Product details

No ground fault detection here; that's handled separately if needed. Rated operating voltage spans 20 to 690 V AC, covering most industrial motor voltages from 208 V to 600 V. Interrupting capacity is substantial: 100 kA at 240 V, 30 kA at 400 V, 4 kA at 500 V, and 2 kA at 690 V. At 480 V it carries 52 A continuous, and at 600 V also 52 A. Motor horsepower ratings run from 5 hp at 110/120 V up to 50 hp at 575/600 V.

Width is 55 mm — a standard 3-module footprint for this class of motor-protective device. Depth is 149 mm, height 140 mm. Clearance requirements: 50 mm upwards, 50 mm downwards, 10 mm at the side — but at 400 V and above, the upward clearance jumps to 160 mm, at 500 V to 125 mm, at 690 V to 100 mm. At 240 V no additional clearance is needed. Terminal size is M6. That's enough for the 52 A rating with some headroom; a 50 mm² lug is comfortable.

Frequently asked questions

How do I get current pricing and availability for 3RV2031-4WA10?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through our independent distribution network — no automated price or count is displayed because the market moves daily on these breakers.

What is the closest functional second-source to 3RV2031-4WA10?

The 3RV2023-4DA10 is a smaller-frame sibling in the same SIRIUS family, but it does not drop into the same panel without rewiring. The 3RV2031-4WA10 has a 55 mm width and M6 terminals; the 3RV2023-4DA10 uses a narrower 45 mm body and smaller terminals, so bus-bar spacing and lug sizes differ. For a drop-in replacement on an existing 3RV2023-4DA10 layout, the 3RV2031-4WA10 will not fit without panel modifications.

What compliance documentation does this brand provide for 3RV2031-4WA10?

As a Siemens SIRIUS product, the 3RV2031-4WA10 carries CE marking for the European market and UL/CSA listing for North America. RoHS and REACH declarations are standard with the shipment. Specific certificate copies can be included with the RFQ response.
