The 690 V maximum rated value covers most industrial supply voltages, and the 50/60 Hz operating frequency matches standard line frequencies worldwide. The magnetic short-circuit release handles fault interruption without cascading upstream — the breaker is its own disconnecting means for the motor branch. Any mounting position is permitted. Dimensions: 55 mm wide, 140 mm high, 149 mm deep — fits standard panel cutouts. Clearance requirements: 50 mm upward, 140 mm forward, 30 mm to the side; no backward clearance needed. Screw-type box terminals on top and bottom accept 2×(0.75…25 mm²) solid/stranded or 1×(0.75…35 mm²). AWG equivalents: 2×(18…2) or 1×(18…2). Tightening torque 3…4.5 N·m. The S2 frame size keeps wiring straightforward for a 50 A branch. Operating temperature range -20…+60 °C, transport/storage -50…+80 °C. Relative humidity 10…95 %. Installation altitude up to 2 000 m. Shock resistance 25 g / 11 ms per IEC 60068-2-27. Surge voltage resistance 6 kV.","metaTitle":"Siemens 3RV5031-4HA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV5031-4HA10 SIRIUS motor protection circuit breaker, 50 A rated at 400 V AC-3, Trip Class 10, 690 V max, 3-pole, screw terminals, DIN rail mount.
