It operates on a 45 V DC control circuit, with closing time between 30 and 40 ms and opening between 30 and 50 ms — a tight window that matters when coordinating interlocking or safety circuits on the same panel. The coil draws an inrush resistance of 3.45 Ω at 68 °F (20 °C), dropping to 621.7 Ω in the holding state. Dropout occurs between 0.15 and 0.2 Uc at 131 °F (55 °C).","metaTitle":"TeSys LX4FF045 Contactor Coil, 45 V DC, Active Production","metaDescription":"TeSys LX4FF045 contactor coil, 45 V DC control voltage, 30-50 ms operating time, active production.
