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.","metaTitle":"Siemens 3RV2031-4SA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2031-4SA15 SIRIUS motor protection circuit breaker, 14 A rated current, 30 kA breaking capacity at 400 V AC.
