Schneider Electric (Square D) LUCA32FU Overload Relay & Control Unit

The Schneider Electric (Square D) LUCA32FU Overload Relay & Control Unit operates as an essential electrical protective part that monitors motor currents to protect HVAC equipment motors from overloads and phase loss situations. The unit operates through continuous current measurement of motors until the current exceeds a predetermined threshold for a designated time when it automatically cuts off power to protect the motor from damage. The Relay used HVAC system through air handlers and pumps and compressors primarily. The system extends motor operational time while minimizing equipment stoppages because of motor breakdowns and improving system dependability.
