Description
The Rheem-Ruud 42-25105-02 395V Start Relay is a essentialpart for air conditioners and heat pumps. This relay is made of thermal plastic polypropylene and is strong and durable, therefore ensuring that the compressor of your HVAC system starts up effectively. During the start-up process the compressor motor requires a certain amount of force to overcome the initial resistance. In this variant, the start relay offers a transient voltage of almost 395V. After the compressor has attained working speed the relay drops off and the compressor continues to run on the normal operating voltage. Why is a start relay supposed to work properly? It safeguards the compressor from electrical overload at the time of starting and it also helps the system to perform well by enabling it to start smoothly.
