Standard Blade Fuses, 20-100 Pack 2-50 Amp Fast-Acting Replacements for Automotive, Marine and HVAC Circuits
These standard blade fuses provide convenient fast-acting replacements for compatible automotive, marine, RV and HVAC circuits. Zinc-alloy elements offer dependable conductivity and corrosion resistance, while color-coded bodies help technicians identify the selected current rating quickly during diagnosis or routine fuse-box service.
Choose listed ratings from 2A through 50A in twenty- or one-hundred-piece packs. The documented 3A fuse supports 12V, 24V and 32V systems and measures approximately 0.75 by 0.2 by 0.75 inch. A blade fuse must match the original physical format and exact amperage; using a higher rating can leave wiring unprotected. Switch off the circuit, correct the cause of the blown fuse and install only the specified replacement.

Frequently Asked Questions
Can I replace a blown fuse with a higher amp rating?
No. Replace it only with the same fuse format and amperage specified for the circuit.
Which pack sizes are offered?
The variants include twenty- and one-hundred-piece packs in several current ratings.
Can the documented 3A fuse work in a boat or RV?
Yes, when the equipment calls for a standard 3A blade fuse within the stated 12V, 24V or 32V range.
Why are the fuse bodies different colors?
The color coding helps identify amperage, but the printed rating should still be checked before installation.
