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.","metaTitle":"Siemens 3RV1011-1CA10-ZI45 SIRIUS Motor Circuit Breaker, CLA","metaDescription":"Siemens SIRIUS 3RV1011-1CA10-ZI45 motor circuit breaker, size S00, CLASS 10 trip class, adjustable 1.8...2.5 A overload, 750 W at 400 V.

It steps up to 8 A (adjustable 5.5...8 A) with a 50 kA interrupting capacity at 400 V, so it covers a higher motor current or a higher available fault current.
