Timer Wiring:

This diagram shows how to make an electrical timer wiring diagram. In this circuit, we use a TP MCB ( Tripple Pole Minature Circuit Braker ), a magnetic contactor, and a timer. First, we need to connect TP MCB with Power Source, then connect the magnetic contactor with MCB, then connect the timer relay with the MCB. Now this circuit is ready to use.

Components used to make the Timer diagram:

01. TP MCB

Fig 2: TP MCB

Three wires can be controlled by a triple pole MCB. Triple pole MCB circuit breakers are generally used in three-phase lines. A triple-pole MCB circuit breaker has three wires at its input and three wires at its output. But one can use this circuit breaker in a single-phase line. TP MCB widely used in industries. The reason is that it has three poles. And this TP circuit breaker is used to provide three-phase and three-phase connections. A neutral is not normally used in three-phase lines. But a 4-pole MCB circuit breaker is used if needed.

02. Contactor

Fig 3: Contactor

A magnetic contactor is an electrical device used for load control, automation, and protection. It is much like a magnetic reel. However, relays are generally used for low power and voltage, on the other hand, when we think of high power, these heavy-duty contractors only come to mind. It basically works by switching the load on and off. It has 3 terminals whose inputs are denoted as L1, L2, L3, and outputs as T1, T2, and T3. The circuit of the load is made in automation mode or protection using auxiliary contacts. It has two types of terminals. 1) Normally Open (NO). 2) Normally Closed (NC)

03. Timer

Fig 4: Timer

Timer is a specialized type of clock used for measuring specific time intervals.An electromechanical cam timer uses a small synchronous AC motor turning a cam against a comb of switch contacts. This type of timer often has a friction clutch between the gear train and the cam, the cam can be turned to reset the time.A simple example of the first type is an hourglass. Working method timers have two main groups: hardware and software timers.Most timers give an indication that the time interval that had been set has expired.
