Amazon Affiliate Link: https://amzn.to/4kpXkcQ Price as reviewed: $18 (for two, 1x 5amp, 1x 3amp) WRUHG-POP3 POP5 Fuse Protectors 3 Amp and 5 Amp Circuit Breaker Fuse Testers Rated 24V DC and 125/250V AC These resettable circuit breakers come with about 18" of wire that have blade terminals on the end, so you could use them to replace a blade fuse while testing circuits. (Or you could cut the terminals off and wire them permanently). They have a 1" square of double sided adhesive foam on the back for mounting to a flat surface, or you can panel mount them with the included nuts. They also include a "push to reset circuit breaker" panel mount label that goes around them, and include a rubber "water protection" cover. In my testing with a high power battery, they tripped immediately. It took a few seconds for the internal mechanism to cool down and reset before you could push the top button down to re-latch / re-set them. I pushed 3 amps of DC current through a short and the 3 amp breaker didn't trigger for the 5 minutes I tested it, so they appear to carry the rated current without issues, even when shorted with a current supply. There are two stickers on these guys. One is on the side and looks very professional. (It has the 32 volt DC or 125/250 volt AC rating and some other marks). The white sticker on the front says the breaker is UL listed, but does not include a UL listing number or a UL official graphic. It also looks like it was made with a wide label printer [So...as to the UL listing....I doubt...]
