The 24 V AC coil makes it a direct fit for control transformers or PLC relay outputs in standard industrial panels. DIN rail mounting and screw terminals mean it clips into the same footprint as other compact contactors in the 9 A class — no surprise when you're laying out a crowded enclosure. The 9 A switching current at 400 V AC (4 kW) is the AC-1 resistive load rating — the contactor handles motor starting or general switching within that envelope. The 4NO contact configuration gives you four independent normally-open poles, useful for switching multiple loads or phases in a single device. The 24 V AC coil draws from a common control voltage in industrial panels; verify your control transformer can supply the inrush if you're ganging several contactors on one circuit. ## Panel integration The compact 4-pole body saves rail space compared to stacking two 2-pole contactors.","metaTitle":"J7KNA09424 Miniature Contactor, 4NO 24V 9A 4kW DIN Rail","metaDescription":"J7KNA09424 miniature contactor from the J7KNA series: 4-pole, 4NO, 24 V AC coil, 9 A switching current, 4 kW at 400 V AC.
