Automatic Power Changeover for 3 phases:
This diagram shows how to make a connection Automatic Power Changeover for 3 phases. In this circuit diagram, we use two DP MCBs ( Double Pole Miniature Circuit Breakers ), two timers, a relay, two magnetic contactors, and a power generator. First, we connect input power in DP MCB and then from DP MCB to connect the magnetic contactor and then from the contactor to connect the timer relay like our diagram. If you want to know more about this circuit diagram please check our youtube video below the link.

Components used to make the Automatic Power Changeover for 3 phases:
DP MCB In Two Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls two Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control two Different Electrical Circuits at the same time, which allows the Appliances to Isolate in a safe and reliable manner. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches.
02. 8-Pin Timer:
A timer is a type of time switching device that controls and controls electrical circuits and electrical and electronics devices through time setting (on/off). Timer is basically 8 pin. Like other controlling devices the timer has a coil and when this coil is magnetized, the timer works on/off. The timer has two common ends and each common end has normally close and normally open options. When the timer is set by time, the timer trips at the end of that time and turns the common’s normally closed (on) to open (off) and normally open (off) to close (on). This is how the timer works.
A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.
