Rated at 2.5 A continuous, with an adjustable overload release that dials from 1.8 A up to 2.5 A, it covers fractional-horsepower motors — think a 0.75 kW (1 hp) motor at 400 V three-phase. The magnetic short-circuit trip is fixed; the overload element is thermal, so ambient temperature in the enclosure matters for accurate tripping.
Screw terminals top and bottom, M3 screws torqued to 0.8–1.2 N·m. Mounting position is unrestricted — lay it flat, sideways, upside down, it trips the same. The S00 width is 45 mm, so it occupies one standard module slot on the rail.
How it sits against the 3RV1011-1HA10
The 3RV1011-1HA10 is the higher-current sibling in the same S00 frame — same physical footprint, same DIN rail clip, same screw terminals. It carries an 8 A rating (adjustable 5.5...8 A overload) and a 50 kA interrupting capacity at 400 V AC, versus this part's 13 kA at 400 V. Both share the S00 contactor combability and 100 000 electrical cycles typical endurance.
