The Omron J7KC-12-10 24VDC is a 3-pole electrical contactor with a 24 VDC coil, part of the J7KC series. This is the part that closes the power circuit when the coil pulls in — sized for switching motor loads or resistive heating banks in a control panel.
The 24 VDC coil is the control voltage — common in PLC-driven panels where a 24 VDC power supply feeds the contactor directly. Verify the coil holds at the nominal 24 VDC and drops out below the pull-in threshold (typically around 18 VDC for this voltage class). The 3-pole configuration switches three phases, so it fits three-phase motor circuits or three-wire resistive loads.
