Coil for TeSys F contactors — 380-400 V AC line
The LX0FF010 is a replacement contactor coil from the Schneider Electric TeSys F range, designed for contactors in the F-frame family. It operates on a 380...400 V AC control circuit at 50/60 Hz, making it a direct fit for European-standard 400 V control panels where the coil is fed from the same bus as the motor power. Latching time is 35...40 ms; unlatching takes 50...100 ms. The coil resistance measures 114.1 Ω for the latching winding and 12447 Ω for the unlatching winding at 68 °F (20 °C). These values let you verify the coil against the contactor's published pick-up and drop-out curves without pulling the contactor from the panel.
These figures govern replacement intervals in high-duty-cycle applications like conveyor or pump cycling.
Integration notes
The coil mounts directly into the TeSys F contactor frame — no adapter plate or wiring harness modification needed. Control voltage limits are 0.85...1.1 Uc for both latching and unlatching, so the coil holds in reliably at 323 V AC (the lower limit) and tolerates line swell up to 440 V AC. Verify the control transformer tap before wiring.
