KNOW YOUR FUSES

In order to select the proper protective device, the following parameters and criteria need to be considered:

1. What is the normal operating current of the circuit?
2. What is the operating voltage?
3. Is the circuit AC or DC?
4. What is the operating ambient temperature?
5. Is the device being used for short-circuit
protection, over-load protection, or both?
6. What are the physical size limitations?
7. Does the fuse need to be "field-replaceable"?
8. Is resettability an issue?
9. How will I mount the device?
10. What are the cost considerations?
 

How will the fuse be mounted?

One of the most careful considerations that need to be made is the mounting of the fuse in the circuit. There are several options at hand:

1. Direct Solder: In this method, the fuse is directly soldered into or onto the printed circuit board (PCB). The drawback to this design is the lack of field replaceable parts as discussed in great detail in the above section but cost can be significantly reduced with this mounting method.

2. Fuse Clips: Fuse clips are relatively inexpensive and allow for field replaceability. Fuseclips are typically mounted on a PCB so any attempt at replacing the fuse will require opening of the piece of equipment by the end-user. Additionally, removing a fuse from a fuse clip without disconnecting the power source could lead to an electrical shock when touching the fuse. Fuse clips are available for all "tube" fuses as well as microfuses. Typically fuseclips are limited to 20A of normal current (also available in 30A). Fuse clips are generally not listed or recognized by any safety agencies.

3. Panel Mounted Fuseholders: Panel mounted fuseholders allow for easy access for the end-user to replace the fuse in the field. The panel mount fuseholder is shock-safe meaning that the fuse is removed safely when the cap of the fuseholder is removed preventing the possibility of electrical shocks. Fuseholders are typically tested and approved by safety agencies such as UL and CSA. Fuseholders are typically available up to 30A.

4. Fuse Blocks: Fuse blocks are like fuse clips however they do not need to be mounted on the PCB. Fuses mounted in fuse blocks are typically only accessible by opening the piece of equipment which could lead to electrical shocks if the equipment is not disconnected from the power source. Fuse blocks are one of the few methods to mount fuses of large amperage. 5. Inline Fuse Holders: Inline fuse holders are typically used as a part of a wire harness assembly or where no surface is available to secure another type of fuse mount. Inline fuse holders are generally available up to 100A in lower voltage applications and up to 30A in higher voltage applications.
