Components used to make the 3-Phase Star & Motor:

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. Magnetic Contactor

Fig 3: Magnetic 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. 3-Phase Motor

Fig 4: 3-Phase Motor

The measuring device with the help of which the electric power or energy of a circuit is measured is called Energy Meter (Energy Meter). Also called a watt-hour or kilowatt-hour meter. For home appliances, we used a single-phase energy meter and for commercial or industrial applications we used a three-phase energy meter. For power above 10KW, we use three-phase energy meters. We also called these meters poly-phase meters. The three-segment meter additionally statistics consumption in kVAH and kVArH.

04. NO Switch

Fig 6: 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.

05. NC Switch

Fig 6: 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.

06. DP MCB

Fig 7: 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.

07. Overload Relay

Fig 8: Overload Relay

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.
