The LX4FF022 is a replacement contactor coil from the Schneider Electric TeSys range, designed to fit FF-frame contactors. It operates on a 22 V DC control circuit, with a closing time of 30 to 40 ms and an opening time of 30 to 50 ms. The coil draws a 0.88 Ohm inrush resistance at 68 °F (20 °C) and holds at 159 Ohm at the same temperature.
The 22 V DC control voltage is a wide-range DC type. Operational limits are 0.85 to 1.1 times Uc at 131 °F (55 °C). Drop-out occurs between 0.15 and 0.2 Uc at 131 °F (55 °C).
This coil is a service part for TeSys FF contactors, which are DIN-rail or panel-mount devices common in motor control centers and distribution panels.
