The Bussmann BP/MDL‑15 is an MDL Series time‑delay (slow‑blow) glass cartridge fuse engineered to provide reliable supplemental overcurrent protection for low‑voltage DC applications that experience temporary current surges. Manufactured by Bussmann (Eaton), this fuse is designed to deliver precise performance, durability, and dependable protection in demanding electronic and electrical environments.

Featuring a time‑delay operating characteristic, the BP/MDL‑15 allows short‑duration inrush currents—commonly associated with motor startups, transformer energization, and capacitive charging—to pass without nuisance interruption. When exposed to sustained overloads or fault conditions, the fuse responds reliably to open the circuit, helping prevent damage to wiring, components, and connected equipment.

The glass tube construction allows fast visual inspection of the fuse element, enabling quick identification of blown fuses during troubleshooting or routine maintenance. Nickel‑plated brass end caps provide secure electrical contact and corrosion resistance, contributing to consistent long‑term performance.

Built in the industry‑standard 1/4 inch x 1‑1/4 inch (3AG) size, the BP/MDL‑15 fits widely used fuse holders and clips for easy installation and replacement. Packaged conveniently in a 2‑count retail card, it is well‑suited for maintenance inventory, service work, and replacement applications.
