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.","metaTitle":"Siemens 3RV2031-4VA10-0BA0 SIRIUS Motor Protection CB, 35-45","metaDescription":"Siemens SIRIUS 3RV2031-4VA10-0BA0 motor starter protector, Class 10, 35-45 A thermal release, 650 A short-circuit release, size S2, screw terminals.

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.
