What are Electric Circuit Breakers?

An electrical circuit breaker is an electronic switch used to protect and regulate the electrical power supply. It can be controlled manually or automatically. The design of the circuit breaker in the modern power system has been altered in response to high currents and to avoid arcing while in use.

Knowing your primary circuit breaker panel is essential for carrying out any installation or maintenance involving electricity in your house. Circuit breakers are small switches found in electrical panels that, for safety purposes, halt the flow of power. They are also known as tandem breakers or double pole breakers.

Types of Circuit Breakers

Circuit breakers with low amperages and low to medium voltages are necessary for residential dwellings and multi-housing units.
Medium- to high-voltage circuit breakers are necessary for apartment buildings and utility companies due to the amount of power they supply to the public.

Factors To Consider Before Buying Electric Circuit Breakers

When thinking about buying or replacing electric circuit breakers, efficiency, and safety must come first. Circuit breakers are essential because they identify problems and instantly cut off electricity when there is a power surge or other issue, protecting your house or place of business. Consultation with professionals is recommended before beginning this job to guarantee the task is completed safely and accurately.
Furthermore, knowing the significant factors listed below will help you make a well-informed choice.

AMPERAGE LABELING

The needed amperage is always marked on circuit breakers. To guarantee that the circuit breakers are appropriate for your electrical system, it is essential to match the total amps in the breakers with the designated amperage. This step is essential for guarding against overloads and making sure the circuit breakers are operating correctly.

TESTING AND MAINTENANCE

It is imperative to do routine testing on circuit breakers, particularly in regions with severe weather, to guarantee their proper operation and ease of upkeep. Timely resolution of issues is crucial, and professional maintenance services or repairs must fix any problems found during testing.

MAXIMUM INTERRUPTING CAPACITY

Businesses with higher electrical demands should use higher Maximum Interrupting Capacity (MIC) circuit breakers. They can interrupt current up to a maximum of a certain amount, which is typically necessary for appliances and electronics. Electronics and appliances could need a higher MIC, particularly in situations where several devices are being utilized at once.

VOLTAGE RATING

A circuit breaker’s voltage rating is essential for safety since it guarantees that it will trip safely when an overload occurs. High-voltage choices for power lines are available in business circuit breaker types. To avoid explosions or arcing in the event of a short circuit, look for a circuit breaker that is rated at least as high as the open-circuit voltage.

FREQUENCY

Another crucial element is frequency, which should be less than 60 Hertz. The frequency range of most circuit breakers is between 50 and 60. Frequency over 60 Hz usage might weaken the circuit breaker and lower its power rating. Your circuit breaker may suffer damage and premature aging from a reduced power rating.

SETUP

The performance and longevity of a circuit breaker are highly dependent on the installation conditions. Its capacity to fend off electrical surges may be compromised by exposure to intense heat, sunshine, or dampness. For maximum functionality, it is crucial to put circuit breakers in settings that reduce these factors.

Safety Measures To Take Before Installation

Some safety measures to remember before installing your electric breakers are as follows:

Be sure of your surroundings

Make sure the surrounding areas are dry before beginning any electrical work. Turn off any appliances that are powered by the circuit breaker that will be replaced to reduce the possibility of electrical dangers.

It is best to install protective enclosures

To ensure the long-term protection of your breaker panel, install an electrical power cover enclosure. This will reduce unintentional contact by acting as a barrier against exterior factors. Utilize circuit breaker lockout hardware to enhance safety when doing installation or maintenance.

Prefer seeking professional assistance

Seeking professional services is advised if doubts emerge about the specifics of various types of breakers. Expertise is required for electrical maintenance, repair, and installation operations; specialists are equipped with the necessary knowledge and experience to carry out these duties safely and effectively. Using a professional service guarantees that the task is completed per safety regulations.

FAQs About Electric Breakers

What Amperages do we offer?

At Sevenco, we offer circuit breakers ranging from 15 amp to 500 amp.

What are the two main standard circuit breakers?

The two main types of standard circuit breakers are-

  • Single-pole: These breakers have ratings of 120 volts and 15-20 amps
  • Double-pole: These breakers are made up of two single-pole breakers with ratings between 15 and 200 amps.

What are the three basic types of circuit breakers?

The three basic circuit breaker types are–

Standard Breakers (including single-pole and double-pole), Ground Fault Circuit Interrupter Circuit Breakers (GFCIs), and Arc Fault Circuit Interrupter Circuit Breakers (AFCIs).

Are double electric breakers safe?

Absolutely. As long as they are installed in panels that can accommodate them and by manufacturer instructions, double or tandem breakers are safe and acceptable to use.

Can you mix brands of breakers in a panel?

Combining different brands of circuit electric breakers in the same electrical panel is generally not advisable. Every brand of circuit breaker is made to fit into a particular panel and may have unique compatibility criteria and trip characteristics. Combining different brands might negate warranties and pose safety risks.

What is MCCB used for?

MCCB are known as Molded Case Circuit Breakers. These are breakers used in high-power applications such as those in large industries or businesses. Such breakers can be used up to 2500 A.

What is an industrial breaker?

An industrial circuit breaker is a very important part of electrical safety systems in industries. Industrial breakers are used to break the electrical circuit when an overload of electricity occurs. Some of these have automatically operating switches that are designed to protect against potential fire hazards or any damage to the electrical circuit of the industry.

How long do circuit breakers last?

A circuit breaker typically lasts between thirty and forty years. This does not negate the need for you to check your breakers, though periodically.

When does a circuit breaker need to be replaced?

A faulty circuit breaker might result in power being turned off unexpectedly or failing to turn off the power when it should. Flickering lights, faulty linked electronics, unexpected burnt-out bulbs, burned-out smells, melted wiring, frequent break-outs, and excessive heat coming from the breaker panel are typical symptoms. If any of these indicators exist, get assistance from an expert electrician.
