The Bussmann NON‑15 is a reliable, general‑purpose, one‑time fuse engineered for basic overcurrent protection in circuits without high inrush currents. As part of the NON‑series Class K5/Class H family, it is designed for lighting circuits, main panel protection, and other applications where fast‑acting, non‑current‑limiting performance is appropriate. With durable construction and high interrupting capacity, the NON‑15 delivers dependable protection for residential, commercial, and light industrial electrical systems.

Key Features

• General‑purpose, one‑time fuse ideal for circuits not requiring time delay.
• Fast‑acting performance ensures quick opening during overcurrent events. 
• Non‑current‑limiting Class K5/Class H design suitable for basic branch‑circuit protection. 
• Non‑indicating style, cost‑effective and simple. 
• Cartridge fuse with ferrule ends, compatible with standard fuse holders. 
• Meets CE and UL/CSA compliance requirements for safety and performance.

Applications

The Bussmann NON‑15 is ideal for light‑duty circuits that do not experience large startup surges:

• Lighting circuits (residential, commercial, agricultural)
• Main fuse panel protection
• Non‑motor branch circuits
• Small appliances, general utility loads, and resistive heating circuits
• Circuits where quick response is required and time‑delay is not appropriate

This fuse is recommended for general‑purpose use where available short‑circuit currents are relatively low and where equipment does not require surge tolerance.
