The LX4FH027 is a replacement contactor coil from the Schneider Electric TeSys F range, designed to drive the main contactor armature in the LX4FH series. It operates on a 24...30 V DC control circuit and pulls in between 40 and 50 ms, with dropout taking 40 to 65 ms. Coil technology is a DC low-consumption type without a built-in suppressor module — if your application requires flyback suppression (common with PLC or 24 VDC control systems), you'll need to add an external diode or RC snubber across the coil terminals.
Rated for 24...30 V DC control voltage, with operational limits of 0.85...1.1 Uc at 131 °F (55 °C). Drop-out occurs between 0.15 and 0.2 Uc. Inrush power draw is 750 W at 68 °F (20 °C) during pickup, dropping to 5 W holding power. The inrush resistance is 0.9 Ohm, holding resistance 192 Ohm — the inductance of the closed circuit is 26.3 H. These numbers matter for sizing your DC supply and verifying the drive capability of your control output.
This coil mounts directly into the TeSys F contactor frame — it's the service part that replaces a failed coil without swapping the entire contactor. Ambient operating temperature range is -5...55 °C (23...131 °F). Single-unit packaging. The category field lists this as 'World Service Parts (CTR Access)' — it's the authorized replacement part path for maintaining existing TeSys F installations rather than a new-design component.
