Square D Breakers

More Information about Square D Breakers

Another popular line of residential circuit breakers is the Homeline series. Like the QO series, these breakers are also used frequently for their dependability and affordability. The features of a Homeline breaker are very similar to those found in a QO breaker but at an about-half-the-price rate. They’re suitable for new homes, home renovations, and buildings undergoing remodeling or construction.

The Square D range also includes specialty breakers, such as arc fault circuit interrupters (AFCIs) and ground fault circuit interrupters (GFCIs). AFCIs are designed to protect against electrical fires. They work by detecting the kind of sudden increase in current associated with an arc fault. GFCIs work by protecting against ground faults—a common cause of electrocution. Both types of breakers are available from Square D.

FAQs

Where can customers purchase or access Square D parts and products?

Customers can purchase or access Square D parts and products through distributors such as RSP Supply.

Is a Schneider circuit breaker the same as a Square D circuit breaker?

No, a Schneider circuit breaker and a Square D circuit breaker are not exactly the same, but Square D is a brand owned by Schneider Electric, meaning Square D breakers are part of Schneider's product line, primarily used in North America with specific designs and standards.

Breakers vs Fuses 

Fuses

Fuses are safety devices that are intended to provide protection to both equipment and people in the event of a power surge or an overcurrent situation. A fuse can provide this protection by using a small piece of wire that is sacrificial, and is intended to burn up when too much current is passed through it. When this happens, the fuse eliminates the flow of electricity in that circuit until it is replaced. The size and type of wire that is used in the fuse will dictate how much current can pass through that individual fuse. So the main thing to remember is, when a fuse blows, it must be replaced and cannot be reused. 

Circuit breakers

Circuit breakers are intended to be reused after they are “tripped” during a power surge or an overcurrent situation. Much like fuses, circuit breakers are designed to trip at a certain current level. This is intended to protect both equipment and anyone in the area of that particular circuit. Circuit breakers can be found in just about any variation from single phase, low current applications to three phase, and high current applications.

As a general rule: fuses are more simplistic and reliable. They cost less initially and are better suited for individual circuit protection. However, they can create more cost over time with each use and may create hazards due to the exposed connection points. Whereas circuit breakers offer better branch circuit protection and do not need to be replaced after each use. They are more expensive initially and, because of their complexity, are more prone to failure over time.
