Product details

Motor protection circuit breaker for harsh environments

The Siemens 3RV2031-4VA10-0BA0 is a SIRIUS 3RV2 motor starter protector in size S2, designed for motor protection with a Class 10 thermal overload release set at 35-45 A and a magnetic short-circuit release fixed at 650 A. Rated for ambient temperatures down to -50 °C, this unit is specified for cold-environment applications like refrigeration plants or outdoor pumping stations, though the 250 switching cycles at that extreme should be factored into maintenance intervals. The screw-terminal connection and standard switching capacity suit it for panel builds where a common DIN-rail mounted motor branch is needed. It integrates directly with SIRIUS contactors in a standard motor starter assembly, sharing the same footprint and bus system.

RoHS compliance is confirmed since October 2014. No SVHC declaration beyond that is triggered.

Frequently asked questions

What is the closest alternative to 3RV2031-4VA10-0BA0 in the same family?

Within the SIRIUS 3RV2 size S2 platform, the closest sibling would be a variant with a different thermal release band or short-circuit rating. The exact alternative depends on whether you need a higher or lower trip current — the 35-45 A band is specific to this order code. No direct pin-compatible substitute exists without changing the protection settings.
