Title: BUSS HRC Fuse 440mA Tear Down !!
Post by: Kiriakos GR on October 06, 2012, 08:18:07 PM

No matter how many times you will turn the WWW upside down, you will never see a HRC fuse tear down.  ;D

The ITTSB.EU have performed this unusual tear down for educational purposes.

1) As you can see in the pictures bellow, the fuse metal ends are made by true copper.

2) The fuse end are actually a cover of another copper plate, which haves connected on it the inner bridge wire.

3) The fuse is full of white sand, with looks more close to sugar.

4) BUSS added an inner spacer to keep the inner bridge wire totally aligned.

Now you know more than yesterday  :)  Share this link among your friends.  ;)
