Why Use a 3-Phase Motor Protector?

Three-phase motors are the workhorses of commercial HVAC systems — powering compressors, chillers, air handlers, and more. Without proper protection, phase loss or imbalance can cause motors to draw excessive current, overheat, and fail prematurely. The Supco TPMPU acts as a vigilant electronic guardian, continuously monitoring incoming power quality and disconnecting the motor load when unsafe conditions are detected.

Ideal Applications

• Commercial HVAC compressors and condensing units
• Chiller and cooling tower motors
• Air handler and blower motors
• Pump and fan motors in mechanical rooms
• Refrigeration equipment motors
