NH KNIFE BLADE
NH fuses are typically used for power
distribution applications and to protect
large electrical devices such as motors,
drives, etc. They are available in seven
sizes with a current range of 2 to 1600
Amps.
NH fuses have knife blades at both ends,
which mount into Fuse Bases. Fuse
Bases are available in one or three pole
designs and can be panel or DIN rail
mounted.
