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.

Medium Voltage Expulsion Fuse

Fuse Class:

E (Standard), SE (Slow E) & K (Fast)

Voltage Rating:

17kV, 27kV & 38kV

Interrupting Ratings:

17kV - 14kA

27kV - 12.5kA

38kV - 10kA

Boric Acid, expulsion style fuses meet:

• ANSI C37.40 – Service Conditions and Definitions

• ANSI C37.41 – Power Fuse Design and Testing

• ANSI C37.42 – Distribution Fuse Ratings and Specifications

• ANSI C37.46 – Power Fuse Ratings and Specifications

• ANSI C37.48 – Power Fuse Application, Operations and

Maintenance

Applications

The BBU Boric Acid fuse provides effective protection for cir-

cuits and equipment which operate on voltage systems up to

34,500V. Typical usage is on industrial distribution systems for:

• Power Transformers

• Feeder Circuits

• Distribution Transformers

• Metal Enclosed Switchgear

• Pad Mounted Switches
