Why Choose the Mersen A3T110 Amp-Trap® Class T Fuse?
The Mersen A3T110 is a compact, fast-acting Class T current-limiting fuse designed to protect industrial and commercial electrical systems against damaging short circuits and overcurrent conditions. Part of the established Mersen Amp-Trap® A3T series, it provides rapid fault interruption and effective current limitation to help protect cables, switchgear and connected electrical equipment.
The A3T110 combines a high interrupting capacity with a compact Class T format, making it suitable for installations where reliable protection must be achieved without occupying excessive panel space. Its current-limiting performance reduces the peak current and energy passed through the circuit during a fault, helping minimise thermal and mechanical stress on downstream components.
With a rated current of 110 A, a 300 V AC rating and a 160 V DC rating, the Mersen A3T110 is ideal for panelboards, switchboards, load centres, industrial machinery and power distribution equipment requiring dependable, high-speed circuit protection.

Reliable Current-Limiting Circuit Protection
Current-limiting fuses such as the Mersen A3T110 interrupt severe fault currents before they reach their maximum prospective value. This reduces the electrical, thermal and mechanical forces placed on conductors, switchgear and connected equipment during a short circuit.
The compact Class T design provides a high interrupting capacity within a relatively small enclosure. This makes the A3T110 particularly suitable for industrial distribution systems where dependable fault clearance, equipment protection and efficient use of panel space are essential.
Typical Applications
- Industrial panelboards and distribution panels.
- Switchboards and electrical switchgear.
- Load centres and metering equipment.
- Industrial machinery and control systems.
- Power distribution assemblies.
- Commercial electrical installations.
- Power conversion and battery systems.
