The NON‑45 is a general‑purpose, one‑time, non‑current‑limiting fuse designed for light‑duty electrical circuits. It provides basic overcurrent protection where fault currents are relatively low and no motor inrush or time‑delay capability is required.

Key Features

• One‑time fuse (no time‑delay).
• Non‑current‑limiting design, appropriate for circuits without large temporary surges.
• Non‑indicating—no blown‑fuse visual indicator.
• Ferrule‑end cartridge suitable for standard fuse holders.
• Class H / Class K5 fuse classification.

  • 50 kAIC at 125 VDC
• Body Style: Cartridge fuse, ferrule end × ferrule end
• Dimensions:
  • Length: 3 in
  • Diameter: 0.81 in
• Weight: ~0.1 lb

Applications

Suitable for circuits without high inrush demands, including:

• Lighting circuits
• Heating loads
• General‑purpose branch circuits

This fuse should not be used in motor circuits or surge‑heavy environments due to its lack of time‑delay capabilities.
