The Omron J7KN-10D-10 230 is a contactor from the J7KN series (Motor contactors from 4-500kW for normal and heavy-duty switching.). Omron describes it as: Contactor, 3-pole, 4 kW; 10 A AC3 (380-415 VAC) + 1 NO aux., 230 VAC.
A contactor is the switching element of a motor starter: the control circuit energises the coil and the main contacts connect the motor to the supply. Contactors wear with every start, so they are frequent maintenance parts.

Compatibility and replacement
Use the complete order code J7KN-10D-10 230 when ordering: in the Omron code the suffixes select output, connection, coil or supply voltage and cable length, so a part with a different suffix may not be a drop-in replacement.
Compare the label of the old unit with the technical data above (values taken from the official Omron product data); if anything differs, send us a photo and we will check it.
Replacement checklist
- AC-3 current / kW rating
- Coil voltage (AC or DC)
- Auxiliary contacts
