The LX4FH350 is a replacement contactor coil from the Schneider TeSys range, designed for FH-series contactors. It's a 350 V DC wide-range control circuit coil with no built-in suppressor module — you'll need to add external flyback suppression if the circuit doesn't already have it. Coil pull-in resistance measures 163.6 Ω at 20 °C, dropping to 35028 Ω in the holding state. That's a high-ratio economy coil — it pulls hard to close, then drops to a low-power hold. Operating time is 40 to 50 ms closing, 40 to 65 ms opening. Control voltage limits: operational range is 0.85 to 1.1 Uc at 55 °C (about 298 to 385 V DC). Drop-out threshold is 0.15 to 0.2 Uc at 55 °C (52.5 to 70 V DC). Ambient operating temperature is -5 to 55 °C.
Sourcing reality — obsolete part
Schneider lists the LX4FH350 as obsolete. There is no official direct replacement order code in the lifecycle record.
