The BP/FNM‑15 from the Bussmann Division is a time‑delay (slow‑blow) cartridge fuse designed to provide dependable overcurrent protection for circuits that experience temporary inrush or startup currents. Rated at 15 amps and 250 volts, this fuse is engineered to withstand short-duration current surges while opening safely under sustained overload or fault conditions.

Part of the Bussmann FNM series, the BP/FNM‑15 features a rejection‑type cartridge design, which helps prevent the installation of incorrect fuse classes and improves overall system safety. Its time‑delay characteristics make it particularly well suited for motor loads, transformers, solenoids, and inductive equipment commonly found in residential, commercial, and light industrial applications. Packaged in a 2‑count retail card, this fuse is ideal for service, maintenance, and replacement needs.
