About this item

Bussmann NON‑20 — 20A General‑Purpose One‑Time Class K5/H Cartridge Fuse:

The Bussmann NON‑20 fuse is a dependable, general‑purpose cartridge fuse designed for light‑duty and branch‑circuit protection where reliability and simplicity are essential. As part of Bussmann’s long‑established Class K5/Class H NON‑series, this fuse delivers safe, consistent overcurrent protection for circuits that do not experience heavy motor loads or large inductive surges. Engineered as a one‑time, non‑current‑limiting fuse, the NON‑20 provides fast‑acting response to overcurrent conditions, ensuring the protection of wiring, equipment, and electrical infrastructure in residential, commercial, and light industrial environments.

Constructed with durable materials and thoroughly tested to meet UL and CSA safety standards, the NON‑20 fuse represents a cost‑effective, versatile choice for panelboard circuits, lighting loads, appliances, and other low‑demand electrical systems. Its ferrule‑end cartridge design enables easy installation, straightforward replacement, and compatibility with standard fuse holders—making it ideal for maintenance operations, electricians, facility managers, and manufacturers who need simple and reliable circuit protection.

Key Features

  • General‑purpose one‑time fuse designed for basic overcurrent protection where equipment does not require time‑delay performance. 
  • Fast‑acting design that opens quickly during fault events to protect wiring and connected equipment.
  • Non‑current‑limiting Class K5/Class H construction, offering straightforward protection for low‑demand circuits.
  • Ferrule‑end cartridge format for simple insertion and removal during installation or replacement.
  • Compact 2″ × 0.56″ cylindrical form factor suitable for a wide range of standard fuse blocks and holders.
  • Non‑indicating style, providing cost‑efficient protection without added indicator mechanisms.
  • CE‑marked and UL/CSA listed, ensuring compliance with widely recognized electrical safety standards.

Applications

The Bussmann NON‑20 fuse is ideal for general‑purpose electrical systems that do not contain large inductive loads, motors, or equipment requiring time delay. Typical installations include:

  • Lighting circuits commonly used in residential, commercial, and agricultural settings. 
  • Main fuse panel protection where one‑time, fast‑acting response is appropriate. 
  • Branch circuits with stable, predictable current characteristics and minimal starting surges. 
  • Small appliances, pumps, and utility circuits requiring standard overcurrent protection. 
  • General‑purpose circuit protection in light‑industrial, commercial, and residential power distribution systems.

This fuse is especially suitable for locations where simplicity, affordability, and fast protection outweigh the need for time‑delay or circuit‑limiting characteristics.
