The LX9FL929 is a specific replacement coil for TeSys F contactors, carrying a 169 to 186 V DC control circuit voltage. This is a low-consumption variant, meaning the hold-in power draw settles at 48 W at 68 °F (20 °C) after the inrush peak of 733 W at the same temperature. The coil is supplied without a built-in suppressor module, so you will need to fit an external RC snubber or free-wheeling diode across the terminals if the control circuit drives inductive loads that could cause back-EMF spikes.
Switching times and thermal budget
Opening time is rated at 60 ms, closing at 20 ms — fast enough for most motor-start and isolation sequences in a panel. Heat dissipation runs between 22.8 and 27.8 W, so factor that into the enclosure's thermal rise calculation; a densely packed cabinet may need forced ventilation or a larger panel to stay within the -5 to 55 °C ambient operating range.
