The LX1FG600 is a TeSys F contactor coil rated for 600 V AC 50 Hz control circuits, designed as a replacement coil for the TeSys F contactor range. The part is now classified as obsolete per the manufacturer's lifecycle record.
Key electrical characteristics
The coil draws 805 VA inrush at 50 Hz (cos phi 0.3) and holds at 55 VA, dissipating 18 to 24 W during continuous operation. These figures set the transformer sizing and thermal budget inside the panel. Control voltage limits are specified for 50/60 Hz at 131 °F (55 °C): drop-out occurs between 0.35 and 0.55 Uc, and the operational range is 0.85 to 1.1 Uc. This defines the hold-in margin for brownout conditions. Closing time is 20 to 35 ms, opening time 7 to 15 ms. The coil has no built-in suppressor module; an external RC snubber or varistor must be added across the coil terminals for inductive load switching.
Mechanical and thermal ratings
Ambient air temperature for operation spans 23 to 131 °F (-5 to 55 °C). Average coil resistance is 124.2 ohms at 68 °F (20 °C), with an inductance of 18.25 H in the closed circuit. These values are useful for verifying coil integrity with a multimeter during troubleshooting.
