The 24 V AC coil keeps the control circuit isolated from the power side, standard for panel builders wiring through a PLC or relay output. Screw terminals accept up to 4 mm² stranded conductors; torque to 1.2 Nm per the manufacturer's spec. ## Integration Notes The 3NO main contacts handle the motor circuit; the integrated 1NO auxiliary contact provides feedback to the PLC or status lamp without an add-on block. Wire the coil from a 24 V AC control transformer — verify the transformer VA rating covers the inrush (typically 7–8 VA for this size). Screw terminals are standard for panel wiring; no special crimp tool needed beyond a screwdriver. If derating for ambient above 40 °C, reduce the 18 A continuous rating by 20% per the manufacturer's thermal curve.","metaTitle":"J7KN18D1024 Power Contactor, 3NO, 24V AC Coil, 18A, 7.5kW","metaDescription":"J7KN18D1024 power contactor from the J7KN series. 3-pole, 3NO main contacts, 24V AC coil, rated 18A switching current, 7.5kW at 400V AC.
