A circuit breaker is a specially designed switch that will protect the wiring of the house or the commercial buildings during short circuit or overload. It will automatically detect if there are any faults in the electricity distribution and will stop the flow of current.

There are different types of fuses available in the market. All of them have unique specification and features that selection of the best one can get really tough. Here are a few things you have to consider to assure that you have selected the right thing.


The voltage of the panel switch is calculated with the help of the highest amount of voltage that can be distributed across all the end ports. You must beware of the distribution types and the direct integration of the circuit breaker into the system. To meet the end application, it is important that you select the circuit breaker with the required voltage capacity.


The most common types of circuit breaker have almost 600 amps and it can operate the frequency of 50 to 120 Hz. You will have to reduce the power rating of the breaker if you want the frequency to be higher than that. Pay attention towards the requirements of appliances that you will be using in the commercial building to assure that your circuit breaker will match their frequency.

Maximum interrupting capacity

It is regarded as the highest amount of the fault current that the breaker can stop. You have to assure that the interrupting capacity of the circuit breaker is slightly less than what the appliances can tolerate. It will enhance the life of the electrical products because they will not have to suffer the extra voltage and the damages that come with it.


With the advancement in technologies, many innovations have been introduced in the circuit breakers. Here are some of the most commonly used and famous technologies available that you can select from:

  • Thermal
  • Thermal magnetic
  • Magnetic
  • Magnetic hydraulic
  • Electronic
Operating conditions

One of the most important things that you have to consider regarding the circuit breaker is the operating conditions listed on the item. There are certain temperatures and voltages that have been mentioned. Remember that the circuit breakers are manufactured under strict environment and the conditions mentioned on them might not match our atmosphere. So you have to be very careful regarding the circuit breaker and fuses that you are selecting for your commercial building or machinery.

Bottom line

The installation of the panel switch is not an easy task. There are certain points in the building where they can be installed and only the experts will know. It is important that you hire the professionals and get their advice during the selection of the fuses because they will give you the best idea. Select the product that will meet your requirements and your budget. The high-tech and latest items will be more durable and competitive as compared to the old items.
