The Schneider Electric TeSys LX4FG070 is a replacement contactor coil for the FG series of contactors, designed to operate on a 70 V DC control circuit. It's a DC wide-range coil without a built-in suppressor module, meaning you'll need to add external flyback diode or RC snubber protection across the coil terminals to protect the control circuit from voltage spikes during de-energization. The coil pulls in with an inrush resistance of 6.31 ohms at 20 °C, then holds on a 1402 ohm winding at the same temperature — that's a standard economized coil design that cuts holding power once the contactor is sealed. Operating time is 30 to 40 ms for closing and 30 to 50 ms for opening, which is typical for a contactor of this frame size.
The 70 V DC control voltage is the nominal; the coil will operate reliably between 0.85 and 1.1 times that (roughly 59.5 to 77 V DC) at 55 °C, and it drops out between 0.15 and 0.2 Uc (10.5 to 14 V DC) at the same temperature. That drop-out margin is important for applications where the DC bus might sag during a fault — the contactor will stay sealed until the voltage falls well below the nominal level. Rated for ambient operation from -5 to 55 °C, so it's fine inside a standard ventilated enclosure but not for direct outdoor exposure or freezer environments.
