The LX4FG140 is a replacement contactor coil from the Schneider Electric TeSys range, part of the 18401-World Service Parts category. It is designed for DC wide-range control circuits and operates at a nominal 140 V DC, with an operational voltage window of 0.85...1.1 Uc at 131 °F (55 °C) and a drop-out threshold of 0.15...0.2 Uc. Coil resistance measures 24.3 Ohm inrush and 4958 Ohm holding at 68 °F (20 °C). The coil is supplied without a built-in suppressor module, so you will need to add external suppression if the application demands it — common on DC-switched inductive loads to protect the control contacts.
The 140 V DC control voltage is specific — not a common 24 V or 110 V DC coil. If your panel runs a 140 V DC control bus, this coil is a direct drop-in. The operating time of 30...40 ms closing and 30...50 ms opening is typical for a contactor coil of this size; it means the main contactor will pull in and drop out within that window, which matters for sequencing logic in a motor starter or transfer scheme.
