It runs on a 440 V AC 50/60 Hz control circuit, with latching time of 35 to 40 ms and unlatching time of 50 to 100 ms. The 440 V AC control voltage is the nominal coil rating — the circuit supplying the coil must deliver this voltage within the latching limits of 0.85 to 1.1 Uc (374 to 484 V AC) and unlatching limits of 0.85 to 1.1 Uc. Coil resistance measures 118.7 Ω for the latching winding and 10,802 Ω for the unlatching winding at 20 °C, which governs inrush and hold current draw from the control transformer. This suits intermittent-duty applications like conveyor start/stop or pump cycling, not continuous high-speed switching. ## Where this class of part is used Contactor coils like the LX0FF012 are the replaceable actuation element inside TeSys F contactors, which switch motor loads, resistive heaters, and other power circuits in industrial control panels. The coil itself mounts onto the contactor's magnet assembly and is swapped when the winding fails or the control voltage needs changing.","metaTitle":"TeSys LX0FF012 Contactor Coil, 440 V AC, Obsolete","metaDescription":"TeSys F LX0FF012 contactor coil, 440 V AC 50/60 Hz control circuit.
