The LX1FJ080 is a replacement contactor coil from the TeSys F range, designed for 80 V AC control circuits at 50/60 Hz. It is the drop-in energizing component for TeSys F contactors — when the original coil fails or a panel needs a different control voltage, this is the part that swaps in without changing the contactor base.
A 24 V DC or 230 V AC coil will not pull in on this voltage. The AC 50/60 Hz designation means it is designed for alternating current at standard line frequencies; do not use on a DC control bus or a variable-frequency drive output.
