It operates on 165 V DC control voltage with a low-consumption DC circuit, drawing 24.2 Ω inrush resistance and 6240 Ω holding resistance at 20 °C. Opening time is 45...60 ms, closing time 50...60 ms — a standard response for this class of contactor coil, suitable for motor switching and general load control in industrial panels. The coil lacks a built-in suppressor module, so an external flyback diode or RC snubber should be added across the coil terminals to protect the control circuit from voltage spikes during de-energization. ## Control voltage and limits Rated control voltage is 165 V DC. Operational range is 0.85...1.1 Uc at 55 °C; drop-out occurs at 0.2...0.35 Uc at the same temperature.","metaTitle":"TeSys LX4FJ165 Contactor Coil, 165 V DC, Obsolete","metaDescription":"TeSys LX4FJ165 contactor coil, 165 V DC, DC low consumption.
