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
• 
• Reomax believes in "customer first, sincere cooperation, continuous improvement and innovation", take continuing efforts in manufacture high quality products to meet the demands of users, and our goal is to become the "excellent circuit protection manufacturer".
