Copeland 971-0090-47 Overload Relay The Copeland 971-0090-47 Overload Relay is a crucial component in protecting compressors from damage caused by overloads or short circuits. Its primary function is to monitor the electrical current flowing through the compressor and interrupt the circuit if the current exceeds a predetermined safe limit. This action safeguards the compressor from overheating, electrical faults, and other potential hazards. The relay operates on a bimetallic principle, where two dissimilar metals with different expansion rates are bonded together. When an overload occurs, the increased current flow generates heat, causing the bimetallic strip to bend and break the circuit. This interruption prevents excessive current from reaching the compressor, mitigating the risk of damage. The Copeland 971-0090-47 Overload Relay is designed for use with specific Copeland compressors. Its compact size and easy installation make it a convenient and reliable solution for compressor protection. It ensures the safe and efficient operation of compressors, reducing downtime and maintenance costs.
