Description
The Copeland 940-C411-79 Current Relay is a high-performance electrical component designed for use in HVAC systems. The construction of the relay enables it to handle 30 amperes at maximum and work with 277 volts. Besides, you can use it to run high current circuits, due to its normally open contact structure. Thus, when electricity passes through the wires, the system opens or closes its contacts depending on the flow of this electrical current. At a set amount of electric current flowing through it, this particular relay becomes active or inactive; therefore serving as a controller over power supply to different components making up air conditioning units.
