SENTRY 3N1 ICM Controls - Field programmable single phase line voltage monitor

The Sentry 3N1 combines the benefits of a ICM517A single phase surge protective device, and an ICM492 single phase voltage monitor while incorporating a disconnect breaker into one easy to install solution. It provides techs and homeowners a convenient way to break the power, protect against power surges and over/under voltage issues that can cause damage to circuit boards and motors in residential and commercial single phase 240 VAC HVAC/R equipment.
