3 Phase Magnetic Contactor Connection. It reveals the parts of the circuit as simplified forms as well as the power as well as signal connections in between the tools. A wiring diagram is a simplified conventional pictorial representation of an electric circuit.
In 3 power systems we use some devices between induction motor and supply which are a cb circuit breaker mc magnetic contactor or motor starter o l overload relay and nc no push button switches for on off and reset. Contactors are used to provide this isolation. Contactors use 120 volt standard power to energize a magnetic coil which causes a set of internal contacts to close and provide higher power to the equipment.
