Why Choose the Mersen A3T700 Amp-Trap Class T Fuse?
The Mersen A3T700 is a high-capacity Amp-Trap 2000 Class T fast-acting fuse designed to protect industrial electrical equipment, switchboards and power distribution systems against damaging overcurrent and short-circuit conditions. Its advanced current-limiting design rapidly interrupts fault currents, helping to minimise thermal and mechanical stress on downstream equipment while improving overall system protection.
Rated at 700 A, 300 V AC and 160 V DC, the Mersen A3T700 combines exceptional interrupting performance with the compact dimensions of a Class T fuse. Its unique physical design prevents substitution with lower-performance fuse classes, improving electrical safety and coordination.
The A3T700 is widely specified for switchboards, panelboards, load centres, industrial machinery and electrical distribution systems where dependable high-current protection is essential.
