Why Choose the ABB S804N-D32 High Performance MCB?
The ABB S804N-D32 is a high-performance 4-pole miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits in demanding commercial and industrial environments. Part of the ABB S800N high-performance MCB range, it combines four-pole protection with a high short-circuit breaking capacity and robust DIN rail construction.
Featuring a 32 A rated current and Type D tripping characteristic, the S804N-D32 is particularly suited to circuits supplying equipment with substantial starting or energisation currents. Its thermal and electromechanical tripping mechanisms provide overload and short-circuit protection while accommodating the temporary inrush currents associated with suitable motors, transformers and other inductive loads.
The S804N-D32 provides a rated ultimate short-circuit breaking capacity of 36 kA at 415 V AC, with additional breaking performance across AC and DC operating voltages. Its four-pole configuration, interchangeable cage-terminal design and high fault-current capability make it a robust choice for industrial distribution boards, machinery and multi-pole electrical systems.

High-Performance Protection for High Inrush Loads
Miniature circuit breakers such as the ABB S804N-D32 automatically interrupt electrical circuits when excessive current occurs because of an overload or short circuit. Thermal protection responds to sustained overload conditions, while the electromechanical short-circuit mechanism provides rapid interruption during severe fault conditions, helping protect conductors, connected equipment and the wider electrical installation.
The Type D characteristic makes the S804N-D32 particularly suitable for circuits supplying equipment that can draw substantial current during starting or energisation. Combined with its 36 kA breaking capacity at 415 V AC and four-pole construction, the breaker provides robust protection for demanding industrial circuits where both high inrush currents and high prospective short-circuit currents may occur.
Typical Applications
- Industrial electrical distribution boards.
- Motor circuits with high starting currents.
- Transformer protection circuits.
- Machinery and industrial control panels.
- Four-pole commercial and industrial electrical systems.
- Equipment with high switch-on or energisation currents.
