The BP/MDL‑1/2 from Bussmann Corporation is a time‑delay (slow‑blow) glass cartridge fuse designed to provide dependable overcurrent protection for sensitive electrical and electronic circuits that experience temporary inrush currents. Rated at 1/2 amp (0.5 A) and 250 volts AC, this fuse is ideal for applications that require protection against sustained overloads while avoiding nuisance opening during normal equipment startup.

As part of the trusted Bussmann MDL series, this fuse uses a dual‑element time‑delay design that allows short‑term current surges commonly associated with motors, transformers, power supplies, and other inductive loads. The clear glass tube construction enables quick visual inspection for blown fuses, simplifying troubleshooting and maintenance.

The BP/MDL‑1/2 features a standard 1/4 in × 1‑1/4 in cartridge size, ensuring compatibility with a wide range of common fuse holders. Packaged in a convenient 2‑count retail card, this fuse is well suited for service technicians, maintenance departments, and replacement inventory in residential, commercial, and light industrial environments.
