Selection of the Fuse and Holder Solution

The first step is to answer the following questions:

• Will the fuse need to accessible for replacement?
• How often will the fuse need to be replaced?
• Should the end customer of the appliance have access to change the fuse?
• Should the fuse only be accessible from outside the appliance?
• How much is available to spend on safety and reliability?

5.1.2. Requirements and characteristics

The most important standards for fuse-holders, which specify requirements, characteristics and testing methods are:

• IEC-publication 257 (1968) and Amendment no. 2 to this publication dated January 1989.
• UL-standard no. 512.

• 
• Company warehouse
•
