74 A AC-3 contactor for motor loads
The Omron J7KN7424D is a 3-pole contactor rated for 74 A AC-3 switching current — that's the current it can make and break under motor-start duty, not just carry continuously. At 690 V it handles 37 kW, which covers a 50 HP motor at typical line voltages. The 24 VDC coil is standard for PLC-controlled panels; the screw terminals keep wiring straightforward for panel builders and MRO techs alike.
Panel fit and mounting options
Mounts on DIN rail or directly with screws — the DIN rail option speeds panel assembly and replacement; the screw mount is handy when the rail is full or the panel layout calls for fixed positioning. The 3NO contact configuration is the standard for three-phase motor circuits; no auxiliary contacts onboard, so plan for a separate block if you need N.C. feedback or status indication.
