Components used to make the 3-phase contactor circuit 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. 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. ON/OF Delay Load

ON/OF Delay Load
Fig 4: ON/OF Delay Load
ON/OF Delay Load is a specialized type of clock used for measuring specific time intervals.An electromechanical cam ON/OF Delay Load uses a small synchronous AC motor turning a cam against a comb of switch contacts. This type of ON/OF Delay Load 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 ON/OF Delay Load have two main groups hardware and software ON/OF Delay Load.Most timers give an indication that the time interval that had been set has expired.

04. Fuse

Fig 5: Fuse
Fuses have Been Used as Essential Safety Devices From the Early Days of Electrical Engineering. Today There are Thousands of Different fuse Designs Which have Current Voltage ratings, Breaking Capacity, and Response Times, Depending on the Application. Electricity Component Current Operating Characteristics of Fuses are Chosen to Provide Adequate Protection Without Needless Interruption. House Wiring regulations usually define a Maximum fuse Current rating for Particular Circuits. When a Damaged live Wire Makes contact with a Metal Case that is connected to the Ground. A Short Circuit will Form and The Fuse will Melt.
