Why Choose the ABB S803N-D8 High Performance MCB?
The ABB S803N-D8 is a high-performance 3-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits where a high breaking capacity is required. As part of the ABB S800N high-performance MCB range, it provides robust circuit protection for demanding commercial and industrial electrical installations.
Featuring an 8 A rated current and Type D tripping characteristic, the S803N-D8 is particularly suitable for circuits supplying equipment with high inrush currents, including motors and transformers. Thermal tripping provides overload protection while electromechanical tripping responds rapidly to short-circuit conditions, helping protect cables, equipment and electrical distribution systems.
The S803N-D8 provides a maximum short-circuit breaking capacity of 36 kA at 240/415 V AC. Its three protected poles, current-limiting design and cage terminals make it suitable for industrial distribution boards, machinery and applications requiring selective or back-up circuit protection.

High-Performance Protection for High Inrush Loads
Miniature circuit breakers such as the ABB S803N-D8 automatically interrupt electrical circuits when excessive current occurs because of an overload or short circuit. The thermal tripping mechanism provides overload protection, while the electromechanical tripping mechanism responds rapidly to short-circuit faults to protect conductors, equipment and the wider electrical installation.
The Type D characteristic makes the S803N-D8 particularly suitable for loads that can produce high current peaks when switched on. Combined with the S800N range's high breaking capacity, this makes the breaker suitable for demanding motor, transformer and industrial equipment circuits where dependable protection and resistance to normal starting currents are required.
Typical Applications
- Industrial electrical distribution boards.
- Commercial power distribution systems.
- Motor circuits with high starting currents.
- LV/LV transformer circuits.
- Machinery and industrial control panels.
- Electrical equipment with high switch-on or inrush currents.
