The LX4FG022 is a contactor coil from the Schneider Electric TeSys range, designed as a replacement coil for TeSys F contactors. It operates on a 22 V DC control circuit using DC wide range technology.
Rated control circuit voltage is 22 V DC, with operational limits of 0.85...1.1 Uc at 131 °F (55 °C) and drop-out at 0.15...0.2 Uc. That means the coil picks up reliably between about 18.7 V and 24.2 V DC, and drops out cleanly between 3.3 V and 4.4 V DC — important for control logic that needs to guarantee de-energization on undervoltage. Closing time is 30...40 ms, opening time 30...50 ms. This is standard for a contactor coil of this size — fast enough for motor starting, not fast enough for arc suppression in DC switching applications. Coil resistance is 0.638 Ohm inrush and 146.6 Ohm holding at 68 °F (20 °C). The inrush-to-holding ratio tells you the coil draws a high surge current to pull in, then drops to a much lower holding current — standard for economized DC coils. No built-in suppressor module, so you'll need to add a free-wheeling diode or varistor across the coil if driving from a PLC output or relay. Ambient air temperature for operation is 23...131 °F (-5...55 °C).
This coil is a service part for TeSys F contactors — the magnetic coil assembly that pulls the contactor in. It's used in motor control centers, panel builds, and replacement/repair of existing TeSys F contactors where the original coil has failed or the control voltage needs changing.
