Product details

Motor protection circuit breaker, CLASS 10 trip, 30 kA SCCR

The Siemens SIRIUS 3RV2031-4WA10-ZX95 is a motor protection circuit breaker designed for Class 10 trip response — it opens within 10 seconds at 7.2× the thermal setting, which keeps the motor winding below damage threshold during a locked-rotor event.

Dimensions are 55 mm wide, 140 mm tall, 149 mm deep. The 55 mm width is a three-module footprint on the rail — plan for that slot count when laying out a multi-breaker panel. Any mounting position is acceptable.

Screw-type terminals on the main circuit accept 2×(1–35 mm²) or 1×(1–50 mm²) solid or stranded copper. Torque spec for the M6 main contact screws — standard for this current class. The terminals are sized for the 52 A continuous rating at 480/600 V.

Environmental range

Temperature compensation is active across the full operating range. Rated voltage covers 20–690 V.

Frequently asked questions

Where can I buy 3RV2031-4WA10-ZX95 and 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 closest functional second-source to 3RV2031-4WA10-ZX95?

The closest peer in the SIRIUS line is 3RV2021-4NA25, which shares the same CLASS 10 trip class and DIN-rail mounting but has a lower breaking capacity and different terminal sizing. Verify the fault current requirements and wire range before substituting.

What is the depth of 3RV2031-4WA10-ZX95?

The depth is 149 mm. Combined with the 55 mm width and 140 mm height, plan for a three-module DIN-rail slot with 50 mm clearance above and below.

What compliance documentation does this part carry?

The evidence does not list specific certifications (UL, CSA, CE, RoHS, REACH) for this order code. Compliance documentation is typically available from the manufacturer upon request for the SIRIUS series.
