Description
The ICM Controls Sentry 3N1 combines the benefits of an ICM517A-LITE single-phase surge protection device and an ICM492D single-phase voltage monitor into one easy-to-install solution, while also providing a convenient onboard disconnect breaker for safely switching power on and off. The Sentry 3N1 protects against both power surges and over/under voltage conditions that can damage circuit boards and motors in residential and commercial single-phase 208/240VAC HVAC/R equipment. All components are pre-wired for 208/240 volts in a modular design with field-replaceable parts. The field-programmable voltage monitor features an improved backlit digital display with 5-fault memory, protecting against over/under voltage and rapid short cycling caused by transient faults and power interruptions. A separate 40-amp contactor fully disconnects the unit from the service, and the 40-amp internal breaker allows for easy switching of power on and off. TMOV surge protection technology is built to withstand major surge events, with a diagnostic green LED indicating active surge suppression. Housed in a NEMA Type 4X rated, ultrasonically welded enclosure, the Sentry 3N1 is UL Listed and designed and manufactured in the USA. Backed by a limited lifetime product warranty with up to a 3-year, $25,000 connected equipment warranty. Compatible as a replacement for RectorSeal RSH-50VRM Kit-DC applications.
