Types of Circuit Breakers Explained

Circuit Breakers Explained

When it comes to circuit breakers, the first thing that should come to your mind is circuit protection. These automatic electrical switches are put in place in order to protect a circuit from excess current. A circuit breaker knows to spring into action when it detects a fault, and does this by interrupting current flow. Without these handy devices, the chances of fires or other electrical issues would skyrocket! A circuit breaker functions a lot like a fuse (see "What Is A Fuse?" for more info) except instead of needing to be replaced after a circuit interruption, a circuit breaker can be used time and time again. Basically, there is a piece of metal in the breaker. When this piece of metal is heated to extreme temperatures, this causes the breaker to “trip.” When the piece of metal in the circuit breaker cools down, it can be reset again. This is how a breaker is built to last longer than a normal fuse.

Types of Relays Explained

Posted by Kelsey on Oct 18, 2017 9:09:00 AM

Puzzled by the seemingly endless types of relays roaming around?

Well you're in luck as we decided to take a look into 5 common relay types in order to simplify this seemingly daunting topic. 

Basically, many people see a relay as a switch. The main difference between a relay and a switch  is that a switch is operated mechanically while a relay is operated electrically. Although this is a pretty general description, each relay follows this same basic principle. Where things start to differ is with the smaller details between each type of relay. Read on to decode the purposes of these relays and figure out which one is right for you!

Confused on what's in a relay? Check out Del City's blog post to get some in depth information on the technical aspects of these products!

What Is A Fuse?

Posted by Lauren on Dec 2, 2016 12:52:00 PM

What is a fuse? Simply put, it's your first line of defense against a short circuit. 

When a circuit experiences an excessive amount of current flow, fuses heat up and blow to protect the circuit from damage, such as fires. Usually, fuses are found close to the battery in order to avoid battery damage from a direct short in the cables coming off the posts. Often times you'll find one larger fuse block closer to the battery, and then have the circuit branch out further away with additional, smaller fuse blocks.

Fuses function similar to circuit breakers, except circuit breakers are often more accessible. Typically, engineering schematics will dictate when and where you'll need to use fuses versus circuit breakers.
