0 Introduction And Working Principle of MCB And RCCB

What Is MCB?

MCB (miniature circuit breaker) is an electromagnetic device that embodies the entire enclosure in a molded insulating material. Main function of MCB is to open the circuit automatically when current passes through it exceeding the value for which MCB is set. MCB can be manually switched ‘On’ and ‘Off’ just like normal switches if necessary.
The device starts its operation for protection whenever overload occurs long enough to create danger to circuit. MCB does not respond to the transient loads like motor starting currents and switching surges. Usually, they are designed to work at less than 2.5 milliseconds during the short circuit fault and 2 seconds to 2 minutes when overload occurs.
Miniature circuit breakers are manufactured in varied pole versions like single, double, triple and four pole structures with distinct fault levels of current.

Working Principle Of MCB

The tripping operation of MCB is achieved with bimetallic strip when continuous over current passes through the device; bimetallic strip gets heated and deflects by bending. Deflection of the strip releases mechanical latch. The latch is attached with the operating mechanism, which allows MCB contacts to open. But during short circuit, sudden rise of current causes electromechanical displacement of plunger that is associated with solenoid of MCB or tripping coil. The plunger strikes trip lever resulting release of latch mechanism as a result circuit breaker contacts open.

Meaning Of RCCB (also called ELCB)

RCCB (residual current circuit breaker) is a type of circuit breaker, which is a current sensing electrical device utilized to protect low voltage circuit if fault occurs. The switch in it turns off whenever fault occurs in circuit.
The device is aimed at guarding individual from risks of electrocution, electrical shocks and fires, which are occurred because of earth or wiring faults. It is useful in the situations when there is sudden earth fault occurs in circuit. Example, an individual comes in contact with open live wire. In such kind of condition, if there is an absence of RCCB in circuit, the individual is at risk of receiving electrical shock.
However, in case the circuit is protected with RCCB, it will trip circuit immediately thus protecting the person from electric shock.

Working Principle of RCCB

Principle behind device operation, in ideal situations, current flows into the circuit via live wire should be similar as returning current from neutral. In case of earth fault, current finds passage to the earth through accidental mode (like accidental contact with open wire etc.). As a result, returning current from the neutral is reduced. Difference in current is too known as ‘Residual Current’.
RCCB is made in a way that it continuously compares for differences in the current values between neutral wires and live wires. Any small change in current value would trigger RCCB to trip off circuit.
According to studies, an individual is capable to sustain electric shock only to magnitude of 30mA. RCCBs are created in a way; they will trip off circuit even for a small change in residual current of up to 30mA. Response time is around 40 millisecond to make sure that the individual is completely protected from electric shocks.

2 Miniature Circuit Breaker (MCB) and Isolator – A Comparison

Electricity plays an important role in the society we live. Almost all the home appliances and the industrial machines work on electricity. Despite its usefulness, electricity can be quite harmful for us when any fault occurs in electrical system. Common faults like short circuit or power overload may result in costly equipment damage. Prevention of such unwanted situations is a must and for these, MCBs and Isolators are integrated in the electrical circuits these days.

Introduction of Miniature Circuit Breaker MCB

It is an automatic tripping switch that is designed by utilizing electromechanical techniques to avoid short circuit or power overload damage. MCB has a solenoid inside and is kept at specific voltage level to keep triggering mechanism in proper balance. Once a problem is assessed in circuit, switch is triggered and then flow of current is discontinued. After resolving the issue in circuit, the MCB can be manually switched on again.

About Isolator

Mostly found in commercial electric system, isolators disconnect circuit from main power supply. The electrical product is used when the system needs to be disconnected from main supply for performing maintenance that involves direct contact with current carrying parts of machinery.

Key Difference Between Miniature Circuit Breaker (MCB) and Isolator

  • MCB is an on-load electrical device that means the circuit breaker works with the energized line whenever a fault occurs. Isolator is purely an OFF-ON manual mains switch which has now been redesigned in miniature size to be compatible with MCB sized Distribution Boards.

If you want to buy best MCB or MCB Isolator online in India, it is advised to browse Protection Devices > MCB's & Protection Devices > Isolators. The site showcases a huge variety of electrical products at reasonable prices.

0 Solar (Net) Energy Meters At Home And Office

Solar energy metering or Net energy metering or net metering permits customers who generate their own solar electricity to monitor their energy consumption as well as production. When more electricity is produced than required, excess power is returned to grid through power meter by reversing meter from its normal direction. As a result of energy meter working in both the directions – one way to measure purchased power (when on-site need is more than on-site power production), the other way to measure returned power to grid – the consumer pays the ‘net amount’ of both the transactions.

Now, we are going to discuss about why we require such sort of metering:

Control Electricity Bills

Consumers are allowed to produce their own power efficiently by the net energy meters. At day time, most of the solar consumers generate more power than they use; net metering permits them to export that electricity to grid and reduce the electric bills.

Protect Electric Grid

The net metering policies make a smooth demand curve for the electricity and permit the utilities to manage peak electricity loads in a better way. By encouraging production near to point of consumption, net energy metering reduces strain on distribution system and restricts loss in long distance power distribution and transmission.

For purchasing Solar Net Energy Meters, go to www.bestofelectricals.com, a leading website where you can buy all types of meters and other electrical products of premium brands.

0 Meaning, Composition And Uses Of Armoured Cables

Armoured cable is a kind of cable that is covered in metal sheath. The cable is a bundle of wires, encased in metal tube or covering, which is further enclosed in plastic insulation layer. Metal covering saves wires from any type of wear and tear or physical impact. Such cables are little heavier in comparison of normal wires and quite hard to bend.

The Composition

  • At first, the conductor (normally a plain stranded copper) is chosen.
  • For the protection of conductor from water-damage, insulation is utilized. It too protects conductor from metal component i.e. armour.
  • Now bedding is done, which is actually PVC. It works like a barrier between inner component of conductor and outer parts.
  • After that, armour is placed over bedding for protecting the cable from any sort of stress. Sometimes, it is utilized as the ‘earth cable’.
  • Last part, cable sheathing is done to guard inner cable components. Also, it saves the cable against mechanical damage.

Uses Of Armoured Cables

Armoured cables are majorly used in commercial applications. Several states allow the utilization of such cables in residential applications as well. The cables are appropriate for underground cabling like in underground transport networks and sewers.

When the cables are utilized in public places, there should be a special kind of sheath on it i.e. LSZH (Low Smoke Zero Halogen). In case of fire, the sheath emits extremely low smoke and no toxic halogen thereby reducing calamities.

To buy armoured cables online, you are advised to give a visit to www.bestofelectricals.com. At the site, you can find the wires of brands like Polycab, KEI, Havells, etc. of varied sizes and distinct cores (ranging from 2 to 30).

0 Power Strips And Surge Protectors: What’s The Difference?

Most people think that power strip is the same electrical product as surge protector but the fact is, it is not true, even if they both look similar. Going through the below written content will give you a knowledge about the main difference between these two and will enable you to take the right decision.

The Power Strip

It is a block of electrical sockets, which attaches to the end of flexible cable, letting multiple electrical items to get power from single socket. We need power strips when several devices are in proximity like video, audio, appliances, computer system, lighting and power tools.

The capacity of the device differs from one type to another. Usually, the least number of outlets it has is two. And, some of the types can accommodate around twenty devices at once. Indeed, function of power strip is necessary; however, there is a certain limit of its performance.

Surge Protector

A surge protector is a device or appliance to protect the electrical products from voltage spikes. It tries to limit voltage supply to the device by shorting to ground or blocking any unwanted voltages above safe threshold.

Voltage spikes or increase can be caused by power outages, lightning strikes, short circuits, tripped circuit breakers, etc. The surge protector will detect when the voltage is about to increase and then divert extra voltage to ground wire. In this way, none of your electronic products will be harmed.

Price Gap

Due to more benefits provided by surge protector, it is little more expensive than power strip. Yet, it is not steeply priced and is a worthy deal, especially if you are residing in locations that are prone to power tripping, bolts of lightning and other electrical deterrents.

In all, if you are using UPS with some of your sensitive devices, reside in an area with no voltage spikes issue and you want to save your bucks then you can go for power strip as well. But if you do not find yourself in the aforementioned situation then it would definitely be logical to buy surge protector to ignore any unwanted expenditure on repairing of electrical products.

Checkout power strips, to find 3+1, 4+1, 4+4, 6+1, 8+1 of various brands like Anchor, Cona, GM, Philips and many more.
