At 400 V AC the unit interrupts 30 kA (Icu per IEC 60947-2). At 240 V AC that figure rises to 50 kA. For higher fault currents, the manufacturer specifies upstream gG fuse coordination: 125 A at 400 V, 100 A at 500 V, 80 A at 690 V. This lets the panel designer size the branch protection without over-fusing the feeder. Any mounting position is permitted. The S2 frame (55 mm wide, 140 mm tall, 149 mm deep) fits standard motor starter combos alongside a contactor on the same rail. ## Environmental and operational range Rated for operation from -50 °C to +60 °C, with temperature compensation active between -20 °C and +60 °C. Storage and transport range extends to -50 °C to +80 °C. Maximum switching frequency in AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV2031-4EB10-0BA0 SIRIUS Motor Protection CB, 30 kA","metaDescription":"Siemens SIRIUS 3RV2031-4EB10-0BA0 motor protection circuit breaker, size S2, Trip Class 20, 30 kA breaking capacity at 400 V AC.
