Blowing disposable fuses during HVAC troubleshooting is expensive and inefficient. This fuse tester kit solves that problem with resettable breakers that can be reused multiple times. Instead of replacing fuses every time a circuit trips, simply reset and continue testing. The kit includes both 3 Amp and 5 Amp resettable fuses. Each is UL certified (Certificate QVNU2.E155159) and rated for 24V AC/DC and 125/250V AC, making them safe and dependable for HVAC service work. Compatible with HVAC systems, this fuse tester works with air conditioners, furnaces, compressors, and boards that use ATC 3A or 6A fuses. Installation is quick—plug into the fuse receptacle, use the adhesive backing for temporary mounting, and reset if tripped. This tool functions as a fuse checker, fuse popper replacement, and HVAC service accessory, giving technicians a practical way to diagnose without wasting fuses.
