Contactor Interlock  Motor connection:

This diagram shows how to make Contactor Interlocking Wiring. This article is about contact interlock. Here, you will know how to operate the contact interlock. This article also includes a contact interlock circuit and connection diagram with the motor. Contact combination systems find applications in motor starters (star-delta), power control circuits, power switch circuits, etc. When an electrical circuit has two magnetic contactors, and there only one magnetic contactor needs to be turned on, at the same time then there need the interlocking system is used for this circuit.

Components used to make the Contactor Interlock  Motor connection:

01. Single-Phase Motor

Single Phase Motor
Fig2: 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.

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. DP MCB

Fig 4: 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.

04. Push Switch

Push Switch
Fig 5: Push Switch
A Push-Button is a Simple Switch Mechanism To Control Some Aspects of a Machine a Process. Buttons Are Typically Made Out of Hard Material, Usually Plastic or Metal. The Surface is Usually Flat or Shaped to Accommodate The Human Finger or Hand, so as to be easily Depressed or Pushed. Buttons are Most Often Biased Switches, Although Many unbiased Buttons still Require a Spring to Return to their Unpushed state. The "Push-Button" Has Been Utilized in Calculators, Various Other Mechanical and Electronic Devices, Various Other Mechanical and Electronic Devices, Kitchen Appliances, Push-button telephones, Home, And Commercial.

Frequently Asked Questions

What is a contactor interlock?

General: Type S contactors or starters could be mechanically interlocked so that only one device is energized at a time. The mechanical interlock is an interference (non-jamming) type, locking at the beginning of the stroke of any starter and contactor.

What is interlock wiring?

Electrical interlock on wire mesh. An interlock device was designed to allow a generator to provide a backup power supply in such a way that it (a) prevents the main and generator power supply from being connected at the same time, and (b) allows circuit diagram breakers to operate normally without interference in the event of the overload condition.

What is the main function of a contactor?

A contactor was an electrically controlled switch used for switching an electrical power circuit diagram. A contactor is typically controlled by a circuit diagram that has a much lower power supply level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-v motor switch.

What are the three main types of interlocks?

Interlocks and interlock systems could be classified into three main groups, based on the type of interconnection between the interlocks. These three groups or types were mechanical, electrical, and key interlocks. Each of these types has its advantages when properly designed or applied.

What is a hardwired interlock?

Hardwired safety interlocks are physical devices or circuit diagrams that are connected directly to the PLC inputs and outputs. They bypass the PLC logic and act independently of the software program. Examples of hardwired safety interlocks were emergency stop buttons, limit switches, pressure sensors, relays, or contactors
