Product details

The Siemens 3RV2031-4SA15 is a SIRIUS motor-protection circuit breaker designed for a 14 A motor load at 400 V AC.

The 55 mm width occupies three standard 18 mm modular positions — plan your enclosure rail fill accordingly. Depth of 149 mm and height of 140 mm leave clearance for wiring ducts and adjacent devices. Any mounting position is permitted. Main contact terminals accept M6 ring lugs. The control circuit terminals accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded conductors — typical for a 14 A motor branch circuit.

Frequently asked questions

Where can I buy 3RV2031-4SA15 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 3RV2031-4SA15's breaking capacity at 400 V?

30 kA at 400 V AC. It also carries 100 kA at 240 V and 3 kA at 690 V. These are the maximum prospective fault currents the breaker can safely interrupt at those voltages.

What compliance documentation does Siemens provide for 3RV2031-4SA15?

As a SIRIUS product, the 3RV2031-4SA15 is designed to meet IEC 60947-2 and 60947-4-1 standards. The manufacturer provides a declaration of conformity covering CE, UKCA, and EAC. RoHS and REACH compliance declarations are available on request.
