It is a DC low-consumption coil without a built-in suppressor module, so you will need to add a free-wheeling diode or RC snubber across the coil terminals if the driving PLC or relay card does not already handle flyback suppression. The coil draws 750 W inrush at 20 °C (about 2 A peak) and settles to 5 W holding. The holding resistance is 44 kΩ, which means the steady-state current is around 8.5 mA — low enough that a standard 24 V DC relay output can drive it through a series resistor or a dedicated DC coil driver, but the inrush spike needs a supply that can deliver the peak without droop. ## Timing and mechanical life Closing time is 40 to 50 ms; opening takes 40 to 65 ms. That spread matters if you are coordinating with upstream short-circuit protection or sequencing multiple contactors — the opening scatter can be 25 ms, so do not rely on this coil alone for precise simultaneous break. Maximum operating rate is 2400 cycles per hour at 55 °C. That is one cycle every 1.5 seconds — fine for most motor starting and resistive load switching, but if you are running a rapid-pick-and-place or a fast-reversing application, you will need to check the thermal rise in the coil. ## Voltage tolerance and temperature range The coil holds in from 0.85 to 1.1 times the rated control voltage (319 to 412 V DC) at 55 °C. Drop-out occurs between 0.15 and 0.2 Uc (56 to 75 V DC). That wide drop-out margin means the contactor will not chatter on a sagging DC bus — it stays pulled in until the voltage falls well below the nominal rail.","metaTitle":"TeSys LX4FH375 Contactor Coil, 375 V DC, Active","metaDescription":"TeSys F LX4FH375 contactor coil, 375 V DC control voltage, active lifecycle. 10 Mcycles mechanical durability, 40-50 ms closing time.

The closest alternative would be a different voltage coil (e.g., LX4FH220 for 220 V DC or LX4FH440 for 440 V DC) — but those are not pin-compatible substitutes; the coil voltage must match the control circuit.
