A6T225 - 225 Amp Fuse

A6T225 - 225 Amp Fuse

The Mersen A6T225 Amp-Trap® Class T Fast-Acting Fuse is built for your electrical systems that need quick, dependable protection when fault conditions happen. Rated at 225 Amps, this Class T fuse helps protect valuable equipment from overloads and short circuits before small electrical issues turn into costly downtime or damaged components.

In many commercial and industrial facilities, electrical systems operate around the clock. When a fault occurs, the A6T225 responds quickly to help limit the amount of fault current moving through the circuit. That fast action can help you protect transformers, switchboards, HVAC equipment, control panels, disconnects, and other sensitive electrical components commonly found in power distribution systems and manufacturing environments.

One thing electricians and maintenance teams appreciate about the A6T225 is its compact design. Panel space is not always easy to come by, especially in retrofit projects or crowded industrial enclosures. This fuse delivers high current-limiting performance without taking up unnecessary room, making it easier to maintain a clean and efficient panel layout. Its Class T sizing also helps prevent replacement with lower-rated fuses, helping maintain proper circuit protection and safety requirements.

Part of Mersen’s trusted Amp-Trap® A6T series, the A6T225 features a glass melamine body designed for dependable dimensional stability in demanding electrical applications. Permanently stamped catalog markings also help make identification quicker during maintenance and inspections.

With a high 200 kA interrupting rating, the A6T225 is commonly used in applications where high available fault currents are present and reliable overcurrent protection is essential.
