The LX1FL1106 is a replacement contactor coil from the Schneider TeSys F range, designed to energize the contactor's electromagnet and pull in the main power contacts. It operates on an AC control circuit at 50/60 Hz, with a rated control voltage of 100 V AC at 50 Hz and 100...110 V AC at 60 Hz. This coil is specified without a built-in suppressor module, meaning an external RC snubber or varistor must be added across the coil terminals if the control circuit requires transient suppression — common practice when the contactor is driven by a PLC output or electronic relay.
What to watch when fitting this coil
The LX1FL1106 is the coil-only component for a TeSys F contactor frame. It mounts onto the contactor's magnet assembly via the standard clip or screw retention — no special tools, but the contactor must be de-energized and the arc chamber removed for access. Verify the coil's AC voltage rating matches the control transformer tap before installation; a 100 V AC coil on a 110 V line will overheat and fail prematurely. Because this coil lacks a built-in suppressor, the installer must add an external RC network (e.g., Schneider part number RXZ RCP or equivalent) across the A1-A2 terminals if the control signal comes from a solid-state output. Without suppression, the inductive kickback from coil de-energization can weld relay contacts or damage the PLC driver.
