It operates on a 125 V DC control circuit and is the service part you order when the original coil fails or a panel spec changes voltage. ## Key electrical characteristics The coil pulls in at 2100 W inrush at 20 °C, then holds at 10 W — the inrush resistance is 3.73 Ohm, holding resistance 916 Ohm. That wide ratio means the DC supply must deliver the inrush peak without droop; a marginal power supply can cause chatter on pickup. Control voltage limits are 0.85...1.1 Uc for operation and 0.2...0.35 Uc for drop-out at 55 °C. So at 125 V DC nominal, the coil drops out between 25 V and 44 V — useful to know if you have a long DC run with voltage drop. The closed-circuit inductance is 122 H, which combined with the holding resistance gives the low holding power. No built-in suppressor module is included, so you need an external flyback diode or RC snubber across the coil to protect the DC control circuit from the inductive kick. ## Mechanical and thermal limits The ambient temperature range for operation is -5 to 55 °C. These are the limits that govern replacement intervals in high-cycle applications like packaging or conveyor sortation. Opening time is 45...60 ms, closing time 50...60 ms. That timing matters when coordinating with upstream protection or sequencing multiple contactors in a motor control center.","metaTitle":"TeSys LX4FK065 Contactor Coil, 125 V DC, Active","metaDescription":"TeSys F LX4FK065 replacement contactor coil for LX1FK contactors. 125 V DC control, 45-60 ms opening.
