Circuit Breaker

The Earth Leakage Circuit Breaker, or what is known as the differential breaker, is one of the most important electrical protection elements that are used in household, commercial, industrial and other installations, because of its importance in protecting individuals from shocks and electric shocks that occur when they come into contact with the structures of electrical appliances.

What is a Circuit Breaker ?

The Circuit Breaker or what is known as the differential breaker is a breaker designed to protect people from leakage current and direct it to the ground, as the breaker is available with standard currents rated in the ampere unit, and it also has several sensitivity values ​​determined by the manufacturer.

Circuit breaker idea

• The idea of ​​his work depends on comparing the value of the current entering the circuit for one phase or the sum of the current entering the circuit for the three phase with the value of the current leaving it, which is Neutral current.
• In the event of a difference between the incoming and outgoing current with a value greater than the value of the cutter sensitivity current, this means that there is a current leakage outside the circuit, and this leads to the separation of the earth leakage circuit breaker for protection.
• In the normal case of the ground leakage circuit breaker, the sum of the currents (the directional sum) is equal to the value of the return current in the Neutral line, the flux arising inside the magnetic loop will be equal to zero, and therefore the current fed from the circuit breaker below the loop will remain connected.

Where to use the ground leakage breaker

The cutter is used in all electrical installations, such as:

• Residential buildings.
• offices.
• Shops.
• Industrial facilities and workshops.
• schools.
• Public buildings.

Earth leakage breaker test

The breaker is usually provided with a Test switch with the letter T written on it, and its function, when pressed, is to intentionally leak a small part of the current, and thus the breaker will disconnect the circuit from the inside.

Conditions for selecting a ground leakage circuit breaker

There are three important conditions to know before buying a cutter, namely:

• The value of the ampere-breaker capacitance (I): It is the one that separates the circuit when the load current exceeds the value of the breaker.
• Short current value (Isc): It is the maximum current value that the cutter can withstand without burning, and this value is increased the closer it is to the transformer according to (SC resistance).
• Sensitivity value (delta I): It is the value of the change in the current at which the circuit breaker is disconnected, in order to protect a person from electric shock when touching a metal object.

Ground leakage breaker connection

The process of connecting the ground leakage breaker is very easy and does not require much experience, you only need to connect the hot phase line to the input point of the phase with the letter (L) written on it, and connect the cold neutral line to the input point and the point of the cutter (N), while the output points of the cutter (L ,N) Connect with breakers or loads.

Jahzli website to buy electronics

When we say Jazli website, we are talking about one of the most famous Arab websites, which was able in a very short period of time to achieve a very high demand for purchases from it by people from different parts and sectors of the Arab world.

On the Jazli site, you will find Joint Lock and all the products that you may need in your home, starting with those for kitchens or bathrooms, but even those for gardens. You will find them in this wonderful site

So, if you were lost before and you don’t know where to go in order to buy your products on the Internet, now you have the perfect solution, and you only have to go to the Jazli website and start choosing the products you want.

What are the features of Jazli  ?

Since we are talking about a site that is preferred by many people around the world, there is no doubt that it is a site full of various features and characteristics, and for this we have decided to dedicate our next paragraph in order to indicate the most prominent features of the Jazli site.

Among the most prominent features of the site, we find that there is proportional prices. On the Jazli website, you do not have to worry about the imaginary prices of products, as is the case with most sites that display their products on the Internet.

The price of product delivery is very reasonable and not expensive, just as the site accepts delivery to various countries, without forgetting that it accepts free shipping on some products.

Among the advantages of the site, we also find that there is the high quality of its products, as it is impossible to find a poor-quality product. Rather, the Jahzli website deals with major companies, Philips, for example, and other famous brands, so you have to remove from your mind the idea of ​​poor quality of one of the products.

Also, one of the advantages of the site is that it does not specialize in one type of product, but rather you will find various types of products on it, for example, electrical appliances, hand tools, mechanical devices, paints, packages for establishing apartments and many other types.

Jahzli also accepts what is known as the shopping cart, which makes it easier for you to filter the products you want to buy and put them in one package in order to be able to pay with the click of a single button.

Multiple payment methods are accepted.
