I repair machines that use use them for a living, they are cheap
protection. they definetely nuisance trip for no reason. oh well it
keeps me working

they are so commonly used because of being so cheap. but it would be
far better if a resettable kind were used. lots of perfectly good
stuff must be tossed every year because a thermal fuse fatigued
failed.

I service roll laminating machines for a living. sael, GBC, Laminex,
USI, Idex, Ledco. Sadly nother manufacturer Banner just went out of
business after 38 years.

the economy is far worse than were being led to believe...............:
