The LX1FK240 is a replacement coil for Square D TeSys contactors requiring a 240 V AC control circuit at 40–400 Hz. It's a bare coil — no integrated suppressor module — so you'll need to handle snubbing externally if the application demands it. The inrush sits around 1100 VA at 0.9 power factor, dropping to 18 VA holding. That 18 W heat dissipation is real: factor it into your panel thermal budget if the contactor cycles continuously. Coil resistance: 44.5 Ω inrush, 1160 Ω holding — both quoted at 20 °C. Operating time is 100 to 170 ms for opening, 40 to 75 ms for closing. Keep ambient temperature between -5 and 55 °C. The inductance of the closed circuit is 5.75 H, which tells you something about the magnetic circuit design if you're doing any suppression calculations.","metaTitle":"LX1FK240 Square D TeSys Contactor Coil, 240 VAC, Obsolete","metaDescription":"Obsolete Square D LX1FK240 TeSys contactor coil, 240 VAC 40-400 Hz.
