  • Essential time-saver for HVAC troubleshooting
The HUAREW Resettable Fuse Kit is an absolute must-have for anyone diagnosing low-voltage shorts in HVAC systems or appliances. Instead of wasting a handful of expensive fuses while trying to find a short, these 3 Amp and 5 Amp breakers allow you to simply reset with a single push after a trip. The UL listing for both 32V DC and 125/250V AC provides professional-grade reliability and peace of mind. I particularly appreciate the universal compatibility, as they easily replace popular tools like the Zebra ZK003 or Supco POP3. It’s a rugged, cost-effective solution that pays for itself after just one tricky service call. ... show more

  • Best troubleshooting tool
This was a great tool to use when I was working on my furnace and testing the 24v issues where it kept blowing my 3 amp fuse… Make sure to get one of these when troubleshooting issues with amp fuse blowing out!

  • Can have it reach anywhere and still have access to use it
Way easier than the fuses you find in heat pumps. The long leads make it easy to plug into your fuse port allowing you to not have to dig your fat fingers inside to reset it. Just used my 3amp one to diagnose a pressure switch clogged hose. Plugged it in powered it on quickly detached one side of the fuse to quickly put it back in. Closed circuit and gas burner started. Brand new pressure switch and still no ignition took me a second to find the clogged port. ... show more
