The NTN-R-100 is a dummy fuse neutral designed for use in electrical systems requiring neutral placeholders. It is rated for 250V operation and accommodates the R/H fuse equivalent dimension, making it compatible with standard fuse holders in this class. The product is specified for the 70-100A amp size range, providing appropriate sizing for mid-range current applications. Dummy fuse neutrals are non-functional fuse-shaped components used to occupy neutral positions in fuse blocks or panels where actual fuses are not required. This product is commonly used in industrial electrical installations and panel configurations where neutral protection or placeholder requirements must be met.
