Mersen Ferraz Shawmut 60306T Fuse Block – 30A, 600V, 1-Pole, Class T, Small-Footprint

The 60306T is engineered specifically for Class T fuses, which are roughly one-third the size of standard Class RK or Class J fuses. The "T" in the part number indicates the rejection feature; the clips are spaced and shaped so that only a Class T fuse can be installed. This ensures that the high-speed, current-limiting characteristics required for the circuit are maintained.
