Design Of The ProductFor motor protection

Product details

The Siemens SIRIUS 3RV2021-1GA10-ZW96 is a motor protection circuit breaker designed for Class 10 trip response — meaning it disconnects within 10 seconds at 7.2× the thermal setting, fast enough to protect standard induction motors from locked-rotor heating without nuisance tripping on start-up transients.

Integration Notes

Screw-type terminals on the main circuit accept 2x (1…2.5 mm²) solid or stranded, or 2x (2.5…10 mm²) — sized for standard motor feeder cables up to 10 mm² without lug adapters. Mounting position is any orientation; clearance above and below is 50 mm, zero at the sides and front/back — tight panel layouts work as long as the 50 mm vertical breathing zone is respected.

Frequently asked questions

Where can I buy 3RV2021-1GA10-ZW96 and how do I get a price?

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 difference between 3RV2021-1GA10-ZW96 and 3RV2021-1GA15?

Both are SIRIUS motor protection circuit breakers in the same 45 mm wide form factor with identical mounting and terminal specs. The -1GA15 carries a higher current setting range (typically 10–16 A vs the -1GA10's range) — the deciding factor is the motor full-load current your application needs.

Will 3RV2021-1GA10-ZW96 drop into a panel specified around 3RV2021-1GA15 without rewiring?

Yes — same 45 mm width, same DIN rail mounting, same screw terminal sizes. The footprint and wiring are identical; only the thermal setting range differs.

What compliance documentation is available for 3RV2021-1GA10-ZW96?

Standard Siemens SIRIUS documentation includes a CE declaration of conformity and the product is designed to meet IEC/EN 60947-2 and 60947-4-1. RoHS and REACH compliance declarations are available from Siemens upon request.
