ICM Controls ICM493-60A 1PH Line Voltage Monitor W/Surge

The ICM Controls ICM493-60A Single Phase Monitor With Surge protects your single-phase HVAC equipment, such as mini-splits and inverter compressors. This continuously monitors the incoming voltage, acting as a sentinel. Your equipment is protected from damage by the built-in contactor, which quickly disconnects it if it senses voltage fluctuations outside of the acceptable operating range. Surge arresters offer further defense against harmful power surges brought on by lightning strikes and other electrical incidents. Not only does this preserve your pricey equipment, but it also prevents costly repairs and replacements.  In addition, the ICM493-60A has an easy-to-use backlit digital display that provides useful information about the voltage in your system as well as the current voltage.
