What Are the Types of Circuit Breakers?

What are the main types of circuit breaker? Basically, there are three main types of circuit breakers. They are distributed, control and circuit breakers. This article will explain briefly each type, so you can get an idea how they work. This may give you an idea what kind of breaker would suit your needs best.

The first main type of circuit breaker uses the concept of heat removal; the basic principle is that the oil filled in the inlet of the device is heated up and pushed to the outer terminal when the circuit is tripped. When the oil is removed, the appliance will shut down automatically. The major advantage of this type is that there is no need for an oil lubricant which makes it the cheaper choice. The main disadvantage is that when the oil reaches its maximum temperature, an arc can form and interrupt the power flow altogether.


The second type is HVDC circuit breakers. The HVDC (heater voltage multiple circuit breaker) uses a couple of conductors, one on the input and one on the output to regulate the heat transfer across the contacts. The process is similar to the oil lubricant case, but the dissimilarity lies in the fact that there is no need for lubrication on the part of the device where the regulation is taking place. Due to the dissimilarity in the principle, the dissimilarity also results in some advantages and some disadvantages. For instance, it is easier to install HVDC circuit breakers because of their simpler structure.


The third main type is the multi zone electrical power systems breaker. These use the MZ Circuit Breaker, which is the most complicated one among all. It is designed to protect three different areas of the power distribution system: Load Antenna, Loadline, and Interior Lighting. Basically, MZ circuit breaker has two terminals: the lower terminal of the circuit breaker, which control the lower load limit, and the upper terminal that control the high load limit. The load limit is dictated by the lower and the upper limit of electrical power.


The fourth type is the plain air circuit breakers which can either be the distributed or the closed circuit system. A distributed system is installed where there are several zones of protection. On the other hand, a closed system is simply an air blast circuit breaker with only one terminal. It is usually installed where the circuit will be isolated from the surrounding environment.


The next type is the AGP (agi voltage) standard circuit breakers. It is considered to be the safest type of this kind of breaker. It works by detecting the difference in voltage between the interior and exterior circuits. Once it detected the voltage difference, it will interrupt the power supply. The reason why this type is considered safer compared to other kinds of this device is because it can detect even small discrepancies in voltage.


The last type is the vacuum breaker. This kind of circuit breaker uses the vacuum field around its contacts. This will stop electricity when the contacts are touching each other. It detects the contact that is made with a higher or lower resistance than its normal level. Due to this, there is a small drop in voltage on the exterior circuit. Its advantage is that it does not have any contacts on its surface, so the electricity it can detect is quite large.


These are just a few of the known types of electrical circuit breakers available in the market today. Of course there are more to discover. Some people use a combination of different kinds of electrical devices in their homes. That is why it is important to know more about the different kinds of electrical devices you can use in your home.
