Copeland 971-0090-36 1/4 HP-1/2 HP Overload Relay

The Copeland 971-0090-36 Overload Relay is an essential safety device for HVAC systems. It protects compressors having power capacities that range between one-fourth and one-half horsepower. This overload relay can be used for a wide range of applications because it operates at between 115 and 230 volts. This is because its primary function is to monitor the power supply coming into the compressor unit. Therefore, if there happens to be an electrical overload or high temperature situation, the circuit needs to be disconnected for compressor protection purposes. In turn this automatic protective mechanism diminishes overheating and electrical faults so as to enhance HVAC systems’ reliability and efficiency enhancement purposes . Under normal operating conditions, the relay reverts back by itself.
