The LX1FH2772 is a replacement coil for the LC1F265 and LC1F330 contactors in the TeSys F line. When energized at 277 V AC, it draws approximately 10 W of power and dissipates 8 W of heat at 40...400 Hz, with a coil resistance of 113 ohm. The coil operates with a 100 ms response time and supports a maximum operating rate of 2400 cycles per hour at 55 °C. The coil is supplied without a built-in suppressor module. An external RC snubber or varistor should be added across the coil terminals when driving from a PLC output or solid-state relay.
Applications
TeSys F contactor coils like the LX1FH2772 are used in motor control centers, pump panels, conveyor systems, and HVAC equipment where the LC1F265 or LC1F330 contactor switches three-phase motors or resistive loads. The coil is the replaceable wear component that determines the contactor's pick-up voltage and operating cycle life.
