Frequently Asked Questions (FAQs)

1. Why do fuse holders melt?

Heating in an electrical circuit is always caused by current flowing through a resistance. If there is significant resistance in the contact between fuse and fuse holder, a current well below the fuse rating can cause enough heat to melt an inline fuse holder.

2. What are the different types of fuse holders?

Electronic fuse holders can typically be grouped into four different categories: Printed Circuit Board (PCB) Fuse Clips, Printed Circuit Board Fuse Holders, Panel Mount Fuse Holders and In-Line Fuse Holders.

3. What is a rejection style fuse holder?

A rejection feature is used to prevent fuses with a lower voltage or interrupting rating (such as Class H and Midget fuses) from being used in a circuit that needs a higher rating. Class R and CC fuseblocks incorporate a built-in rejection feature while Class J and T blocks reject based on physical size.
