The S802S-D25 is a 2-pole miniature circuit breaker rated 25 A with a Trip Curve D characteristic, meaning its magnetic trip threshold is set to 10–20× In — designed for loads with high inrush currents like motor starters, transformers, and welding equipment where a standard B or C curve would nuisance-trip on startup. The DIN rail mounting means it clips onto standard 35 mm top-hat rail inside the enclosure — no panel cutouts or screw holes needed, which keeps swap time under a minute for a field tech.
Deployment context
Snaps onto DIN rail inside a control panel — typical for branch-circuit protection on motor feeds, power supplies, or lighting contactor coils where the 25 A rating and Curve D delay match the load profile.
