An automatic changeover switch is a set of components connected in a simple control circuit to control two (2) sources of power supplying the same load at a time.
Automatic changeover switches are used in situations where you want a second source of power to come in after the main or utility supply has gone, the second source could be a Generator or solar
In case the second source of power is Generator, when the power shuts down the changeover starts the generator automatically and also connects the load to the generator. when the main power comes back the changeover switch changes the position from the generator contactor to the main contactor and takes the generator into cooldown and then shut off the engine.
An automatic changeover switch can be either three (3) phases or a single (1)
No matter the rating, size and phase control circuit remains the same.
The generator automatic changeover switch comprises two (2) parts
Namely
Main component part and generator component part
MAIN COMPONENT includes
Timer on-delay
Relay(DC or AC)
Phase failure (single or three phases depends on the power)
The contactor ( with mechanical interlock)
Control circuit breaker
GENERATOR COMPONENTS includes
Timer on-delay
Relay(DC or AC)
The contactor ( with mechanical interlock)
Control circuit breaker
