Class T fuses protect cables and components in high-power DC systems against overcurrent and short circuits.
They are particularly suitable for lithium battery systems, inverters, and DC main distribution panels.

Typical applications include solar storage systems, off-grid systems, and mobile and marine power systems in RVs, adventure vehicles, and on boats and yachts.

Why Class T, and which fuse is right for you?

In the event of a fault, lithium batteries can deliver very high short-circuit currents. Class-T fuses react quickly and limit the current, thereby reducing the load on cables and downstream components. Their high DC breaking capacity makes them particularly suitable for high-power battery systems.

The appropriate fuse rating depends on the maximum operating current as well as the rated currents of the cable, battery, fuse holder, and connected devices. Additionally, the maximum DC voltage and the possible short-circuit current of the system must be taken into account.
