Rated 2.5 A operational current at AC-3 (690 V max), it handles motor switching duty up to that current, with a magnetic short-circuit trip set at 33 A instantaneous. That trip point is the key selectivity number: below 33 A, overloads ride through; above it, the breaker clears before downstream components take damage.
Size S00 frame — 45 mm wide, 97 mm tall, 96 mm deep — so it occupies a standard single-module width on the rail. That 96 mm depth is the dimension to check against enclosure depth when the breaker sits behind a door or inside a shallow cabinet.
