What is the breaking capacity of the fuse? Sounds like it may be a low breaking capacity fuse. If it is you should change it to a high breaking capacity fuse. From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of Boštjan Glavic Sent: Tuesday, August 06, 2013 12:46 AM To:

Bostjan commented: During the abnormal tests in primary circuit, internal input fuse operates and glass breaks. However, fuse is inside the tubing and broken glass does not spread around. Would you accept such construction? - - - - - Bostjan, Such a question can have

When a fuse's interrupting (breaking) capacity is too low for an application and the fuse opening interrupts current in a manner that causes the glass to crack or break, the temperature gradient across the glass and the internal pressure created by the plasma when the fusible element vaporized can
