It is designed to operate a TeSys contactor when energized with 300 V DC, making it a service part for existing panel installations rather than a new-design component. Operating time is specified at 100 to 130 ms for opening and 70 to 80 ms for closing, which governs the switching sequence in the contactor it drives. The coil uses DC low-consumption technology and comes without a built-in suppressor module, so you will need to add external flyback suppression (a free-wheeling diode) across the coil terminals to protect the control circuit from inductive kickback. ## Control voltage and operating limits Rated control circuit voltage is 300 V DC (Uc). Operational limits are 0.85 to 1.1 times Uc at 131 °F (55 °C). Drop-out occurs between 0.2 and 0.4 times Uc at the same temperature. Ambient operating temperature range is 23 to 131 °F (-5 to 55 °C).","metaTitle":"Schneider Electric LX4FX300 TeSys contactor coil, 300 V DC","metaDescription":"Active-production TeSys FX contactor coil, 300 V DC control voltage, 100-130 ms opening time.
