Review on Bussmann BP/CBB-30-RP: High-Performance 30 Amp Type-II ATC Blade Circuit Breaker by Cesar Carter

They definitely won't fit regular fuse holders, but damn I'm so tired of changing fuses every time I need to check a connection or something. These things work great! Stop wasting backups while working on something. I use mine to control the output of my air compressor for a set of train horns. I have connected a ViAir 450 to it and have been using them together successfully for about 3 months. So far no problems. See photos for a comparison of regular fuses and this switch and how I cut the holder to fit. The lid doesn't break on either side, but it's worth it in my opinion.
