It operates on a 543 V DC control circuit — an uncommon voltage that narrows the pool of drop-in alternatives. The coil draws a steady-state current determined by its 51.9 Ohm resistance at 20 °C (68 °F) and 4.18 H inductance when the contactor is closed. That inductance means the coil holds well on DC but takes slightly longer to saturate than a lower-inductance design — expect a few extra milliseconds of pick-up delay compared to a standard 24 V DC coil. Rated for 10 million mechanical cycles at up to 3600 operations per hour at 60 °C (140 °F), this coil matches the LX1D6 contactor's mechanical endurance. The ambient operating range of -5 to 60 °C covers most panel environments, though sustained high temperature will accelerate insulation aging on the winding. ## Installation note — suppressor module The LX4D6WD ships without a built-in suppressor module. On a DC coil, that means the flyback diode or RC snubber must be added externally across the coil terminals — otherwise the inductive kick when de-energizing will arc across the control relay contacts and radiate noise into nearby electronics. A standard 1N4007 diode (reverse-biased across the coil) is adequate for this 543 V DC circuit, but verify the diode's reverse voltage rating exceeds the supply.","metaTitle":"Schneider Electric LX4D6WD TeSys contactor coil, 543 V DC","metaDescription":"Obsolete LX4D6WD coil for TeSys LX1D6 contactors. 543 V DC, 51.9 Ohm, 10 Mcycles.

Any alternative would require changing the control circuit voltage or replacing the entire LX1D6 contactor assembly. The only way to keep the existing contactor running is to source the LX4D6WD from remaining stock."},{"question":"What is the TeSys range and category for this part?","answer":"The LX4D6WD belongs to the Schneider Electric TeSys range, category 22341 — contactor accessories for D, K, and F frame contactors.
