Why Choose the Mersen A3T80 Class T Fuse?
The Mersen A3T80 is a compact, high-performance Class T current-limiting fuse designed to protect electrical equipment, conductors and power distribution systems against damaging overcurrent and short-circuit conditions. Manufactured as part of the Mersen Amp-Trap 2000 A3T series, this fuse combines a high interrupting capacity with a space-saving industrial design.
Rated at 80 A and 300 V AC, the A3T80 provides fast and reliable fault interruption in applications where available short-circuit currents may be extremely high. Its current-limiting operation helps reduce the peak let-through current and energy reaching downstream equipment, minimising thermal and mechanical stress on system components.
The compact Class T format makes the Mersen A3T80 particularly suitable for control panels, disconnect switches, distribution equipment, battery systems and industrial machinery where installation space is limited. It also carries a 160 V DC voltage rating, allowing it to be used in compatible direct-current circuits when installed in accordance with applicable electrical standards.

Reliable Protection for High Fault-Current Circuits
Current-limiting fuses such as the Mersen A3T80 interrupt dangerous overcurrents before they can reach their maximum prospective value. By limiting both peak current and let-through energy, the fuse helps protect cables, switches, busbars and connected equipment against severe thermal and mechanical damage.
The A3T series is designed for installations requiring high interrupting capacity in a compact footprint. Its Class T dimensions allow effective circuit protection to be incorporated into densely populated control panels, industrial equipment and power distribution assemblies without requiring the larger installation space associated with many conventional fuse types.
Typical Applications
- Industrial power distribution panels.
- Electrical disconnect switches and fused switches.
- Motor control centres and industrial machinery.
- Battery banks and compatible DC power systems.
- Uninterruptible power supply equipment.
- Commercial and industrial control panels.
