At 500 V the SCCR drops to 42 kA, and at 690 V it is 4 kA — still adequate for most 690 V industrial loads, but verify the available fault current at the point of installation. The motor horsepower ratings span 0.5 hp at 110/120 V up to 5 hp at 460/480 V, covering fractional through small integral-horsepower motors in a single frame size.
Clearance requirements: 50 mm above and below, 30 mm to the side, and zero clearance forward or backward — the zero forward clearance means it can sit flush against a panel backplate or busbar shield. Terminals accept 2x (0.75 to 2.5 mm²) solid or stranded, or 2x 4 mm² — sufficient for the motor branch circuit wiring typical at these ratings.
