Applications & Use Cases

The ABB SH202M-C20 miniature circuit breaker is well suited for protecting final circuits in residential distribution boards, commercial fit-outs, and light industrial control panels. The C-curve tripping characteristic makes it ideal for resistive and moderately inductive loads such as lighting circuits, socket outlets, and small motor applications where moderate inrush currents are present. Its compact DIN rail footprint simplifies panel layout and reduces overall enclosure size for engineers and panel builders.
