Rated for a 250 V DC control circuit, it pulls in at 750 W inrush and holds at 5 W, with an average inrush resistance of 84 Ohm and a holding resistance of 13900 Ohm at 68 °F (20 °C). Closing time runs 40 to 50 ms; opening time is 40 to 65 ms. The 250 V DC coil is the key fit parameter — it is not a universal AC/DC coil. If your panel runs a 250 V DC control bus, this coil matches directly. The 0.85 to 1.1 Uc operational voltage range (212.5 to 275 V DC at 131 °F) gives some margin on a nominal 250 V bus, but the drop-out band of 0.15 to 0.2 Uc (37.5 to 50 V DC) means the contactor drops out cleanly on a low-voltage condition. The coil has no built-in suppressor module, so you will need an external flyback diode or RC snubber across the coil terminals to protect your DC control circuit from inductive kickback. Mounts onto the TeSys F contactor base. The DC low-consumption design keeps thermal rise in the panel lower than an AC coil running through a rectifier — relevant if the contactor is in a sealed enclosure with limited airflow. Inductance of the closed circuit is 1910 H, which governs the inrush current profile and the sizing of any external suppression circuit.","metaTitle":"TeSys LX4FH250 contactor coil, 250 V DC, obsolete","metaDescription":"Obsolete TeSys F contactor coil LX4FH250, 250 V DC control circuit. 40-50 ms closing, 10 Mcycles mechanical durability.
