Overload Relay
An overload relay protects the compressor motor from damage due to excessive current draw. The relay monitors the current flowing through the motor and, if it exceeds a certain threshold, will trip and shut off power to the motor. This prevents the motor from overheating and potentially burning out.
In order for your HVAC system to operate safely and efficiently, it is imperative that the overload relay is sized and set correctly. If the relay is set too high, it may not trip when needed, allowing the motor to overheat. If it is set too low, it may trip unnecessarily, causing the system to shut down when it is not needed. With PartsHnC, you can find top brands and cost-effective overload relay prices.
