Product details

The Siemens SIRIUS 3RV1021-4DA10-ZW98 is a 3-pole motor protection circuit breaker rated at 25 A continuous current and 11 kW at 400 V AC-3, with a breaking capacity of 50 kA at 400 V. The screw-type terminals accept solid or stranded conductors: 2x (1...2.5 mm²) and 2x (2.5...6 mm²) per pole, with AWG equivalents of 2x (14...10). Zero clearance is required at the back and sides — 0 mm backwards and 0 mm at the side — so it can be packed tight against adjacent devices on the rail without derating.

The auxiliary switch option (product extension auxiliary switch: Yes) means you can add a remote status contact without extra wiring to the main circuit. The 25 A continuous rating and 11 kW motor rating make it a direct fit for motor branch circuits feeding pumps, fans, or small conveyors up to that power level.

Frequently asked questions

Where can I buy 3RV1021-4DA10-ZW98?

This part is sourced and quoted to order against an RFQ through our independent distribution channel; availability and current pricing are confirmed at quote time.

What is the breaking capacity of 3RV1021-4DA10-ZW98 at 400 V?

The breaking capacity at 400 V AC is 50 kA, which is the fault current it can safely interrupt at that voltage level.

What is the difference between 3RV1021-4DA10-ZW98 and 3RV6021-4DA10?

The 3RV6021-4DA10 is a functionally similar motor protection circuit breaker from the same SIRIUS family, but the 3RV1021 series is the standard industrial version; the 3RV6021 is a different variant with potentially different accessories or approvals. Both share the same 25 A / 11 kW / Class 10 footprint, but verify the specific auxiliary contact and terminal configuration for your panel before substituting.

What compliance documentation does Siemens provide for 3RV1021-4DA10-ZW98?

The part carries a substance prohibitance date of 01.05.2012, indicating compliance with RoHS and REACH requirements. Standard Siemens documentation includes a CE declaration, UL/CSA recognition, and IEC 60947-2/4 certification — all available through the manufacturer's support portal.
