It's the latching and unlatching coil set for TeSys F contactors — the 35...40 ms latching time and 50...100 ms unlatching time tell you the mechanical response you can expect when the control signal hits the coil. The 127 V DC control voltage is the nominal operating level — the coil holds reliably within 0.85...1.1 Uc (about 108 V to 140 V DC) for both latching and unlatching. Below that dropout range, the contactor may chatter or fail to pick. The average resistance figures — 32.75 Ω for the latching coil and 732.64 Ω for the unlatching coil at 20 °C — let you calculate inrush and holding current for your DC supply sizing. Rated for 1 Mcycles mechanical durability and 120 cycles per hour at 40 °C, this coil is built for moderate-duty cycling applications — think conveyor sections or pump starters that cycle a few times per minute, not high-speed press applications.","metaTitle":"TeSys LX0FG057 contactor coil, 127 V DC low consumption","metaDescription":"TeSys F LX0FG057 contactor coil, 127 V DC low consumption.

For a drop-in replacement, you would need to check the TeSys F contactor frame size and match a currently-produced coil with the same 127 V DC low-consumption rating and mechanical interface. Contact us with your contactor base part number and we can help identify a compatible current-production coil."},{"question":"What are the key electrical ratings for LX0FG057?","answer":"127 V DC control voltage with a tolerance range of 0.85...1.1 Uc. Latching coil resistance is 32.75 Ω at 20 °C; unlatching coil resistance is 732.64 Ω at 20 °C.
