A3T1 - 1 Amp Fuse

A3T1 - 1 Amp Fuse

The Mersen A3T1 is a fast-acting Class T fuse designed to help protect your electrical systems from overloads and short circuits before they can cause damage. Rated at 1 amp, this compact fuse is commonly used in applications where equipment protection and quick response times are important. Its small size makes it easy to install in control panels and other tight spaces without giving up performance.

Built with a glass melamine body and copper ferrule terminals, the A3T1 is made for dependable operation in industrial and commercial environments. The fuse also features high current-limiting capability, which helps reduce the amount of energy that passes through the circuit during a fault condition. That added protection can help minimize damage to connected equipment and reduce downtime. Because it’s rated for both AC and DC systems, the A3T1 works well across a wide range of electrical applications.
