Product details

The Siemens SIRIUS 3RV1021-0GA10-ZW96 is a 3-pole motor protection circuit breaker rated for 0.63 A continuous current with Trip Class 10 thermal overload protection. It delivers 100 kA breaking capacity across 240 V to 690 V AC, making it suitable for high-fault-current industrial panels.

The 0.63 A continuous current rating and 0.18 kW motor rating at 400 V AC size this breaker for small fractional-horsepower motors — think coolant pumps, small fans, or conveyor drives under 0.25 kW. That SCCR headroom simplifies panel coordination in high-capacity distribution boards.

The 45 mm width matches standard SIRIUS 3RV1 compact breaker spacing, so it fits existing panel layouts without re-drilling.

Frequently asked questions

Where can I buy 3RV1021-0GA10-ZW96 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the closest functional second-source to 3RV1021-0GA10-ZW96?

The 3RV1011-0GA10 is a smaller-frame sibling in the same SIRIUS family, but it carries a lower breaking capacity and different trip curve. The 3RV1021-0GA10-ZW96 is the correct drop-in for a panel designed around the 3RV1021 frame — verify the 3RV1011's SCCR rating before substituting.

What compliance documentation does this breaker carry?

The part carries a substance prohibitance date of 01.05.2012, indicating RoHS compliance. As a Siemens SIRIUS product, it meets IEC/EN 60947-2 and 60947-4-1 standards. Specific UL/CSA certification details should be confirmed from the nameplate or manufacturer documentation.
