The 3RV2032-4VA10 carries a 100 kA breaking capacity at 240 V and 50 kA at 400 V. The rated voltage range is 20 to 690 V, so it covers 400 V three-phase and 480 V systems common in North American industrial panels. Horsepower ratings: 10 hp at 230 V, 15 hp at 200/208 V, 40 hp at 460/480 V, and 50 hp at 575/600 V. The 45 A continuous rating at 480 V and 600 V gives the steady-state current the breaker will carry without tripping — match this to the motor FLA, not the horsepower nameplate alone.
Mounting and wiring — panel integration
Any mounting position is allowed. Clearance requirements: 50 mm upwards, 50 mm downwards, 10 mm at the side — but at 240 V no clearance is required, so in a 240 V panel you can pack it tighter. At 400 V you need 125 mm upwards, at 500 V 100 mm, at 690 V 80 mm. That upward clearance is for arc flash venting; don't skip it on higher-voltage builds. Main circuit terminals are screw-type, accepting 2× (1 to 35 mm²) or 1× (1 to 50 mm²) solid or stranded copper. Terminal size is M6. The 55 mm width and 140 mm height with 149 mm depth mean it occupies a standard three-module-wide footprint on the DIN rail — plan for that in your enclosure fill factor.
