ABB S202-K8 MCB – S200 – 2P – K – 8A

Why Choose the ABB S202-K8 Miniature Circuit Breaker?

The ABB S202-K8 is a compact and reliable 2 pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the proven ABB System pro M Compact S200 series, it provides dependable circuit protection for commercial, industrial and control panel applications.

This MCB features a K trip characteristic, making it particularly suitable for circuits with higher inrush currents, including motor control circuits, transformers and inductive loads. Its current limiting design helps reduce fault energy, improving protection for cables, equipment and downstream components.

With a rated current of 8 A, a 2 pole configuration and a 6 kA breaking capacity, the ABB S202-K8 offers robust protection in a compact DIN rail mounted format. It is ideal for professional electrical installations where reliable switching, circuit protection and ABB accessory compatibility are required.
