That 74 A translates to a 37 kW motor load at 400 V – the number a panel builder checks first when sizing a contactor for a pump or conveyor drive. Coil voltage is 230 V AC, so it lands directly on a standard control transformer secondary without a dropping resistor or interposing relay. ## Mounting and termination – DIN rail or screw, screw terminals Mounts on standard DIN rail or direct with screws – the same part covers both panel layouts. Screw terminals throughout; no push-in or spring-cage option on this variant. Wires up clean with ring or fork lugs torqued per the nameplate value. The 3NO main contacts handle the power legs; no auxiliary contact block is included in this order code, so add one if the PLC needs a feedback signal.","metaTitle":"Omron J7KN74230 Contactor, 3NO, 74 A, 230 V AC Coil","metaDescription":"Omron J7KN74230 contactor, 3-pole 3NO, 74 A AC-3 switching current, 230 V AC coil, 37 kW motor rating.
