Overview
The LX4FF060 is a Schneider TeSys F contactor coil, order code LX4FF060, rated for 72 V DC wide-range control circuits with a power rating of 560 W and a consumption of 4.5 W.
This coil converts electrical energy into magnetic force to actuate the contactor armature. The 72 V DC wide-range control circuit accepts a broad DC voltage band, simplifying integration in systems with fluctuating DC supplies. The 4.5 W power consumption keeps thermal load low inside the panel, reducing derating concerns in enclosed cabinets. The coil lacks a built-in suppressor module, so an external diode or RC snubber (such as the LA4FDE suppressor module) must be added across the coil terminals to suppress inductive kickback when de-energizing. The 30 ms operating time and 60 cycles/hour maximum operating rate at 70 °C define the switching duty cycle for continuous applications.
Applications
TeSys F contactor coils like the LX4FF060 are used in motor control centers, conveyor systems, pump stations, and HVAC equipment where large contactors (LC1F115/LC1F150) switch three-phase motors or resistive loads. The coil sits in the control circuit, typically fed from a 72 V DC control transformer or battery-backed DC bus.
