Circuit Breaker Explained

Circuit Breaker Explained

Overcurrent and short circuits can damage electrical circuits if circuit breakers are not installed. 

As part of its primary function, it interrupts current flow to protect equipment from damage and reduce the risk of a fire.

Unlike a fuse, which can only be used once before needing to be replaced, a circuit breaker can be reset (manually or automatically) to resume normal operation.

Also, they are made in varying sizes, from small devices that protect low-current circuits or individual home appliances—providing up to large switchgear that is designed to protect high voltage circuits for an entire city.

A circuit breaker, or fuse, also known as an Over Current Protection Device, is a device that automatically cuts power to faulty systems when triggered. Let’s further look at the factors to consider when buying a circuit breaker.

Factors To Consider When Buying A Circuit Breaker

Factors To Consider When Buying A Circuit Breaker

Here are some factors to consider when buying a circuit breaker with distinct features:

Voltage Rating

Circuit breakers need to have enough voltage capacity to handle the application’s needs. However, the overall voltage rating is calculated by the highest voltage that can be applied across all end ports.

Frequency

The higher the ampere rating in specific frame size, the greater the rating required. Circuit breakers up to 600 amps can be applied to 50-120 Hz frequencies. Frequencies higher than that will end up with the breaker having to derate.

Hence, it is necessary you confirm the frequency before buying one for yourself.

Maximum Interrupting Capacity

The breaker will be damaged if the correct amount of interrupting capacity is not applied. 

As a result, it is critical that you follow the unbreakable rule that follows when using the proper circuit breaker.

The interrupting capacity of the breaker must be equal to or greater than the amount of fault current that can be delivered at the point where it is applied, according to this rule.

The interrupting rating is commonly accepted to be the maximum amount of fault current that the breaker can interrupt without causing system failure.

Price

The most important factor is working with your budget. Remember that you can get a perfect circuit breaker that will serve practical purposes and is also very affordable to purchase.

Other factors include;

Continuous current rating,

Atypical Operating Conditions, and

Maintenance and Testing.
