The LX0FF007 is a contactor coil from the Schneider Electric TeSys F range, designed to actuate the main contactor armature in TeSys F contactor assemblies. It operates on a 127 V control circuit, accepting both AC (50...400 Hz) and DC supply, making it flexible for panels with mixed control voltage sources.
Key electrical characteristics
Latching time is 35...40 ms, unlatching 50...100 ms. Coil resistance measures 11.61 Ω for the latching winding and 1788 Ω for the unlatching winding at 68 °F (20 °C). The high unlatching resistance indicates a separate hold-in winding or a pulse-operated unlatch circuit — common in TeSys F mechanically latched contactors where the unlatch coil only needs a brief pulse to release the armature.
Mechanical ratings and duty cycle
This duty cycle suits intermittent switching applications like conveyor start/stop or pump cycling, but not high-speed repetitive operations where a higher-rated coil would be needed.
