Circuit breakers are an electrical device that is used to automatically break a path that has become overloaded. They are used to prevent major fires or electrical disasters to your home or business as a safety precaution. In order to decide what breaker is the perfect choice for your needs you will need to consider the voltage that you will be using, the point at which you wish the circuit to trip and the overload protection needed.

The most common type of breaker that is used is a low voltage breaker which is ideal for residential use. There are several different types of breakers, low voltage are just the most common. Low voltage circuit breakers are easy to install because using them only requires the installation of one general breaker panel.

There are other types of circuit breakers including miniature circuit breakers, molded case circuit breakers, medium voltage circuit breakers and high voltage breakers. Depending on your need, commercial or residential, will depend on which type of breaker will be best for you.

Miniature circuit breakers are the lowest voltage breaker that is available. They are known to carry electricity of only 100 amps. Miniature circuit breakers are capable of holding electrical charges of no more than 1,000 amps.

Molded case circuit breakers are the ideal breaker for 1,000 amps of electricity. They safely disconnect when that goes beyond ten times the capacity. They are often called magnetic circuit breakers. They are called this because they use electromagnetic power solenoid’s to break the circuit when the flow exceeds capacity.

A medium voltage breaker has a capacity of between 1,000 and 72,000 amps before they break. The performance is relative to which brand and model you choose. You will often see these breakers used in larger buildings and businesses. You will find them in cabinets indoors and switchboxes which are enclosed. There are three breaker sub types within the medium voltage breaker category: SF6, air and sub-type breakers.

High voltage circuit breakers are those that are capable of holding more than 72,500 volts of electricity. These breakers are usually found outdoors with high voltage power lines. These circuits are controlled with a solenoid switch that activates the arc-chamber when too much electricity flows through.

When considering a breaker it is important to consider the voltage as well as the trip point. The trip point when the breaker will trip should be set at a point comfortable that it prevents your wiring from overheating. When your breaker is overloaded you want to be sure it trips and electricity current is no longer flowing. This is crucial to prevent major electrical accidents and fire from overloaded circuits.
