Lennox 10B17 Potential Relay

The Lennox 10B17 Potential Relay is an essentialpart of HVAC systems, which is used to control the start of the compressor in the air conditioning systems and heat pumps. This relay operates through the voltage level in the compressor motor’s start winding and isolating the start capacitor from the circuit when the motor attains a certain speed. This also allows for an effective starting of the motor and at the same time protecting the air compressor from electromagnetic overload. The Potential Relay enhances system reliability and performance by allowing a fast and clean start of the compressor thus minimizing motor strain.
