The LX0FG020 is a TeSys F contactor coil from Schneider Electric, designed to energize the magnetic circuit of TeSys F contactors. It operates on a 208 V control circuit, accepting either AC (50...400 Hz) or DC supply, which simplifies panel wiring when both supply types are available. The coil's latching time is 35...40 ms and unlatching takes 50...100 ms, meaning the contactor pulls in quickly but releases with a slight intentional delay to avoid chatter from brief supply dips. The control voltage must stay within 0.85...1.1 Uc for reliable operation — at 208 V nominal, that's 176.8...228.8 V.
Duty cycle and mechanical life
Rated for 1 million mechanical cycles and a maximum operating rate of 120 cycles per hour at 104 °F (40 °C), this coil suits applications with moderate switching frequency — conveyor sections, pump start/stop, or fan cycling. The average coil resistance is 21.3 Ω for the latching winding and 3169 Ω for the unlatching winding at 68 °F (20 °C), which lets you calculate inrush and holding current for your control transformer sizing.
