Product details

The Siemens SIRIUS 3RV1021-0DA10-ZX95 is a three-pole motor protection circuit breaker rated for a continuous current of 0.32 A, with a Trip Class 10 characteristic — meaning it will trip within 10 seconds at 7.2× rated current, matching the thermal curve of standard IEC induction motors up to 0.09 kW at 400 V AC.

Width is 45 mm (three 15 mm modules), height 97 mm, depth 96 mm, with zero clearance required at the sides or rear. Screw-type terminals on both main and auxiliary circuits accept solid or stranded conductors: 2× (1…2.5 mm²) and 2× (2.5…6 mm²), or AWG 14–10 for the main contacts. The auxiliary switch option (product extension auxiliary switch: Yes) allows adding a signal contact for remote status indication — useful for PLC feedback or alarm annunciation on a motor starter circuit.

RoHS compliance date is listed as 01.05.2012, indicating the part has been RoHS-compliant since that date. The substance prohibitance date aligns with EU RoHS requirements.

Frequently asked questions

Will 3RV1021-0DA10-ZX95 drop into a panel specified around 3RV1011-0GA10?

Both are SIRIUS 3RV1 motor protection breakers with the same 45 mm width and DIN-rail snap-on mounting, so the footprint is identical. The key difference is the current rating — 3RV1021-0DA10-ZX95 is 0.32 A, while the 3RV1011-0GA10 is a different rating. Verify the motor FLA matches before substitution.

What compliance documentation does Siemens provide for 3RV1021-0DA10-ZX95?

RoHS compliance is documented with a substance prohibitance date of 01.05.2012. The part carries IP20 front protection and is designed for use on 35 mm DIN rail per EN 50022. Full IEC/UL certification details are available in the manufacturer's declaration of conformity.
