The LX0FH055 is a TeSys F contactor coil from the TeSys range, a 48 V DC low-consumption control circuit coil designed for use with TeSys F contactors.
Key electrical ratings
Control voltage is 48 V DC, with a latching and unlatching voltage tolerance of 0.85 to 1.1 Uc, meaning the coil reliably picks up and drops out across a 40.8 to 52.8 V DC window — important for verifying control supply regulation during commissioning. Operating time is 50 to 100 ms unlatching and 45 to 50 ms latching, which sets the contactor's response timing for coordination studies in motor starter circuits. Coil resistance is 5.19 Ω for the latching winding and 74.26 Ω for the unlatching winding at 68 °F (20 °C), values useful for verifying winding integrity during incoming inspection.
