The Bussmann NON‑30 is a general‑purpose, fast‑acting (one‑time) cartridge fuse designed for protecting lighting circuits, heating loads, and other non‑motor electrical systems. Part of the Bussmann NON Series, this fuse provides reliable overcurrent protection where circuits do not experience motor inrush or inductive surges. It is commonly used in residential fuse panels, commercial electrical systems, agricultural equipment, and light‑industrial branch circuits.
