The 20... 690 V rated voltage range covers standard low-voltage motor loads across global 400 V and 480 V networks. Dimensions are 55 mm wide, 140 mm high, 149 mm deep — a standard three-module footprint that fits most motor control center buckets. The screw-type terminals accept 2x (1... 25 mm²) or 1x (1... 35 mm²) solid or stranded copper, with M6 main contact bolts. Clearance requirements: 50 mm upwards, 50 mm downwards, 10 mm at the side — no extra gap needed at 240 V, but 125 mm at 400 V. ## Trip class and operating limits Class 20 trip means the breaker allows the motor to draw locked-rotor current for up to 20 seconds before tripping — standard for general-purpose induction motors driving pumps, fans, and conveyors. Maximum switching frequency is 15 operations per hour at AC-3 and AC-3e duty.","metaTitle":"Siemens 3RV2031-4EB10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2031-4EB10 SIRIUS motor protection circuit breaker, 32 A rated current, 30 kA breaking capacity at 400 V, Class 20 trip.
