The LX0FL057 is a replacement contactor coil from the Schneider Electric TeSys F range, designed for DC low-consumption control circuits at 127 V DC nominal. It controls the unlatching and latching of the contactor within 50...100 ms and 40...80 ms respectively, with a control voltage tolerance of 0.85...1.1 Uc for both functions. The coil draws a steady-state current defined by its resistance: 25.39 Ω latching and 452.27 Ω unlatching at 20 °C, which keeps heat dissipation low in a sealed panel.
Rated for 127 V DC control circuits, the coil operates within 0.85...1.1 Uc (roughly 108...140 V DC), so verify your control supply stays in that band — a sag below 108 V may fail to latch. Mechanical durability of 1 million cycles and a maximum operating rate of 120 cycles per hour at 40 °C suit moderate-duty cyclic applications like conveyor or pump control.
