Copeland 971-0329-15 Overload Relay

The Copeland 971-0329-15 Overload Relay acts as a guard for HVAC motors and compressors against excessive electrical currents and catastrophic injuries. This little relay is also efficient with dimensions of 3.6" by 2.7" by 2" and it runs on 420 VAC power supply. It primarily serves as a current monitor for the HVAC compressor or motor. In case these flowing currents exceed the recommended limits, this relay automatically breaks the circuit to avoid overheating or other mechanical failures. Thus automatic protection plays part in ensuring the operational integrity of this HVAC system.The overload condition can be eliminated automatically without any assistant from human beings, this is made possible by this relay.
