Trane MON0046 Phase Monitor 30A 115V 3-PH

The Trane MON0046 3-phase monitor protects HVAC equipment by checking voltage and current input in three-phase power applications. It shields expensive equipment, such as furnace and air conditioner components, from electrical damage and ensures top efficiency by shutting off the equipment whenever it notices phase malfunction, voltage that is either above or below the limits, or power interruptions. This small device measures 4.8’ ‘high and 6.0’ ‘wide. It is often used in commercial complexes and industrial complexes with a three-phase electrical supply.
