A6T175 - 175 Amp Fuse

A6T175 - 175 Amp Fuse

The Mersen A6T175 Amp-Trap® Class T Fast-Acting Fuse is built for your electrical systems where dependable protection is not optional. Rated at 175 Amps, this Class T fuse helps protect your equipment from overloads and short circuits before they can lead to damaged components, unexpected shutdowns, or expensive repairs.

In busy commercial and industrial environments, electrical systems are under constant demand. When a fault occurs, the A6T175 is designed to respond quickly, helping reduce 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 equipment commonly used in power distribution systems and manufacturing facilities.

Another reason this fuse is widely used is its compact design. Panel space disappears quickly in many electrical installations, especially in retrofit projects or high-density equipment layouts. The A6T175 combines high current-limiting performance with a smaller footprint, making it easier to install where space is limited without sacrificing protection. Its Class T sizing also helps prevent replacement with lower-rated fuses, helping maintain proper system protection and safety standards.

Part of Mersen’s trusted Amp-Trap® A6T series, the A6T175 features a glass melamine body designed for dependable dimensional stability in demanding electrical applications. Permanently stamped catalog markings also make identification easier during inspections and maintenance work.

With a high 200 kA interrupting rating, the A6T175 is commonly selected for applications where high available fault currents are present and reliable overcurrent protection is essential.
