Review on GLOSO E37 Auto (T1) Reset Low Profile ATC/ATO Circuit Breakers - (5A - 20 Pack) by Eric Speers

I found the trip point accurate, they trip on over current and reset when the overload is removed within a minute (cooling). I love this device. They are available in different amperages. So far I've only tested the 10 amps. This is much more convenient than replacing blown ATO fuses. I used mine on a southbound fuel pump - about every 10 hours of use a 10 amp ATO fuse would blow. I replaced the fuse with one of these. Of course it opened up after a few hours of use and reset itself automatically when I turned off the pump for a few minutes. The pump then ran fine for a few more hours (until I replaced it).
