C40 automatically disconnect electrical circuits when excessive current results from an overload or short circuit. Thermal tripping responds to sustained overload conditions, while electromagnetic tripping provides rapid operation during severe short-circuit faults, helping protect conductors and connected equipment.
The Type C characteristic provides a practical balance between overcurrent protection and tolerance of normal temporary starting currents from suitable inductive equipment. Combined with four protected poles, high breaking capacity and the current-limiting performance of the S800N platform, the S804N-C40 provides robust protection for demanding commercial and industrial distribution systems.
Typical Applications
- Three-phase-plus-neutral industrial distribution circuits.
- Four-pole commercial and industrial distribution panels.
- Machinery and automation control cabinets.
- Resistive and inductive load circuits.
- Industrial control and auxiliary power systems.
- High fault-level installations requiring high-performance circuit protection.
