Control circuit is 1000 V AC 60 Hz, so this is for a 60 Hz panel (not 50 Hz line voltage). Closing time runs 23...35 ms, opening 5...15 ms, which puts it in the standard range for F-frame contactors. Coil holds in at 0.85...1.1 Uc and drops out at 0.35...0.55 Uc — that dropout margin means the contactor releases cleanly on a sag down to 350 V AC (on a 1000 V nominal line), which is generous for brownout ride-through. No built-in suppressor module, so you'll need an external RC snubber or varistor across the coil if driving it from a PLC output or solid-state relay; the coil's inductance of 48.9 H will generate a healthy kickback spike without one.","metaTitle":"TeSys LX1FF850 Contactor Coil, 1000 V AC 60 Hz, Active","metaDescription":"TeSys F contactor coil LX1FF850, 1000 V AC 60 Hz control circuit, 23-35 ms closing time, 10 Mcycles mechanical durability, active production.

If your panel runs 50 Hz or a different voltage, you'd need a different LX1FF variant — the coil family shares the same mechanical footprint, so swapping the coil alone changes the control voltage without replacing the contactor block."},{"question":"What compliance documentation is available for LX1FF850?","answer":"The part carries the TeSys range designation and is listed as a current-production component.
