The LX0FL020 is a TeSys F contactor coil from Schneider Electric, part of the TeSys range. It provides the magnetic actuation for a TeSys F contactor, converting an electrical control signal into the mechanical force that closes or opens the main power contacts.
Control circuit and timing
Rated for a 208 V control circuit, this coil accepts both AC (50...400 Hz) and DC supply — meaning it can be wired into either a 208 VAC or 208 VDC control loop without needing a separate coil variant. The unlatching time of 50 to 100 ms and latching time of 40 to 80 ms define the switching speed of the contactor it drives; these are the intervals a panel builder factors into sequence timing for motor starts or emergency stops.
Durability and operating rate
Rated for 1 million mechanical cycles, so it holds up through high-frequency switching in production machinery. The maximum operating rate of 120 cycles per hour at 104 °F (40 °C) sets the thermal limit on how fast the coil can be re-energized — useful to check when designing a rapid-cycling load like a stamping press or a packaging line.
Coil resistance values
The coil's average resistance is 20.2 ohms in the latching state and 2961 ohms in the unlatching state, both measured at 68 °F (20 °C). These figures matter for calculating inrush current and holding current in the control circuit — a sourcing engineer uses them to size the control transformer or DC power supply feeding the coil.
