Introduction of switchgear and their range of applications<\/strong><\/h3>\n

\u2013 Switching equipment, also known as Aptomat, this is a group of many products including many different categories with many different functional uses, different according to each category: ACB, VCB, MCB , RCCB, RCBO, ELCB, RCD.<\/p>\n

For each type of product, there are very different purposes of use, that's why we would like to summarize the basic information so that you can understand the concept as well as the name and scope of use of the product. each device type.<\/p>\n

1. Air breaker:<\/strong>ACB (Air circuit breaker)<\/h4>\n

For high voltage, air-extinguished arc current up to 3000Amps at 415V. This type of switchgear is often used for protection on transmission lines, in power plants.)<\/p>\n

2. Vacuum cutting machine<\/strong>: VCB(Vacuum Circuit Breakers)<\/h4>\n

With this type of vacuum switch, they are usually used for high voltage, use vacuum for arc extinguishing, mostly used in voltage levels 415 volts.6.6 KV,10 KV,33 KV,110 , range micro use is for protection on transmission lines, in power plants)<\/p>\n

3. MCCB<\/strong>: (Moulded case circuit breaker)<\/h4>\n

This is a block type amplifier, this type of product usually has a very large short-circuit current (up to 80kA).<\/p>\n

The range of use is commonly used with low voltage networks, and at the present time MCCB has reached the threshold of breaking current of 2400A.<\/p>\n

\"Thi\u1ebft<\/p>\n

4.MCB<\/strong>: (Miniature Circuit Bkeaker)<\/h4>\n

Shrimp type Aptomat is the common name of this switch product, they have the outstanding feature of having a rated breaking current and a low overload current (100A\/10kA).<\/p>\n

Common applications of this type are for small loads, they are capable of breaking up to a maximum current of 100A.<\/p>\n

5. RCCB<\/strong>: (Residual Current Circuit Breaker)<\/h4>\n

This type of current switch is used to prevent leakage currents of sizes MCB 2P, 4P.<\/p>\n

The main use of this type is to switch and protect against leakage currents to protect against shock for people, and to prevent fire and explosion of equipment.<\/p>\n

6. RCBO<\/strong>:(Residual Current Circuit Breaker with Overcurrent Protection)<\/h4>\n

This is also a type of switch like RCCB, but they are only 2P MCB size, in addition, they also have built-in overcurrent protection.<\/p>\n

The type is used to switch and protect against leakage current to protect against electric shock for people, and to prevent explosion of equipment.<\/p>\n

7. ELCB<\/strong>: (Earth Leakage Circuit Breaker)<\/h4>\n

This is a type of switch with integrated leakage current protection, in essence, it is the same MCCB introduced above, but has been improved with a leakage current sensor.<\/p>\n

With this type, they have very versatile features, both short circuit protection, overload protection, leakage current protection, so the cost is very high, dozens of times higher than RCCB.<\/p>\n

The type is used to switch and protect against leakage current to protect against electric shock for people, and to prevent explosion of equipment.<\/p>\n

8. RCD<\/strong>:(Residual Current Device)<\/h4>\n

Is a device that is always attached (attached) to MCCB or MCB to protect against leakage current (it is actually an ELCB).<\/p>\n

type used to switch and protect against leakage current to protect against electric shock for people, fire and explosion for equipment.<\/p>","protected":false},"excerpt":{"rendered":"
