The LX9FG170 is a specific contactor coil from the TeSys F range, designed for 170 V AC control circuits at 40 to 400 Hz, low-consumption type. It is a replacement coil for TeSys F contactors, not a standalone contactor — it mounts onto the contactor's magnet system to energize the main poles. Rated control voltage is 170 V AC; the coil operates between 0.85 and 1.1 Uc at 131 °F (55 °C) and drops out between 0.35 and 0.55 Uc. Opening time is 130 ms, closing time 35 ms — the slower opening is typical for AC coils without a suppression module, which this coil lacks.
Inrush power draw is 950 to 1180 VA at 40 to 400 Hz (at 68 °F / 20 °C), dropping to 8.9 to 10.9 VA holding — the inrush spike matters for transformer sizing in the control circuit. Coil resistance is 26.27 ohms inrush and 1081 ohms holding at 68 °F (20 °C) — the holding resistance is roughly 40× the inrush, confirming the low-consumption design. Heat dissipation ranges from 8 to 9.8 W — enough to consider ventilation if multiple coils are ganged in a small enclosure. Ambient operating temperature range is 23 to 131 °F (-5 to 55 °C) — standard for indoor panel installation, not rated for extreme cold or high-heat environments.
This coil is a direct replacement for the TeSys F contactor range — it clips onto the contactor's magnet yoke and connects to the control circuit via the coil terminals. No built-in suppressor module means an external RC snubber or varistor should be added across the coil if driving from a PLC output or if EMI suppression is required.
