Main contacts accept 2x (0.25 to 2.5 mm²) solid or 2x (0.25 to 1.5 mm²) finely stranded with ferrule. AWG equivalent is 2x (24 to 14). Mounting position is any orientation; zero clearance needed at the sides or rear (0 mm backwards, 0 mm at the side), so it packs tight against adjacent devices on the rail. ## Protection features and thermal load Ground fault detection is not included; that requires an add-on module or separate RCD. Power dissipation in hot operating state is 5.5 W total, 1.8 W per pole. That's the heat you need to vent in a sealed enclosure; at 0.32 A continuous it's modest, but the Class 10 curve means short overloads dump more heat into the bimetal. An auxiliary switch can be added via the product extension slot — the base unit ships without one, but the option is there for remote status feedback.","metaTitle":"Siemens 3RV1011-0DA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1011-0DA20 SIRIUS motor protection circuit breaker, 0.32 A rated current, Class 10 trip, 100 kA breaking capacity at 400 V.
