The adjustable overload release covers 0.18 to 0.25 A, so it's sized for fractional-horsepower motors or small control transformers drawing around that range. Rated operating current is 0.25 A at 400 V, with a power dissipation of 5.5 W in hot state (1.8 W per pole). ## Trip class and what it means on the bench CLASS 10 is the standard trip class for general-purpose motor starting: it lets the breaker ride through the inrush of a direct-on-line start (typically 6–8× FLA for a few seconds) but trips fast on a locked rotor. The magnetic short-circuit trip is fixed at 8.2 A — about 33× the rated current — so it clears a bolted fault before the thermal element has time to heat. That combination (thermal CLASS 10 overload + fixed magnetic short-circuit) is what you want for a small pump, fan, or conveyor drive where the motor is started unloaded or with a light load.","metaTitle":"Siemens 3RV1011-0CA10-ZI45 SIRIUS Motor Circuit Breaker, CLA","metaDescription":"Siemens SIRIUS 3RV1011-0CA10-ZI45 motor protection circuit breaker, size S00, CLASS 10 trip, adjustable 0.18-0.25 A, screw terminals.
