nVent RAYCHEM 465 Fire Sprinkler Freeze Protection Controller

The nVent RAYCHEM 465 is a c-UL-us Listed single point heat tracing controller designed for fire sprinkler/fire suppression systems. It includes a 5" inch color touch screen display for intuitive set up and programming right out of the box. The 465 controller may be used with line-sensing or ambient-sensing and Proportional Ambient-Sensing Control (PASC) modes. It measures temperatures with two 2 KOhm / 77°F (25°C), 2-wire Thermistors connected directly to the unit. The controller can also measure ground fault current to ensure system integrity. The controller includes ground fault current sensing and relaying equipment compliant with UL1053 standard.
