Copeland 940-0090-04 Current Relay Kit

The Copeland 940-0090-04 Current Relay Kit acts as an essential part in the protection of compressors against various damages. It performs the safety function by basically measuring the electric current passing. Whenever that current reaches a level where it can cause damage-like about 27.2 amps for this kit, it shut down the motor and thus save the entire unit of HVAC from further damage. Operating and mounting this relay kit on a panel is quite easy. The 940-0090-04 has features that make it perfect for application with many Copeland compressors at 50 or 60 Hz electric supply. For one, it prevents costly motor damages to compressors caused by the high in-rush current consumptions. Secondly, it also lessens instances of compressor failure since technicians are able to diagnose them during the early stage. In this way, the relay kit enhances general performance and minimizes the chances of failure with costly repair of an HVAC system.
