Description
The Johnson Controls R310AD-1 Current Sensing Relay is a modern tool for measuring and controlling the current in HVAC systems. This relay can work optimally at the temperature of -20°F to 150°F when it is working at 30V AC. The working of this current-sensing relay is based on the detection of the electrical current that is going to pumps, fans and compressors of an HVAC system. It comes on when the current rises above a specified value and allows timely correction of anticipated system overloads or defects.
