It accepts a control voltage of 380...415 V AC (40...400 Hz) or 380...415 V DC, making it suitable for both AC and DC control circuits in industrial panels. This coil draws 550 VA inrush power at 68 °F (20 °C) and settles to 31 VA holding power, with a closed-circuit inductance of 12 H. The average resistance measures 274 Ω inrush and 2075 Ω holding at the same temperature, so the coil's DC resistance climbs sharply once the armature seals. Operating time is 60 ms opening and 50 ms closing, with a maximum operating rate of 3600 cycles per hour at 158 °F (70 °C). Heat dissipation ranges from 15 to 18.3 W, which matters for enclosure thermal budgeting — especially if multiple contactors are ganged in a sealed cabinet. The coil has no built-in suppressor module, so you will need to add an external RC snubber or varistor across the coil terminals if driving it from a PLC output or solid-state relay. Control voltage limits are 0.85...1.1 Uc for operation at 131 °F (55 °C) and 0.3...0.5 Uc for drop-out at the same temperature. Ambient air temperature for operation spans -5 to 55 °C (23...131 °F). The coil mounts directly onto the TeSys F contactor frame — no adapter bracket needed. Verify the coil's pole-face alignment with the contactor armature before tightening the retaining clip; a mis-seated coil increases air gap and can cause audible hum or premature dropout. Because this is a low-consumption coil (31 VA hold), it generates less heat than standard TeSys F coils, which helps keep panel ambient temperature down in dense layouts. The AC/DC compatibility simplifies wiring in mixed-control-voltage panels.","metaTitle":"TeSys LX9FK936 Contactor Coil, 380-415V AC/DC, Obsolete","metaDescription":"TeSys F LX9FK936 specific contactor coil, 380-415V AC/DC, 550 VA inrush, 31 VA hold.
