Why Choose the ABB S802C-B40 Miniature Circuit Breaker?
The ABB S802C-B40 is a high-performance two-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the ABB S800C high-performance circuit breaker series, it combines high breaking capacity, current-limiting performance and robust construction for residential, commercial and industrial electrical installations.
This MCB features a Type B tripping characteristic, making it suitable for circuits with relatively low starting or inrush currents. Separate thermal and electromechanical tripping mechanisms provide overload and short-circuit protection, while ABB's fast arc-extinction design helps limit fault energy during short-circuit conditions.
With a rated current of 40 A, a two-pole configuration and a maximum breaking capacity of 25 kA at 240/415 V AC, the S802C-B40 provides high-performance protection for demanding electrical systems. It can be used at voltages up to 254/440 V AC and is also suitable for DC applications within its specified ratings.

High-Performance Two-Pole Circuit Protection
Miniature circuit breakers such as the ABB S802C-B40 automatically disconnect electrical circuits when excessive current occurs because of an overload or short circuit. The S800C series uses a thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection, while its current-limiting design and rapid arc extinction help minimise fault energy.
The Type B characteristic makes the S802C-B40 suitable for appropriate circuits with relatively low inrush currents. Combined with its 40 A current rating, two-pole construction and 25 kA maximum breaking capacity, it provides a robust protection solution for distribution systems, control equipment and other demanding electrical installations.
Typical Applications
- Commercial electrical distribution systems.
- Industrial control panels and switchgear.
- General-purpose circuits with relatively low inrush currents.
- Resistive and appropriate general electrical loads.
- Machine control and automation equipment.
- Two-pole circuits requiring high short-circuit breaking capacity.
