Efficient HVAC Diagnostics with a Resettable Fuse Tester

When troubleshooting circuit breakers in busy HVAC systems, you need a tool that helps you identify abnormal conditions without wasting fuses. The BOJACK 3A/5A Resettable Fuse Tester is designed to detect overloads, undervoltage, and short circuits, and to automatically interrupt the circuit to protect fuses. It supports both 24V AC/DC and 125/250V AC environments and carries UL certification for reliability in professional settings.

The compact all black insert type tester fits neatly into breaker receptacles and provides clear feedback during testing. The included 18 AWG test wires with 250 terminals ensure secure connections in tight panels, while a top mounted reset button lets you quickly restore normal operation after a test. This streamlined workflow can help you move through diagnostic steps with less re-wiring and fewer fuse replacements.

Key benefits you can expect

  • Save fuses: automatic interruption during overload, undervoltage, or short circuit situations helps prevent unnecessary fuse blows.
  • Easy operation: plug in the terminals, test the breaker, and press reset to resume normal use after a trip.
  • Broad compatibility: designed for 24V AC/DC and 125/250V AC systems, suitable for HVAC panels, appliances, generators, and more.
  • Practical kit: includes 3A and 5A breakers, wiring, and hardware; self-adhesive backing supports temporary installation on breakers.

  • Widely applicable: compatible with central air conditioners, home and commercial equipment, marine systems, and HVAC diagnostics.
  • Reliable construction: UL listed and designed for temperatures from -10°C to 60°C, suitable for job sites and workshops.
