The LX4FJ055 is a replacement contactor coil from the TeSys range, designed for FJ-frame contactors. It operates on a 55 V DC control circuit and uses low-consumption DC coil technology without a built-in suppressor module. Opening time is 45 to 60 ms; closing time is 50 to 60 ms. The coil draws a 3.16 Ω inrush resistance at 68 °F (20 °C) and 813 Ω holding resistance at the same temperature. Control voltage limits are specified: dropout occurs at 0.2 to 0.35 Uc at 131 °F (55 °C); operational range is 0.85 to 1.1 Uc at the same temperature. Ambient air temperature for operation is 23 to 131 °F (-5 to 55 °C).
