A6T25 - 25 Amp Fuse

A6T25 - 25 Amp Fuse

The Mersen A6T25 Amp-Trap® Class T Fast-Acting Fuse is a solid choice for protecting your electrical systems where quick response and dependable performance matter. Rated at 25 Amps, this Class T fuse is designed to help protect circuits from overloads and short circuits before they lead to damaged equipment or unexpected downtime.

In commercial and industrial settings, electrical systems are constantly working behind the scenes to keep operations moving. When a fault occurs, the A6T25 reacts quickly to help limit the amount of fault current passing through the circuit. That fast action can help you protect transformers, control panels, HVAC equipment, disconnect switches, and other sensitive electrical components commonly found in power distribution systems and manufacturing environments.

One thing that makes the A6T25 especially practical is its compact size. In crowded electrical panels where every inch matters, this fuse delivers high current-limiting performance without taking up unnecessary space. Its unique Class T dimensions also help prevent replacement with lower-rated fuses, helping maintain proper system protection and safety standards.

Part of Mersen’s trusted Amp-Trap® A6T series, the A6T25 features a glass melamine body designed for dependable dimensional stability in demanding electrical applications. Permanently stamped catalog markings also make identification quicker during inspections and maintenance work.

With a high 200 kA interrupting rating, the A6T25 is commonly used in applications where high available fault currents are present and reliable overcurrent protection is important.
