A6T3 - 3 Amp Fuse

A6T3 - 3 Amp Fuse

The A6T3 Class T Fast-Acting Fuse is the kind of component you install when you don’t want to think twice about protection. It’s built for situations where a circuit fault needs to be handled immediately—no delay, no second chances. At 3 amps, this Amp-Trap® fuse is designed to react fast and shut things down before sensitive equipment takes the hit.

What makes it useful in real-world applications is how much protection it delivers in such a small footprint. The Class T design is compact, but it’s built to handle serious fault current levels—up to 200kA interrupt capacity. That matters in panels and power systems where space is tight but the risk level is high.

The ferrule-style construction also helps here. It fits cleanly into clip-mounted holders and reduces the chance of incorrect substitution thanks to its unique dimensions.
