The headline motor ratings are 4.5 kW at 500 V and 5.5 kW at 690 V — these are the AC-3 duty figures that govern switching of standard squirrel-cage induction motors. For reversing or inching duty (AC-4), the contactor is rated 8.5 A at 400 V, which is the figure you size for plugging or jogging cycles where the contacts break full load current. Coordination is defined: Type 1 coordination requires a 35 A gL/gG fuse; Type 2 coordination (lower let-through for reduced contact damage) requires a 20 A gL/gG fuse. This lets the panel builder select the right upstream protection without guesswork. The screw-type terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded conductors, with AWG equivalents of 2x (20 to 16), 2x (18 to 14), and 1x 12. That covers the typical motor-circuit wire sizes for this frame.
DIN rail integration and environmental limits
The 45 x 57.5 x 72 mm envelope (width, height, depth) and side-by-side mounting capability mean you can pack multiple contactors on a single rail segment.
