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.
