All Class-T fuses are not alike. This is one of the group of smaller Class-T fuses in the range from 110 - 200 Amps that fit in the Blue Sea 5007100 Fuse Block. This fuse wont fit in the larger Class-T fuse blocks.
We had to buy these from another supplier so our apologies that they cost more than they normally do.
