What Is a Fused Disconnect Switch?

Disconnect Switches

When making considerations for your commercial business’ electrical and overall preparation, safety is always a critical factor. You need a system that guarantees the safety of your employees, associates, and client’s—as well as safety for your assets and equipment.

What Exactly Are Disconnect Switches?

Both the device and its function are fairly simple and straightforward. These devices are a simple component that integrates with a particular electrical device or generator system. When applied, they will monitor the flow of electricity within the device. When dangerous fluctuations or interruptions are detected, your disconnect will, as you may expect, disconnect power to the tool, shutting off access safely before permanent harm or danger can arise.

There are two types of disconnect switches commonly used in commercial businesses: there are fused and non-fused (non-fusible). Today we’ll be discussing the former in hopes of helping you identify your specific needs better.

What Is a Fused Disconnect Switch?

The primary difference of the two most commonly used disconnect switches, fused and unfused, is all in the name. A fused disconnect switch allows for (and requires) the use of fuses to operate properly.

What’s a Fuse?

They certainly aren’t as common as they used to be, so we wouldn’t be surprised if you were unfamiliar. A fuse is a small glass cylinder in which there is a small filament of metal. The metal used in a fuse melts very quickly if something goes wrong, such as an electrical failure or surge, and if that happens, the filament will melt and the fuse will “blow”, immediately halting the operation of the electrical device.

There was a time when fuses were the standard, but modern advancements have moved on to the now more common breakers for electrical panels, which are now code.

Why Do I Need a Fused Disconnect?

Using a fused disconnect over a non-fusible one is largely based on a variety of factors that are unique to your business. What equipment you are using, your electrical power usage and capacity, and your current safety systems in place all play a vital role.

It is generally considered that a fusible switch is safer overall (due to the added protection of the fuse or fuses), and while this is sometimes true, there are many situations where a fusible switch cannot be used, is not compatible, or is simply unnecessary.
