Timer Contactor diagram:
This diagram shows how to make a timer contactor wiring diagram. In this circuit, we use 3 TP MCBs( Tripple Pole Minature Circuit Breaker ), three magnetic contactors with overload, and three 3-phase motors. First, we need to connect MCB with a power source, then connect all components with a circuit like our image. Now this circuit is ready to use.

Components used to make the Timer contactor wiring:
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. ContactorÂ

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. TimerÂ

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.
04. OverloadÂ

| Fig 5: Overload |
Overload relays are often used to protect the motor from excessive current flow. Overload relays are used to protect the motor from overheating. Besides some specific faults such as phase to phase, phase to ground, etc. overload relay provides protection to the motor. A thermal overload relay works on the principle of bimetallic strip electro-thermal characteristics. When the bimetallic heats up, the trip function in the overload relay turns on and disconnects the power supply to the contactor coil, thus tripping the overload relay and breaking the motor current and saving the motor.
05. 3 Phase Motor

A Three-Phase Motor is an Electric Motor That Typically Receives its Power From a Three-Phase System (three-phase current) This can be realized via a Three-Phase Mains Supply or a Frequency Inverter. Three-Phase Motors are Available as Synchronous and Asynchronous Motors. Three Phase Alternating Current Power Motor is Economical to Supply Power to the data Center Since it Requires Less Conductor Material to Supply Electricity. This Explains Why 3 Phase Alternating Current Motor is Used in Electric Transmission, Generation, and Distribution in Most Countries Worldwide.
