Class T fuses 450–600 A
The Class T fuses (also called T-fuses) FT-450, FT-500 and FT-600 protect main circuits with very large lithium-ion battery banks and inverters at 450, 500 or 600 A. Their interrupting capacity is 20,000 A at 125 V DC. They are mounted in the fuse holder 778-T2S-600 B, which you can order directly with the fuse from philippi in Remseck am Neckar, Germany.

Frequently asked questions. Answered briefly.
Which fuse holder fits 450 to 600 A?
The fuse holder 778-T2S-600 B is intended for the Class T fuses FT-450, FT-500 and FT-600. It is rated for 125 V DC and supplied with cover but without fuse. The studs are 3/8" (Ø 10 mm) with a stud spacing of 52 mm. You can order it directly with the fuse on this page.
What are Class T fuses used for?
Class T fuses are preferably used to protect lithium-ion batteries, because these can deliver extremely high currents in a short circuit. With an interrupting capacity of 20,000 A at 125 V DC, the fuse still disconnects reliably and protects cables and loads from the consequences of a short circuit.
Which ratings are available below 450 A?
philippi offers Class T fuses in three groups, each with its own holder: 110 to 200 A with holder BS 5007100, 225 to 400 A with holder BS 5502100 and 450 to 600 A with holder 778-T2S-600 B. We are happy to help you choose the right rating for your electrical system.
