Cooper Bussmann ATM-3 Fast Acting Mini Blade Fuse 3A 32V

Product Description

The COOPER BUSSMANN ATM-3 is a fast-acting mini blade automotive fuse rated at 3 amps and 32 volts DC. Designed for overcurrent protection in automotive electrical systems and low-voltage control circuits, this fuse uses a zinc terminal and element housed in a polyamide body with silver-plated contacts. At 0.43 inches in length, it fits the standard ATM mini blade footprint found throughout modern vehicle wiring harnesses. Licensed electricians, automotive technicians, and equipment service pros install this fuse type during circuit repair, panel service, and control circuit protection work. It meets ISO 8820-3, JASO D612, SAE J2077, SAE J1171 ignition protection, RoHS, and UL Listed standards.

The ATM-3 is suited for passenger vehicles, light trucks, marine equipment, and other 12-volt and 24-volt low-voltage control circuit applications where a mini blade fuse format is specified. Its fast-acting response provides immediate overcurrent interruption to protect sensitive automotive electronics and wiring. Typical install locations include under-dash fuse panels, inline fuse holders, and auxiliary circuit protection blocks. The ATM series is a widely used mini blade format across domestic and imported vehicle platforms.

Key Features

• Fast-acting fuse element for immediate response to overcurrent events
• Mini blade (ATM) form factor fits standard automotive fuse panels and inline holders
• Polyamide housing with zinc terminal and element for durable, corrosion-resistant performance
• Silver-plated contacts for reliable low-resistance connections
• Compliant with ISO 8820-3, JASO D612, SAE J2077, SAE J1171, RoHS, and UL Listed (Guide FHXT, File AU169)
• Violet color coding for quick 3-amp identification at the fuse panel

Compatibility

The ATM-3 is a direct replacement for Littelfuse MIN003 and Ferraz Shawmut AF2-3. Designed for automotive fuse panels and low-voltage control circuits requiring a fast-acting mini blade fuse at 3 amps and 32 volts DC.

Installation Notes

Installation should be performed by a qualified automotive technician or licensed electrician. Disconnect the vehicle battery or de-energize the circuit before replacing any fuse. Always replace with a fuse of identical amperage and voltage rating. Do not install a higher-amperage fuse to resolve a repeated blowing condition — diagnose the underlying circuit fault first.
