It operates on 180 V DC control voltage and is a DC low-consumption type, meaning it draws a higher inrush current to pull in, then drops to a low holding current — 29.9 Ω inrush vs 7669 Ω holding at 20 °C. This is the coil only, not the full contactor; you swap it into an existing FJ contactor base. The 180 V DC control circuit voltage is the nominal coil rating — the part pulls in reliably between 0.85 and 1.1 Uc (153–198 V DC at 55 °C) and drops out between 0.2 and 0.35 Uc (36–63 V DC at 55 °C). If your control voltage sits outside that band, the coil won't hold or won't drop cleanly. Operating time runs 45–60 ms opening, 50–60 ms closing — typical for a DC coil of this size, but worth checking if your safety circuit timing budget is tight. The coil ships without a built-in suppressor module. That means you need to add an external flyback diode or RC snubber across the coil terminals if your PLC output or relay driving it can't handle the inductive kickback. On a DC coil this size, the back-EMF spike can weld relay contacts or kill a transistor output without suppression. ## Deployment context The 180 V DC control voltage is common in battery-backed or DC-distributed control systems — think UPS-fed panels in process plants or DC bus architectures.","metaTitle":"Schneider LX4FJ180 TeSys Contactor Coil, 180 V DC, Obsolete","metaDescription":"Schneider Electric TeSys LX4FJ180 contactor coil, 180 V DC, DC low consumption.
