Bussmann 1B0031U Fuse

The Bussmann 1B0031U fuse is a 30-amp, 600-volt overcurrent protection device from Bussmann (now Eaton Bussmann). Identified by the catalog number 1B0031U, this fuse is designed to interrupt fault currents in circuits operating at voltages up to 600 V when current exceeds 30 A, helping safeguard conductors and equipment from overloads and short circuits. As part of the Bussmann line, it reflects the brand’s emphasis on reliable protection for electrical systems across industrial and commercial installations. The 1B0031U designation locates this exact part for replacement in systems that specify this model and rating, enabling precise matching to your schematic and components. When selecting a replacement, ensure your circuit requirements align with a 600 V maximum and a 30 A interrupting device to maintain proper protection without exceeding voltage or current limits.
