It handles 7.5 kW at both 500 V and 690 V, with an AC-2 rating of 5.5 kW at 400 V and an AC-4 rating of 12.5 A at 400 V. That means it's built for squirrel-cage motors where the starting current is moderate (AC-2) or for reversing/inching duty where the contactor breaks full-load current (AC-4).
Main circuit connections use screw-type terminals accepting 2x (0.25 to 2.5 mm²) solid or 2x (1 to 6 mm²) stranded, up to 10 mm² max. AWG equivalents are 2x (16 to 12) solid and 2x (14 to 10) stranded. For short-circuit coordination, Type 1 requires a 63 A gL/gG fuse; Type 2 requires a 25 A gL/gG fuse. That's a key spec for panel builders — Type 2 keeps the contactor usable after a fault, Type 1 lets it be sacrificial.
