The S202-C2 is a 2-pole miniature circuit breaker rated at 2 A with a Trip Curve C characteristic, meaning it trips at 5–10 times rated current — suited for moderate inrush loads like small motors, transformers, or lighting banks that don't need the time delay of Curve D or the fast trip of Curve B.
Where it lives in the panel
Snaps onto standard DIN rail — the same 35 mm profile every panel builder knows. Two poles means it switches both line and load conductors in a single module width, so it fits a 2-pole space in the distribution board. No special tools for install; the spring-loaded clip grabs the rail and the busbar stabs in behind it. If you're swapping an existing unit, the footprint is the same as any System pro M compact series 2-pole breaker.
