Bussmann® Boric Acid Fuses BBU Medium Voltage General • The BBU power fuse is a Boric Acid, expulsion style fuse unit. • Provides a low initial cost alternative to refillable fuses in indoor applications. • Utilizes calibrated silver elements, boric acid for its interrupting media, and a spring & rod mechanism. • The housing is a fiberglass reinforced resin tube with plated copper contacts. • Available in 3 maximum voltage classes: 17kV, 27kV & 38kV • Available in 3 speed variations: E (Standard) SE (Slow E) & K (Fast) • Visual Indicating with use of end fittings. • End Fittings: • End fittings are required to complete the electrical connection between the fuse unit and the live parts and mounting. • The indoor fittings accept a Muffler attachment to limit noise and contamination to indoor equipment. The open fuse indicator located on the top end fitting provides visual indication on a faulted fuse unit.
