That 7.5 kW figure at 400 V tells you the motor size it's sized for — a standard 7.5 kW four-pole induction motor on a 400 V three-phase line. The Class 10 trip means it will clear a stalled-rotor condition within 10 seconds at seven times the thermal setting, which is the standard protection for standard squirrel-cage motors. It includes phase failure detection as standard, so if one phase drops, the breaker trips before the motor single-phases and burns out. At 240 V AC it handles 100 kA, at 500 V AC it's 12 kA, and at 690 V AC it drops to 5 kA — so if your panel's available fault current exceeds those numbers at the respective voltage, you need to coordinate with a backup fuse or a higher-rated breaker upstream. ## Mounting and wiring — DIN rail, screw terminals, IP20 front Zero mm clearance required at the back and at the sides — you can butt it against the enclosure wall or adjacent devices without derating for airflow blockage. Main circuit terminals are screw-type with box terminals, accepting stranded wire from 0.75 mm² up to 35 mm² for a single conductor, or 2x 25 mm² for two conductors. Solid wire acceptance is 2x 0.5 to 1.5 mm² or 2x 0.75 to 2.5 mm². The auxiliary and control circuit terminals are also screw-type. Dimensions are 55 mm wide, 140 mm high, 149 mm deep — the depth is the dimension that sticks out from the DIN rail, so if your enclosure depth is tight, that 149 mm is the number to check against the door clearance. ## Lifecycle and sourcing — current production, quoted to order ## Duty cycle and thermal dissipation — 15 ops/h AC-3, 14.5 W heat loss Maximum operating frequency in AC-3 duty is 15 operations per hour. That's the switching limit for motor starting under load — if your application cycles faster than every four minutes, this breaker will overheat the bimetal strip and nuisance-trip. The power dissipation in hot operating state is 14.5 W at rated current, which is the heat it dumps into the enclosure. For a panel with multiple breakers ganged together, sum those 14.5 W per unit and check the enclosure's thermal rise.","metaTitle":"Siemens 3RV1031-4AA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1031-4AA15 SIRIUS motor protection circuit breaker, 16 A continuous, Class 10 trip, 7.5 kW at 400 V AC-3, 50 kA breaking capacity at 400 V.
