The LX0FK008 is a contactor coil from the TeSys F range, designed to replace or service the coil assembly in TeSys F contactors. It operates on a control circuit voltage of 220...230 V AC (50...400 Hz) or 220...230 V DC, with latching and unlatching voltage limits of 0.85...1.1 Uc. The coil's operating time is 50...100 ms for unlatching and 40...80 ms for latching. Average resistance at 68 °F (20 °C) is 28.81 Ohm for latching and 3733 Ohm for unlatching.
The 220...230 V AC/DC control voltage covers both common industrial control voltages in a single coil — useful for panels that run mixed AC and DC control circuits. The AC tolerance from 50 to 400 Hz means it works on standard 50/60 Hz supplies as well as higher-frequency applications like 400 Hz aircraft ground power. The 1 Mcycles mechanical durability is typical for contactor coils in this class; it will outlast most electromechanical contactor bodies in cyclic service. The maximum operating rate of 120 cycles per hour at 104 °F (40 °C) is a thermal limit — exceeding it risks overheating the coil. For high-duty-cycle applications like rapid reversing or jogging, derate or look at a coil rated for higher switching frequency. The operating time (50...100 ms unlatching, 40...80 ms latching) is fast enough for general motor starting but not for precision timing circuits.
