Why Choose the Mersen A3T200 Amp-Trap® Class T Fuse?
The Mersen A3T200 is a fast-acting Class T current-limiting fuse designed to protect industrial and commercial electrical systems against damaging short circuits and overcurrent conditions. As part of the established Mersen Amp-Trap® A3T series, it combines high current limitation with compact dimensions to provide dependable protection for conductors, switchgear and connected equipment.
The A3T200 features unique Class T dimensions that help prevent substitution with fuses offering lower voltage ratings or reduced current-limiting performance. Its durable glass melamine body provides excellent dimensional stability, while the catalogue number is permanently stamped into the copper blades for clear identification during installation and maintenance.
Rated at 200 A, 300 V AC and 160 V DC, the Mersen A3T200 is suitable for panelboards, switchboards, load centres, metering centres and industrial power distribution equipment where rapid fault interruption and efficient use of enclosure space are essential.
