The ABB S202-D8 is a 2-pole miniature circuit breaker rated 8 A with a Trip Curve D characteristic, designed for DIN-rail mounting. The Curve D trip suits loads with high inrush currents. The 6 kA interrupting rating at 277 VAC covers most commercial and light industrial fault levels without cascading upstream.
Mounts on standard 35 mm DIN rail. The 2-pole width (2 modules, ~36 mm) fits a single slot in a distribution board or sub-panel. No special busbar or comb required for the line-side connection — standard screw-clamp terminals accept up to 25 mm² conductor.
