A6T1 - 1 Amp Fuse

A6T1 - 1 Amp Fuse

The Mersen A6T1 Amp-Trap® Class T Fast-Acting Fuse is designed to help protect your sensitive electrical equipment from overloads and short circuits before damage can occur. Rated at 1 Amp, this compact Class T fuse is commonly used in commercial and industrial electrical systems where dependable overcurrent protection and fast response times are important.

The A6T1 combines high current-limiting performance with a compact design, making it a practical option for applications where panel space is limited. When fault conditions occur, the fuse reacts quickly to help reduce the amount of fault current moving through the circuit. That fast action can help you protect control panels, transformers, disconnects, HVAC equipment, and other sensitive electrical components used in power distribution systems and industrial environments.

Part of Mersen’s Amp-Trap® A6T series, this fast-acting Class T fuse is designed to help prevent replacement with lower-rated fuses. The glass melamine body helps maintain dimensional stability in demanding electrical applications, while the permanently stamped catalog markings make identification easier over time.

With a 200 kA interrupting rating, the A6T1 is often used in industrial facilities, commercial buildings, power distribution systems, and control circuits where reliable fault protection is needed.
