A6T150 - 150 Amp Fuse

A6T150 - 150 Amp Fuse

The Mersen A6T150 Amp-Trap® Class T Fast-Acting Fuse is designed to help you protect electrical systems from overloads and short circuits before connected equipment can be damaged. Rated at 150 Amps, this Class T fuse is commonly used in commercial and industrial applications where dependable overcurrent protection helps keep your systems operating safely and reduce unplanned downtime.

The A6T150 responds quickly during fault conditions, helping limit the amount of fault current moving through the circuit. That fast action can help you protect transformers, control panels, disconnects, HVAC systems, switchboards, and other electrical equipment used in power distribution and manufacturing environments.

One advantage of the A6T150 is its combination of high current-limiting performance and compact physical size. In electrical panels where space is limited, this fuse provides dependable protection without taking up unnecessary room. Its unique Class T dimensions also help prevent replacement with lower-rated fuses, helping maintain proper system protection.

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

With a high 200 kA interrupting rating, the A6T150 is often used in applications where high available fault currents are present and reliable fault protection is required.
