star delta starter wiring diagram

Star-Delta starter diagram:

This diagram shows how to make a star delta starter wiring diagram. In this circuit, we use a TP MCB ( Tripple Pole Minature Circuit Breaker ), a magnetic contactor with overload, a timer, a DP MCB ( Double Pole Minature Circuit Breaker ), an NO Switch, an NC Switch, 3 SP MCBs ( Single Pole Minature Circuit Breaker ), and a 3 phase motor. Here we need to connect all components very perfectly for use.

Components used to make the 3-phase Motor 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. 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. Overload

Fig 4: 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.

04. Timer 

Fig 5: 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.

05. DP MCB

Fig 6: DP MCB

Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

06. NO Switch

Fig 7: NO Switch

The operator switch has its contact in Normally Open condition. To make Ladder Logic you need to understand NO contact. A Classic Switch has one Input And one Output. In "No Switch," YoungBoy Raps About Ammunition, Murder, Firearms, and Firearm Attachments Such as a Switch. The contact of the switch whose contact is already open is NO. That is enough to understand. no switch in a circuit, then the circuit will not function as intended. to write a program such that when the red light is on, This switch is now in normally open condition. When you push the switch it will close and the red light will turn on.

07. NC Switch

Fig 8: NC Switch

Indicates the contacts of switches or automatic actionable devices. Simply put, the push switches, magnetic contactors, and relays that we use in the factory Normally have Close Contact exists. At this moment the switch will be in normally closed condition. Because already he is sitting close. When turned off the contact will open. To make ladder logic you need to understand NC contact. As already explained. The switch contact is already closed in NC. That is enough to understand.

08. SP MCB

Fig 9: SP MCB

MCB SP means single pole it protects only one phase switching. MCB (Miniature Circuit Breaker) Curswitch 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. (MCB) For any Distribution Board, the Protection System Must be Used in The Incomer. Phase and Neutral Single Phase Supply to break. 120-volt circuits, 15-20 amp single pole breaker is typically used.

09. Single phase Motor

Fig 10: Single phase Motor

Single-Phase Induction Motor is Very Simple in Construction, Economical, Reliable, and Easy to Repair And Maintain. Due to all these advantages, it is widely used in vacuum cleaners, fans, centrifugal pumps, blowers, washing machines, etc. It can run only by supplying 1 phase current through this motor. The main two parts of this motor are Rotor and Stator. Among them, the rotating part is the Rotor and the stationary part is the Stator. Like all induction motors, a single-phase induction motor consists of two main parts, the stator, and the rotor.
