Sentry 3N1
Single-Phase Voltage & Surge Protected Disconnect
The Sentry 3N1 combines the benefits of an ICM517A-LITE single-phase surge protection device, and a ICM492D single-phase voltage monitor into one easy to install solution. It also provides techs and homeowners a convenient way to break the power using an onboard disconnect breaker. The Sentry 3N1 protects against both power surges and over/under voltage issues that can cause damage to circuit boards and motors in residential and commercial single-phase 208/240 VAC HVAC/R equipment.- All Components pre-wired for 208/240 volts
