Why Choose the Mersen A3T1 Amp-Trap Class T Fuse?
The Mersen A3T1 is a compact, fast-acting Class T current-limiting fuse designed to protect electrical circuits and equipment against damaging short circuits and overcurrent conditions. As part of the established Mersen Amp-Trap® A3T series, it combines rapid fault interruption with a high breaking capacity for dependable protection in industrial and commercial power systems.
This fuse offers excellent current-limiting performance, reducing the peak current and energy that pass through a circuit during a fault. Its compact cartridge design enables high-performance protection to be installed where panel space is limited, while its rejection-style dimensions help prevent the use of unsuitable fuse classes in compatible holders.
With a rated current of 1 A, a maximum voltage rating of 300 V AC and a 160 V DC rating, the Mersen A3T1 is suitable for control circuits, power distribution equipment, industrial machinery and electrical panels requiring fast and reliable circuit protection.

Reliable Current-Limiting Circuit Protection
Current-limiting fuses such as the Mersen A3T1 interrupt severe fault currents before they reach their maximum prospective value. This reduces the electrical, thermal and mechanical forces placed on cables, control components and connected equipment during a short circuit.
The compact Class T format provides a high interrupting capacity in a relatively small enclosure. This makes the A3T series particularly useful for control panels, distribution assemblies and industrial equipment where dependable fault protection and efficient use of installation space are essential.
Typical Applications
- Industrial machinery and automation equipment.
- Electrical control panels.
- Power distribution systems.
- Control transformers and auxiliary circuits.
- Lighting and heating control equipment.
- Power conversion and rectifier equipment.
- Commercial and industrial electrical installations.
