Class T fuses and blocks

Class T fuses and blocks

Class T Fuse Blocks with Fuses

Use these single-pole fuse blocks to fuse inverters or other large loads. A 5/16" stud mount at each end of the fuse allows connection of a cable with a ring lug terminal end. To connect an inverter, order two cables with lugs on both ends: one to go from the battery to the fuse and one to go from the fuse to the inverter. Class T fuses exceed the 10,000 A interrupting capacity (AIC) required to protect Square-D brand circuit breakers in DC load centers. They are UL Listed for up to 160 VDC and NEC approved for inverter use. A fuse comes installed in the block. Order spare fuses separately.
