Copeland 940-0172-04 Current Relay Kit

The Copeland 940-0172-04 Current Relay Kit is an essential component of heating and cooling systems that improves efficiency and reliability. This 2.5" long solid-state operates at 120 V. The relay kit ensures protection and maximum efficiency by recognizing the current flow to the compressor. The current flowing through it is detected by the relay when it starts up and turns on the start capacitor which gives a improve to the compressor motor drive. When the motor attains the desired speed then that relay would disconnect the start capacitor therefore enabling an effective operation of the compressor using run capacitor. Among other benefits, this relay kit includes an increase in starting up speed for the compressor as well as improved overall system efficiency with prevention against possible electric faults.
