More information:

Why choose a glass fuse?

Glass and ceramic fuses have similar properties. Glass fuse is great for small items that don't draw a heavy amount of current and blow on a regular basis. It is easy to identify whether the fuse has blown as you can see inside it.

What size is it?

5x20 mm is a standard cartridge size and it measures approximately 20 mm long by 5 mm in diameter. They are popular in board and panel protection and will fit a compatible 5x20 fuse holder.

What Speed is it?

This particular fuse is ''F'' speed rated which means a fast acting fuse. These are designed to protect less sensitive components and are also used to protect cabling from melting or catching fire when an overload appear. Every fast acting fuse will have the exact speed stated which will be relevant to different overloads.

What are fuses used for?

• For the protection of components and equipment from costly damage caused by over-current.
• To isolate sub-systems from the main system once a fault has appeared

What is an over-current?

It is a setting where a circuit experiences a current that is higher than the normal operating current.
