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.
