Overview
The Bussmann NON-100 is a general-purpose, non-current-limiting one-time fuse engineered for basic overcurrent protection. With 100 A rating and 250 VAC/125 VDC voltage capability, this cartridge fuse is ideal for circuits that do not experience temporary surges. It protects lighting, heating, and other circuits not subject to temporary surges where available short-circuit currents are relatively low.
Key Features
- Class K5 and H fuse classification for standard circuit protection
- One-time (non-renewable) fuse design with medium/normal blow speed
- 10 kA interrupting rating for reliable fault clearing
- UL, CE, and CSA listed for safety compliance
- Cartridge blade form factor for standard fuse holders
- Non-current-limiting design for general-purpose applications
Technical Specifications
The NON-100 meets industry standards for Class H fuses and is suitable for legacy and new installations requiring basic overcurrent protection without surge suppression.
Typical Applications
- Lighting circuits in residential and light commercial installations
- Heating equipment and furnace protection
- General-purpose motor circuits without high inrush requirements
- Control circuits and low-surge electrical systems
- Legacy panel upgrades and replacements where Class H fuses are specified
