The Offgridtec Class T fuse is a fast-acting, high-current fuse for high-power DC systems. It is available in rated currents ranging from 110 to 400 A and is suitable for battery, solar, and inverter systems, as well as electrical installations in RVs and boats, among other applications. With a DC breaking capacity of 20 kA, it is designed for applications where high fault currents must be safely interrupted.

Current-limiting design
Compact Class T design
Operating temperature: -40 to +120 °C
Two sizes for 110–200 A and 225–400 A
Fast protection for high-power DC systems
The Class T fuse protects DC circuits from excessively high currents and short-circuit events. With a DC breaking capacity of 20 kA, it is particularly suitable for high-power battery systems, inverters, and central DC distribution systems. The selection of the appropriate fuse rating must be based on the conductor cross-section, operating current, and connected components.
13 current ratings from 110 to 400 A
The series is available in 13 rated current variants: 110 A, 125 A, 150 A, 175 A, 200 A, 225 A, 250 A, 275 A, 300 A, 325 A, 350 A, 375 A, and 400 A. This allows the fuse to be selected to match the specific electrical configuration of the DC circuit.
Two sizes depending on the rated current
The variants from 110 to 200 A have a total length of 62 ± 0.5 mm and a hole spacing of 43 mm. The versions from 225 to 400 A are larger, with a total length of 70 mm and a hole spacing of 46.9 mm. When selecting a fuse holder, therefore, the appropriate size must be taken into account in addition to the rated current.
