For AC-4 duty — inching, jogging, plugging — the contactor is rated 8.5 A at 400 V, which is the figure to watch if your application cycles the motor under load. The auxiliary circuit handles 10 A at 24 V (AC-12), so it can drive a modest PLC input or relay load directly. The coil draws 0.8 to 1.1 A at 60 Hz, which matters when sizing the control transformer. Screw terminals on both main and auxiliary circuits accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid/stranded, with a maximum of 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16) and 2x (18 to 14), with a single 12 AWG allowed. That covers most panel wiring without needing ferrules. Side-by-side mounting is allowed, so no derating for zero-gap installation.
For type 2 coordination (contactor remains operational after a fault), the fuse must be gL/gG 20 A. This is the spec your panel designer needs for the short-circuit rating.
