It's a DC low-consumption coil without a built-in suppressor module, so you'll need to add external suppression if the circuit demands it. Rated for 75 V DC control voltage, with operational limits of 0.85...1.1 Uc at 131 °F (55 °C) and a drop-out threshold of 0.2...0.35 Uc. That means it reliably picks up above about 64 V and drops out below roughly 26 V, which is a wide hysteresis — good for noisy DC supplies. Opening time is 45...60 ms, closing time 50...60 ms. This is a workhorse coil for high-cycle applications like conveyor or pump contactors. Inrush power is 1100 W at 68 °F (20 °C), dropping to 6 W holding power. The inrush resistance is 11.5 Ohm, holding resistance 2450 Ohm. Inductance of the closed circuit is 280 H — that's a high inductance, which limits inrush current once the magnetic circuit is closed. Operating temperature range is 23...131 °F (-5...55 °C). The coil technology is DC low consumption without a built-in suppressor module, so plan for external flyback diode or RC snubber if driving from a PLC output.","metaTitle":"TeSys LX4FK075 Contactor Coil, 75 V DC, Obsolete","metaDescription":"TeSys F LX4FK075 contactor coil, 75 V DC, DC low consumption.
