The LX1FF264 is a replacement coil for TeSys F contactors, wound for 264 V AC at 50 Hz. It is a bare coil — no built-in suppressor module, so you add your own RC snubber or varistor across the terminals if the application demands it. Coil resistance measures 37.5 Ohm at 68 °F (20 °C); inrush power hits 550 VA at 50 Hz (cos φ 0.3), dropping to 45 VA holding. That 12-to-1 inrush-to-hold ratio is typical for an AC coil — the control transformer feeding it needs to handle the pick-up surge without drooping below 0.85 Uc. Closing time spans 23 to 35 ms; opening is faster at 5 to 15 ms.
For a BOM that needs this exact 264 V AC 50 Hz coil, the procurement path is a last-time-buy or a verified cross-reference from the TeSys F family.
Integration notes
Heat dissipation runs 12 to 16 W at 50 Hz — enough to matter inside a sealed enclosure. The coil sits on the TeSys F contactor frame; verify the mechanical interlock and auxiliary contact stack clear the coil profile before panel assembly. Drop-out threshold is 0.35 to 0.55 Uc at 131 °F (55 °C); operational range is 0.85 to 1.1 Uc. If the control transformer is shared with other AC coils, sequence the pick-up to avoid a cumulative voltage sag that keeps this coil from sealing.
