Timer and Contactor wiring diagram:

This diagram shows how to make Timer and Contactor wiring. In this circuit, we use an SP MCB ( Single Pole Circuit Breaker ), a magnetic contactor, a timer, and a lamp. First, we need to input Phase to SP MCB and input neutral to the magnetic contactor. Then from SP MCB connect the phase line to the contactor at all points like our diagram. Then from the magnetic contactor connect input power to the timer and lamp. Then this circuit is ready for use.

Components used to make the Timer and Contactor wiring:

01. Magnetic Contactor:

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.

02. SP MCB:

In single-pole MCB, Switching & Protection is Affected in only one Phase. Single phase supply to break the phase only. A single Pole breaker is Typically used with 120-volt Circuits, 15-20 amps. They are constructed with one Hot Wire and one Neutral wire. An SP switch is the most basic General-Purpose switch that you use to Control a light or another device from one location. These Switches have two Brass-Colored screw Terminals Connected to the hot Power source wires. Pole refers to the number of Circuits Controlled by the Switch SP Switches Control only one Electrical Circuit.

03. Timer:

A timer is a type of time-switching device that controls and controls electrical circuits and electrical and electronic devices through time setting (on/off). The 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.

04. Light:

CFL stands for Compact Fluorescent Lamp which is an improved version of tube lights of earlier days. Like tube lights, it is a vacuum glass tube with fluorescent powder coating which is not as long and straight as tube lights but curved/twisted compact, or small in size. Like a tube light, it has electrodes or filaments at both ends. But in this case, instead of a choke, there is an electronic circuit that drives the Compact Fluorescent Lamp. Because the red wave is less in the light of the Tubelight and Compact Fluorescent Lamp, the object looks a little pale or the correct color of the object does not appear.
