The nVent RAYCHEM AMC-1B line-sensing thermostat is designed to control heat-tracing systems in nonhazardous locations. The AMC-1B senses pipe or tank wall temperatures and can be used to control a single heat-tracing circuit or as a pilot control of a contactor switching mulitple heat-tracing circuits. It can also be used to indicate low-temperature or high-temperature alarm conditions.
