The Schneider LX1FJ1000 is a TeSys F contactor coil rated for 1000 V AC control circuits at 40...400 Hz. It's the replaceable coil assembly for a TeSys F frame contactor — the electromagnet that pulls the main contacts in when energized. Opening time runs 100...170 ms, closing 40...75 ms, so the mechanical response is on the slower side for a contactor this size; that matters if you're sequencing multiple contactors in a transfer scheme and need to guarantee break-before-make timing.
Coil electrical characteristics
The coil draws 1075 VA inrush at 68 °F (20 °C) and holds at 15 VA with a cos φ of 0.3. Average DC resistance is 720 Ω inrush and 19420 Ω holding at the same temperature. Heat dissipation is 14 W across the 40...400 Hz range — that's the heat the coil dumps into the contactor enclosure, so factor it into your panel thermal budget if you're running this in a sealed cabinet. The coil has no built-in suppressor module, so you'll need an external RC snubber or varistor across the terminals if the control circuit drives inductive loads nearby.
The LX1FJ coil snaps into the TeSys F contactor frame — no tools needed for the coil change, just a screwdriver to release the retaining clip. The control circuit voltage limits are 0.85...1.1 Uc for pickup and 0.3...0.5 Uc for drop-out at 131 °F (55 °C), so it holds in down to 850 V AC and drops out reliably below 500 V AC. Ambient operating range is -5...55 °C. The inductance of the closed circuit is 84.6 H, which is high enough that the back-EMF on de-energization can arc across un-suppressed contacts — again, fit that external suppressor.
