A6T100 - 100 Amp Fuse

A6T100 - 100 Amp Fuse

The Mersen A6T100 Amp-Trap® Class T Fast-Acting Fuse is built for your electrical systems that need quick, dependable protection when fault conditions happen. Rated at 100 Amps, this Class T fuse helps protect valuable equipment from overloads and short circuits before they turn into costly downtime or damaged components.

In busy commercial and industrial environments, electrical protection is not something most people think about until there is a problem. That is where the A6T100 comes in. Its fast-acting design responds quickly to fault currents, helping reduce the amount of energy that reaches connected equipment. That added protection can help extend the life of  your transformers, control panels, disconnects, HVAC systems, and other electrical equipment used every day in power distribution systems and industrial facilities.

One thing that makes the A6T100 stand out is its combination of high current-limiting performance and compact size. In crowded electrical panels, every inch matters. This fuse is designed to provide strong protection without taking up unnecessary space. Its Class T design also helps prevent replacement with lower-rated fuses, which can help maintain proper system protection.

The glass melamine body is built for dependable dimensional stability in demanding environments, while permanently stamped catalog markings make identification easier during inspections and maintenance work. With a high 200 kA interrupting rating, the A6T100 is a practical choice for applications where high available fault currents are present and reliable overcurrent protection is essential.
