The LX1FG056 is a replacement contactor coil from the Schneider Electric TeSys F range, designed to be mounted onto the corresponding TeSys F contactor base. It operates on a 56 V AC 50 Hz control circuit and is supplied without a built-in suppressor module, so the installer must add external suppression (RC snubber or varistor) across the coil terminals to protect the control circuit from voltage spikes during de-energization. The coil draws an inrush power of 805 VA at 50 Hz (cos φ 0.3) and settles to a hold-in power of 55 VA at 50 Hz (cos φ 0.3), with a steady-state heat dissipation of 18 to 24 W at 50 Hz. The closing time is 20 to 35 ms and the opening time is 7 to 15 ms, which is typical for a contactor of this frame size and governs the timing coordination in a motor-starting circuit.
If you need a drop-in replacement, the practical approach is to verify the mechanical fit and electrical ratings of the complete TeSys F contactor assembly (contactor base plus coil) as a unit, rather than sourcing the coil alone. The coil's control voltage (56 V AC 50 Hz) is an uncommon value, so a contactor replacement with a different coil voltage may require a control-circuit transformer change.
Key electrical characteristics for fit verification
The coil's control circuit voltage limits are specified at 131 °F (55 °C): dropout occurs at 0.35 to 0.55 Uc (19.6 to 30.8 V AC), and the operational range is 0.85 to 1.1 Uc (47.6 to 61.6 V AC). This means the coil will reliably pick up and seal in when the control voltage is within 47.6 to 61.6 V AC, and will drop out when the voltage falls below approximately 20 to 31 V AC. The ambient air temperature range for operation is 23 to 131 °F (-5 to 55 °C). The coil has an average resistance of 1.04 Ω at 68 °F (20 °C) and an inductance of 0.17 H when the contactor is closed. These figures define the coil's suitability for high-duty-cycle applications like conveyor systems or pump cycling.
