The LX1FF910 is a replacement coil for TeSys F contactors, wound for 910 V AC 50 Hz control circuits. It is the energizing element that pulls the contactor in and holds it closed — no built-in suppressor module, so you add the RC snubber or varistor externally if the application demands it.
Coil inrush draws 550 VA at 50 Hz (cos φ 0.3), dropping to 45 VA once the contactor seals. That inrush-to-seal ratio is typical for AC-operated F-frame coils; the control transformer feeding it must be sized for the peak, not the hold-in. The coil operates between 0.85 and 1.1 Uc and drops out between 0.35 and 0.55 Uc at 131 °F (55 °C).
Schneider has marked the LX1FF910 as obsolete. There is no official direct successor order code in the TeSys F range for a 910 V AC 50 Hz coil.
