The LX0FK011 is a replacement contactor coil from the TeSys F range, designed to drive the main contactor in a motor starter or switching assembly. It operates on a 415 V AC 50/60 Hz control circuit, with the latching coil drawing 112.06 Ohm and the unlatching coil measuring 13256 Ohm at 68 °F (20 °C). This is a service part — category 18401-WORLD SERVICE PARTS(CTR ACCESS) — meaning it is stocked as a critical spare for installed TeSys F contactors. If you have a TeSys F contactor with a failed coil, this is the direct drop-in replacement.
The control circuit voltage is 415 V AC 50/60 Hz, with voltage limits of 0.85 to 1.1 Uc for both latching and unlatching. That means the coil will reliably pick up and drop out between roughly 353 V and 457 V — important when sourcing from a line that may sag under load. Operating time is 50 to 100 ms unlatching and 40 to 80 ms latching. For a contactor coil, this is standard — the unlatching time is the dropout delay, which governs how fast the main contacts open on a control signal loss. If your safety circuit timing relies on a faster dropout, verify this window against your requirements. At 120 cyc/h, that is one operation every 30 seconds — adequate for most motor starting duty, but not for high-speed jogging or rapid cycling applications.
