Modular Contactor With Motor Wiring

Modular Contactor with Motor wiring:

This diagram shows how to make a Modular Contactor With Motor Wiring. In this circuit, we use a DP MCB ( Double Pole Minature Circuit Breaker ), an RCCB ( Residual Current Circuit Breaker ), a modular contactor, and a timer, a single-phase motor. First, we need to connect the DP MCB with a power source, then connect RCCB with DP MCB, then connect the modular contactor, then connect the timer and motor.

Components used to make the Project_name:

01. DP MCB

Fig 2: 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.

02. RCCB  

Fig 3: RCCB

The RCCB (Residual Current Circuit Breaker) or RCCB is an electrical protective device. A residual Current Circuit Breaker is specially designed to protect the electrical circuit against earth faults and humans from electrical shock. In this, under normal conditions the load is always connected between the phase terminal to the neutral terminal, hence the flow of the phase current is equal to the neutral current. Earth fault or fault in a power system can cause excess heating, more power consumption, burning or fire, etc. So, protection against earth leakage is very important.

03. Contactor 

Fig 4: 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)

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. Single Phase Motor

Single Phase Motor
Fig 6: 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.
