The J7KN14D10230 is a 3-pole power contactor from the J7KN series, with 3 normally-open main contacts and one normally-open auxiliary contact. It switches motor loads up to 14 A at 400 V AC, rated for 5.5 kW switching power and 10 HP. The 230 V AC coil pulls in reliably for standard line-voltage control circuits.
Mounts on a standard DIN rail in the control panel. Screw terminals accept solid or stranded copper conductors — strip length and torque per the manufacturer's label on the contactor body. The 3NO main contact arrangement suits three-phase motor starting or resistive load switching where all three phases need simultaneous make/break.
The 14 A switching current at 400 V AC is the AC-1 resistive load rating; for motor duty (AC-3), the contactor is sized for the 5.5 kW / 10 HP figure. The auxiliary 1NO contact provides a feedback or status signal back to the PLC or control relay without adding a separate auxiliary block.
