A3T200 - 200 Amp Fuse

A3T200 - 200 Amp Fuse

The Mersen A3T200 Class T Fuse is built for electrical systems that need fast response and dependable protection. With a 200A rating and fast-acting performance, this fuse helps protect equipment from short circuits and overloads before damage spreads through the system. It’s a common choice for commercial and industrial applications where keeping equipment protected and minimizing downtime are important.

Because it’s a Class T fuse, the A3T200 offers strong current-limiting protection in a compact size. That smaller footprint makes it easier to install in panels and equipment where space is limited. Even with its compact design, it still delivers a high 200 kA interrupting rating, helping handle high fault current conditions safely.

The fuse features a glass melamine body for added durability and dimensional stability, along with copper blade terminals for secure bolted connections.

Whether you're protecting power distribution equipment, UPS systems, motor controls, or industrial panels, the A3T200 is designed to provide consistent overcurrent protection in demanding electrical environments.
