Single Phase Motor Starter with Timer:
This diagram shows how to make a single-phase motor starter with a timer. In this circuit, we use a DP MCB ( Double Pole Miniature Circuit Breaker ), an ELCB ( Earth Leakage Circuit Breaker ), a magnetic contactor, a single-phase motor, and a timer. First, we need to input power to DP MCB, then from DP MCB to input power ELCB, then input power to contactor and timer from ELCB. And lastly input power to the motor. Now this circuit is ready for use. If you want to know more about this circuit please check our youtube video below the link.

Components used to make the Single Phase Motor Starter with Timer:
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.
ELCB complete earth leakage circuit breaker works on earth leakage production. Usually, the ELCB circuit breaker has two cables Phase and Neutral if any load is directly connected to the earth without taking neutral from ELCB then the circuit breaker will trip automatically. Earth leakage circuit breakers are used in applications to prevent electric shock and electrical fire caused by a short circuit or overload in the control panel by automatically closing when leakage is detected.
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.
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 Single-Phase Motor is an Electrically-Powered Rotary Machine That Can Turn Electric Energy into Mechanical Energy. It Works by Using a Single-Phase Power Supply. Single-phase Motors Are Used in Equipment And Machines That Are Smaller in Size And Require Lower Horsepower. This Includes Equipment Such As Refrigerators, Pumps, Compressors, Fans, and Portable Drills. Single-Phase Motors Have a Similar Construction to The Three-Phase Motor, Including an AC Winding That is Placed on The Stator And Short-Circuited Conductors That are Placed in a Cylindrical Rotor.
