It's the replacement coil for TeSys F contactors that need a 127 V DC pull-in and hold circuit. The coil draws two distinct resistance paths: 30.98 Ω for the latching winding at 20 °C, and 458.45 Ω for the unlatching winding at 20 °C. This dual-winding design is what gives it the \"low consumption\" label — once latched, the hold current drops significantly. Operating time is 50...100 ms for unlatching and 45...50 ms for latching. That's fast enough for most motor-starting and switching applications, but not for high-speed counting or precision timing circuits. The 127 V DC control voltage is specific — not 110 V DC, not 125 V DC, not 24 V DC. If your panel's control transformer or DC supply is 127 V nominal, this coil matches. The control voltage limits are 0.85...1.1 Uc for both latching and unlatching, so it holds in from roughly 108 V to 140 V DC. That's a solid duty cycle for a contactor coil — good for frequent starting applications like conveyors or compressors, but not for continuous high-speed cycling.","metaTitle":"TeSys LX0FH057 Contactor Coil, 127 V DC Low Consumption","metaDescription":"Obsolete TeSys F contactor coil LX0FH057, 127 V DC low consumption, 50-100 ms unlatching.
