Cooper Bussmann ATM-25 Fast Acting Mini Blade Fuse 25A

Product Description

The COOPER BUSSMANN ATM-25 is a fast-acting mini blade automotive fuse rated at 25 amps and 32 volts DC. It is designed to protect automotive electrical circuits and low-voltage control circuits from overcurrent damage by opening rapidly when current exceeds the rated amperage. The ATM-25 measures 0.43 inches in length with an overall height of 1.58 inches and a width of 0.15 inches. The housing is constructed of polyamide with zinc terminals and elements finished in silver plating. Licensed technicians and automotive electricians install this fuse as a direct service replacement or during new circuit builds.

The ATM-25 is suited for 12-volt and 24-volt automotive electrical systems as well as low-voltage control circuit applications. Its mini blade form factor fits standard mini blade fuse holders found throughout passenger vehicles, light trucks, powersport equipment, and marine ignition-protected applications. It is appropriate for both OEM circuit protection and aftermarket fuse panel installations where the ATM mini series is specified.

Key Features

• Fast-acting response protects sensitive automotive electronics from overcurrent damage
• Mini blade style fuse — fits all standard mini blade fuse holders
• 25 amp rating at 32 volts DC
• Polyamide housing with silver-plated zinc terminals for corrosion resistance
• Meets ISO 8820-3, JASO D612, SAE J2077, SAE J1171 ignition protection, RoHS, and UL Listed (Guide FHXT, File AU169)
• Replaces Littelfuse MIN025 and Ferraz Shawmut AF2-25

Compatibility

The ATM-25 is a direct replacement for the Littelfuse MIN025 and the Ferraz Shawmut AF2-25. It is compatible with any standard mini blade fuse holder accepting ATM-series fuses in automotive and low-voltage control circuit applications.

Installation Notes

Installation of blade fuses is typically performed by automotive technicians or electricians working on low-voltage control circuits. Always disconnect the vehicle battery or de-energize the circuit before replacing a fuse. Verify that the replacement fuse amperage matches the circuit rating exactly — never substitute a higher-amperage fuse to resolve repeated blowing, as this indicates an underlying fault requiring diagnosis. Follow applicable SAE and manufacturer wiring guidelines for ignition-protected installations.
