nVent RAYCHEM 460 Pipe Tracing Controller

nVent RAYCHEM 460 Pipe Tracing Controller

The nVent RAYCHEM 460 is a c-UL-us Listed single-point heat tracing controller designed for pipe freeze protection, flow maintenance and heat loss replacement applications. It includes a 5" inch color touch screen display for intuitive set up and programming right out of the box. The 460 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 Thermistor 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.
