The BP/NON‑40 Cartridge Fuse from Bussmann Corporation is a fast‑acting, general‑purpose overcurrent protection device designed for dependable use in residential, commercial, and light industrial electrical applications. As part of the established NON series, this fuse is intended for circuits where immediate fault interruption is required and time‑delay characteristics are not necessary.

Rated at 40 amps and 250 volts AC, the BP/NON‑40 provides rapid response to overload and short‑circuit conditions, helping protect conductors, electrical components, and connected equipment from damage due to excessive current. Its fast‑acting, one‑time operation makes it well suited for circuits with steady or resistive loads where high inrush currents are not expected.

The fuse features a compact cylindrical cartridge body with ferrule‑end terminations, ensuring reliable installation in compatible fuse holders and blocks. This retail‑carded version includes two fuses per package, making it a convenient option for replacements, service work, or maintenance inventory.
