  • Bussmann by Eaton is packaging their fuses in a whole new way: Fuses Made Simple. The

  • fuses to my right are the branch circuit fuses. These are the UL class rated fuses, proved

  • by UL to use for a branch circuit protection anywhere on the circuit. These fuses here

  • to my left are the control circuit fuses. They don't have a class rating; they're more

  • supplementary-type fuses that supplement the class rated fuses.

  • Bussmann had 49 different label designs and 10 different fuse families. We know its a

  • challenge sometimes to figure out what fuse do I use for the right application. We came

  • up with Fuses Made Simple: we went from the 49 label designs and 10 fuse families down

  • to four.

  • As you can see, you have the yellow, green, black and gray fuses. These four fuse families

  • now make up the entire branch circuit protection of Fuses Made Simple within Bussmann. The

  • four different fuse families provide three different levels of protection. The color

  • coding that you see on the fuses indicate a level of protection that is provided. The

  • yellow fuse, which is our ultimate level of protection, that is the low peak family of

  • fuses. That provides the highest level of protection that you can get.

  • The middle two, both the green and black one, fall under the second level of protection,

  • what we call advanced level. The green fuse is a Fusetron, that is a time delay fuse.

  • The black one is a Limitron fuse, and that is a fast-acting fuse. The time delay fuses

  • are going to be used in what's called inductive loads, loads such as motors, transformers,

  • relays, etc. When you turn them on, they have what's called an initial inrush of current.

  • That time delay feature allows that inrush to occur and then operate at it's level again.

  • The fast-acting fuse, on the other hand, is more for resistant loads, such as lighting,

  • heaters, things of that nature, where there is no inrush of current. It just goes right

  • to its operating level and its operating fine. Lastly is our basic protection, our general

  • duty basic fuse which meets the basic requirements of the NEC for overcurrent protection.

  • On the control circuits, sometimes referred to as supplementary fuses, the branch circuit

  • is more power applications. The control circuit is providing protection to the controller,

  • not carrying main power. This is more very application design specific. There also is

  • a color coding here, now the color coding is not by performance as you see with the

  • branch circuit. With this one, the color coding is by voltage.

  • Whether you're selecting the branch circuit or the control circuit, what you'll find is

  • that now it looks like a Bussmann fuse, the only difference really are the colors.

  • How to select a control circuit fuse is pretty easy, there's just three steps. First step

  • is: what application? Is it time delay or is it fast-acting? That's the first question.

  • The second question is: what voltage do you need? The third question is: what interrupted

  • rating do you need? Once you know those three things, you can quickly and easily select

  • a fuse. The whole purpose of coming up with the Fuses Made Simple program is to enable

  • a customer or an engineer to select and specify the right fuse the fastest.
