The LX9FF300 is a specific replacement coil for the TeSys F contactor range, rated 300 V AC at 40 to 400 Hz with low-hold consumption. It is the part that pulls the contactor in and keeps it sealed — no built-in suppressor, so you add the RC snubber or varistor externally per the panel design. Opening time is 130 ms, closing time 35 ms. The coil draws 690 to 855 VA inrush, then drops to 6.6 to 8.1 VA holding. Average resistance measures 114.1 Ω inrush and 4098 Ω holding at 20 °C. Heat dissipation runs 5.9 to 7.2 W once sealed. The control voltage limits are 0.85 to 1.1 Uc for pickup and 0.35 to 0.55 Uc for dropout at 55 °C.
Sourcing reality — obsolete, sourced to order
If you are filling a BOM line or replacing a failed coil in a live panel, the RFQ is the correct next step.
