Cooper Bussmann DIA-1 Atc Fuse Diagnostic Kit

Product Description

The COOPER BUSSMANN DIA-1 is an ATC blade fuse diagnostic kit designed for automotive and low-voltage electrical system troubleshooting. The kit includes six ATC blade fuses rated at 5, 10, 15, 20, 25, and 30 amps, along with the FP-3 fuse tester and puller tool. Together, these components let an electrician or service technician identify blown fuses, safely extract them, and install replacements without additional tools. Each fuse measures 0.73 inches long, 0.39 inches wide, and 0.14 inches high. The compact format makes it practical for a service vehicle or toolbox where space is limited.

This kit is suited for electrical service work on vehicles, light equipment, and low-voltage control circuits that use the standard ATC blade fuse format. Typical applications include automotive fuse panel service, trailer wiring, HVAC equipment control circuits, and any low-voltage system protected by ATC-style blade fuses. The included FP-3 tester eliminates the need for a separate continuity tester when diagnosing fuse-related faults in the field. Package quantity is 5 units per order.

Key Features

Compatibility

Designed for use with standard ATC blade fuse holders found in automotive fuse panels and low-voltage control circuits requiring fuses rated from 5 to 30 amps.

Installation Notes

Always de-energize or disconnect the power source before removing or replacing a fuse. Use the included FP-3 puller to remove fuses rather than pulling by hand to avoid blade damage. Follow NEC and applicable low-voltage wiring standards when servicing control circuit fuse panels. Verify the replacement fuse amperage matches the circuit rating before restoring power.
