At 400 V — the most common industrial supply — that 50 kA SCCR covers nearly any distribution panel downstream of a transformer. The 690 V rating is lower but still adequate for 690 V motor circuits with limited fault current. ## Terminals and wiring Main circuit terminals are screw-type box terminals. Solid wire: 2x (0.75... 16 mm²). Stranded: 2x (0.75... 25 mm²) or 1x (0.75 … 35 mm²). Fine-stranded with ferrule: 2x (0.75... 16 mm²) or 0.75... 25 mm². AWG equivalent for main contacts: 2x (18... 2) or 1x (18... 2). That range covers everything from control-circuit tails to motor feeder cable up to 35 mm². Auxiliary and control circuits use separate screw terminals. Dimensions: 55 mm wide, 140 mm high, 149 mm deep. Zero clearance needed at the sides or rear — backwards 0 mm, at the side 0 mm — so it tucks tight against other devices on the rail. Operating temperature: -50 to +60 °C. Shock rated at 25 g for 11 ms. Power dissipation at full load in hot state: 29 W total, 9.7 W per pole. That's warm but manageable in a ventilated enclosure; don't bury it next to a drive without some airflow.","metaTitle":"Siemens 3RV1031-4HA10-0BA0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1031-4HA10-0BA0 motor protection circuit breaker, 50 A continuous, 22 kW at 400 V, CLASS 10 trip, IP20 front.
