The LX9FH0652 is a specific contactor coil from the TeSys F range, designed to replace or service the coil assembly on a TeSys F contactor frame. It's a drop-in service part, not a standalone component — you're buying the electromagnet that pulls the contactor in. Rated for 65 V AC at 40-400 Hz, low-consumption type. That 65 V is the nominal pick-up voltage; the coil holds in at 85-110% of Uc and drops out between 35-55% of Uc, both at 55 °C. If your control transformer is feeding a nominal 65 V bus, this coil tracks it. If you're on a 48 V or 110 V control scheme, this isn't the one. Opening time is 25 ms, closing time 45 ms. That's fast enough for most motor starting and general switching duty on a line.
Coil characteristics and thermal budget
This coil draws 560-660 VA inrush at 20 °C, then settles to 8-10 VA holding. The inrush-to-hold ratio is steep — about 60:1 — which is typical for AC-operated contactor coils. The heat dissipation is 8.4 to 10.4 W once sealed. That's not trivial in a crowded panel; if you're grouping several TeSys F contactors side by side, factor that thermal load into your enclosure sizing or you'll cook the coil. Coil resistance: 5.99 ohms inrush at 20 °C, 127 ohms holding at 20 °C. No built-in suppressor module, so you'll need an external RC snubber or varistor across the coil if you're switching it with a PLC output or a solid-state relay — otherwise the inductive kickback will eat your driver. The 55 °C ceiling is the coil's limit, not the contactor's.
