How to make Star Delta Starter Wiring:

This diagram shows how to connect Star Delta Starter Wiring When connected to star, the speed of the motor increases slowly. In this the rotor of the motor does not get too hot, there is no pressure on the rotor, there is no problem in the mechanical function, the lifetime of the motor increases. This is why basically star delta connection of a motor is done together. So you can wire your house or office like this diagram very easily. If you want to learn how to connect this circuit clearly you can follow our youtube video link below.

Components used to make the How to make Star Delta Starter Wiring:

01. TP MCB

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

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. Overload Relay

Overload Relay
Fig 4: 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.

04. Motor Terminal Box

Motor Terminal Box
Fig 5: Motor Terminal Box
A Terminal Block Consists of Modular Housing With An Insulated Body That Secures Two Or More Wires Together. Terminal Blocks—Also Referred to as terminal Connectors, Connection Terminals, or Screw Terminals—are Used in a Wide Array of Applications Where Electrical Systems Need to be Safely Connected. Electrical Terminals are a Class of Electrical Connectors That are Used to Transfer Electrical Current From a Power or Grounding Source to use. Terminals "Terminate" by Crimping or Soldering to Wire or Cable.
