What is the definition of MCB?
MCB is an electromagnetic switching device made of insulating material. Like a typical plug-in Miniature Circuit Breaker, the Miniature Circuit Breaker can be opened and closed manually. Miniature Circuit Breakers are small trip switches that provide overcurrent protection. This overcurrent is an electrical fault caused by a short circuit and overload. MCBs are primarily used to protect appliances in residential, commercial and industrial electrical systems. Unlike fuses found mainly in older houses, mini Miniature Circuit Breakers have many advanced features. One of them is the highly reusable functionality of your electrical system in the event of a devastating electrical failure.
What does the Miniature Circuit Breaker do?
1. Magnetic function: In the case of short circuit, the flow current rating can rise to about 10 to 100 times the average current. When this happens, a strong magnetic field is created. Because the magnetic field is strong enough, it can be sensed by magnetic elements, which will immediately trip the Miniature Circuit Breaker. In addition, dangerous arcing may occur during short circuits. This arc is very harmful because it can escape into the air. In such cases, components within the MCB called arc ducts or arc suppression chambers are used to prevent such dangerous leaks. Arc channels are made of parallel plates that absorb dangerous arc and kill it, so they don't damage anything outside the circuit.
2. Thermal function: Overloads are caused by large amounts of electricity used in a single circuit. A common example of circuit overload is an excessive number of devices powered by and connected to extension cords. When the circuit is overloaded, the overcurrent rating is 2 to 5 times the normal operating current. This overcurrent is not as high as a short circuit, which is why magnetic elements cannot detect it. In other words, the failure can still cause damage. During circuit overload, the bimetallic plate in the MCB senses a sudden heat increase and causes the Miniature Circuit Breaker to trip.
What are the advantages of Mini-circuit breakers?
1. There are different types of MCBS that can be used for a variety of purposes. The most common type is the general purpose MCB, which is used in lighting applications and appliances, such as fans, compressors and pumps. Other types include motor circuit protection, overload protection, and leakage protection (ELC).
2. The MCB can be mounted on a DIN rail or screwed directly onto the panel. It also comes in different sizes and shapes for easy integration into existing systems and installations.
3. Mini-circuit breakers can be installed immediately after the installation of other electrical components without any modification.
4. The MCB is available in a variety of configurations, including unipolar, bipolar, and multipolar versions with low pressure (LV) and high pressure (HV) ratings. These products can be used in many applications, such as heating, ventilation, air conditioning systems, etc.
