What it is and where it fits
The SH201-C10 is an ABB miniature circuit breaker (MCB) from the SH201 series, designed for DIN-rail mounting in distribution boards and control panels. It's a 1-pole unit with a C-trip curve, rated for overcurrent and short-circuit protection of branch circuits. The C-curve characteristic means it trips between 5 and 10 times rated current — standard for protecting inductive loads like contactor coils, small motors, and lighting circuits where inrush isn't extreme.
Panel fit and integration
Snaps onto standard 35 mm DIN rail per EN 60715. The 1-pole width (roughly 18 mm per pole) means it occupies one module position in a distribution board. Busbar comb connections are standard for the SH201 family.
