The LX9FH0952 is a specific contactor coil from the TeSys F range, designed as a replacement or spare coil for TeSys F contactors. It operates on a 95 V AC control circuit at 40 to 400 Hz, with low-consumption coil technology. This coil does not include a built-in suppressor module, so you will need to add an external RC snubber or varistor across the coil terminals if your application requires suppression of switching transients — common on PLC-driven or electronic control circuits.
The coil draws 560 to 660 VA inrush at 68 °F (20 °C) across the 40-400 Hz range, dropping to 8 to 10 VA holding. That inrush figure tells you the momentary load on your control transformer when the contactor pulls in — make sure your 95 V AC supply can deliver that surge without dropping below the 0.85 Uc operational limit (80.75 V AC at 131 °F). Coil resistance measures 12.18 Ω inrush and 305 Ω holding at 68 °F (20 °C). The holding resistance is what determines steady-state current draw — roughly 0.31 A at 95 V AC — useful for sizing control circuit fusing. Heat dissipation runs 8.4 to 10.4 W. In a densely packed panel, that heat adds up; allow natural convection around the contactor or keep spacing per TeSys F guidelines. Opening time is 25 ms, closing time 45 ms. That 45 ms pull-in delay matters for sequencing logic — if you need faster response, this coil is not the pick.
Mechanical life and operating rate
That is one cycle per second — fine for most motor starting and general switching, but not for high-speed applications like rapid reversing or jogging duty.
