Boric Acid Fuses
Medium Voltage
BBU
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 inter-
rupting 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 fit-
ting provides visual indication on a faulted fuse unit.
