A motor is started with the help of a potential relay that switches off the start capacitor in automotive AC systems. It assists in an efficient starting of the motor since the capacitor is disconnected as the motor attains a given speed thus avoiding destruction and enhancing dependability.

The Purpose of a Relay is to control multiple electrical components at once.
current relay are using for over current low state & high state.but potential relay are related to voltage.
The purpose of relay for life is to raise money for cancer and find a cure for it.
The voltage for a potential relay will depend on the circuit that the relay is installed in. The relay can be made for low voltages (5v) to higher voltages (440.)
Headlight relay.
A relay switches heavier power loadings than a regular switch.

Common wire of the potential relay goes to the compressor contactor. (5) Start wire of the potential relay goes to compressor run capacitor. (2) Run wire of the potential relay goes to the start capacitor. (1)
don't relay know
Potential or voltage relay is used for assisting the motor to start. Its operation is based on the increase in back-electro-motive force (back-EMF).
