It is a replacement coil for TeSys D and K contactors that use a 220 V DC coil, meaning it directly swaps into the existing contactor assembly without modifying the panel wiring. This part is officially obsolete per the manufacturer's lifecycle status. A parametric search for a 220 V DC contactor coil in the TeSys range is the practical next step. ## What the 220 V DC rating means for fit The 220 V DC control circuit voltage is the coil's nominal operating voltage. Applying AC or a different DC voltage will either fail to pull the contactor in or damage the coil winding. In a panel, this coil is typically wired to a 220 V DC power supply derived from a rectified AC bus or a dedicated DC source. Verify the supply polarity — DC coils are polarity-sensitive and may include built-in suppression diodes that dictate the wiring direction.","metaTitle":"TeSys LX4D4MD Contactor Coil, 220 V DC, Obsolete","metaDescription":"TeSys LX4D4MD contactor coil, 220 V DC control circuit voltage.
