A Buyer's Guide to Circuit Breakers

Many modern electronics and devices count on the management of current running throughout circuits to achieve proper functionality and safety, with equipment known as circuit breakers playing a major role in protecting various sensitive components and reducing hazards. While there are a number of circuit protection devices that one may use for safeguarding systems, circuit breakers are highly reliable options that are commonplace in homes, businesses, and even vehicles. In this blog, we will provide an introduction to circuit breakers, covering their functionality, common types, and how they compare to other options.

What are Circuit Breakers and How Do They Work?

As a form of electrical safety device or switch, circuit breakers are designed to automatically halt the flow of electricity when it detects an overload condition or short circuit. This ensures that the circuit is protected from damage, deterring the chance of overheating, fires, and other various hazards.

One of the most notable features about circuit breakers is how they can be reset after they trip, allowing for a user to restore system functionality without having to replace any parts. This allows them to reliably protect a wide variety of circuits, devices, systems, and appliances across applications.

Common Types of Circuit Breakers

Several types of circuit breakers exist on the market, each with its own set of unique characteristics and applications. Below, we will share details on some of the most common options that one may come across.

Standard Circuit Breakers

Standard circuit breakers are considered the most common type, regularly being found within residential and commercial buildings for safeguarding against overloads and short circuits. Standard circuit breakers are generally separated into two distinct subcategories, which are single-pole and double-pole breakers.

Single-Pole Breakers

With a single-pole breaker, lighting and general-purpose outlets can have protection rated upwards of 120 volts. These breakers are easily identifiable by a single switch that can be reset after a short circuit or if overload occurs.

Double-Pole Breakers

With a double-pole breaker, two circuits can be protected at the same time with a rating of up to 240 volts. These breakers feature a double-wide switch to bolster their capabilities, allowing them to effectively serve high-power appliances like stoves and hair dryers.

Ground Fault Circuit Interrupter (GFCI) Circuit Breakers

Ground fault circuit interrupter (GFCI) circuit breakers are necessary for upholding protection against ground faults that occur when electricity flows through an unintended path to the ground, which makes such equipment beneficial for wet areas like bathrooms and kitchens. These breakers are most notable by the test and rest button that may be featured on an outlet or device.

Arc Fault Circuit Interrupter (AFCI) Circuit Breakers

Arc faults are a condition in which unintended electrical discharges occur, a hazard that may lead to fires or injury. To safeguard living spaces and other areas against this, arc fault circuit interrupter (AFCI) circuit breakers may be used, as they leverage advanced electronics for rapid detection and response.

Combination Arc Fault Circuit Interrupters (CAFCI)

Combination arc fault circuit interrupters (CAFCI) are a specialized option that can provide both GFCI and AFCI protection, providing the highest level of safety for circuits. These breakers are becoming increasingly common in new constructions and homes with their comprehensive abilities.

Circuit Breakers vs. Fuses

As fuses are one of the most common protection devices alongside circuit breakers, it can be useful to bring both into the discussion to compare their differences. While fuses similarly impede the flow of electricity when conditions are bad, they do so in a sacrificial manner by melting and breaking down. While fuses must be replaced each time, they do come with the benefit of being cheaper and reliable, commonly working alongside breakers and other devices.
