The Square D LX1FK380 is a TeSys series contactor coil rated for 380-400 V AC control circuits at 40-400 Hz. It provides the electromagnetic force to switch the contactor, drawing 1100 VA inrush at 20 °C and 18 VA holding. Without a built-in suppressor module, external RC snubbing or varistor protection must be added for inductive load switching. Opening time is 100-170 ms, closing time 40-75 ms.
