The LX4FG300: The 300 V DC coil is a wide-range DC control type. It picks up reliably between 0.85 and 1.1 times Uc (255 to 330 V DC at 55 °C) and drops out between 0.15 and 0.2 Uc (45 to 60 V DC). That drop-out margin matters if you're running a long DC control loop with voltage drop — it won't nuisance-drop on a sagging line. Operating time is 30 to 40 ms closing, 30 to 50 ms opening. That's typical for a contactor coil this size — fast enough for motor starting, not so fast it hammers the contacts. The coil has no built-in suppressor module, so you'll need to add a free-wheeling diode or RC snubber across the coil terminals if your PLC output card doesn't handle the inductive kick. Coil resistance is 117.4 ohms inrush and 25,222 ohms holding at 20 °C. That high holding resistance means low steady-state power draw once the contactor seals — the coil economizer circuit inside the FG contactor does the work.

Frequently asked questions
What is the closest pin-compatible alternative to LX4FG300?
There is no official pin-compatible alternative listed for this coil. The LX4FG300 is the specific 300 V DC coil for TeSys FG contactors; other voltages in the LX4FG family (e.g., 220 V DC, 250 V DC) share the same mechanical footprint but differ in control voltage. Stick with the 300 V DC variant unless you're rewiring the control circuit.
What is LX4FG300's listed range?
It belongs to the Schneider TeSys range, which is the standard IEC contactor and motor starter family for industrial control panels.
What is LX4FG300's listed category?
It's classified under 18401-WORLD SERVICE PARTS (CTR ACCESS), meaning it's a service-part coil — not a full contactor assembly, just the replaceable coil.
What compliance documentation does Schneider provide for LX4FG300?
The evidence does not list specific compliance documents (RoHS, REACH, UL, IEC) for this order code. As a TeSys service part, it typically carries CE and UL markings, but confirm with the RFQ if a formal declaration is needed for your project file.
