Medium Voltage Fuses
Bussmann is a leading expert in the design, development and manufacture of medium voltage fuse links and their associated accessories and supplies fuses to 90 countries worldwide, playing an integral role in the international standardisation of medium voltage fuses.
Bussmann’s medium voltage fuses offer unparalleled short-circuit interruption capabilities and are used by electrical utilities and switchgear manufacturers throughout the world. Eaton’s Bussmann Series medium voltage fuses are safe, reliable and cost effective making them the protection device of choice for distribution circuits due to their speed of operation and current limiting ability.
BBU Boric Acid Fuses
17kV, 27kV, 38kV
Bussmann’s Boric Acid Fuses for power transformers, feeder circuits, distribution transformers, metal enclosed and pad mounted switchgear. The Boric Acid Fuses have a voltage rating of up to 38kv coupled with ratings to 200A which provides a wide range of circuit protection. Their time-current characteristics allow for easier coordination with downstream devices.
2.75kV to 38kV
10 to 450A
Bussmann’s E-Rated Medium Voltage Fuses are defined by their melting time-current characteristic that permits their electrical interchangeability with other fuses of the same E Rating. Bussmann’s E-Rated fuses are available in ferrule, bolt-on and clip-lock and speciality mount fuses for Ampgard start motors.
Typical applications include medium transformer primary protection, medium feeder circuit protection, medium voltage switches, medium metal-enclosed switchgear and direct OE replacements.
Fast Acting Fuses
1 to 10kV, 1/16 to 10A
Bussmann’s Fast Acting Fuses vary in size depending on the electrical rating of the fuse to prevent over-fusing, offering a space saving size fuse. The fast acting fuses are typically used for medium voltage instrument protection and medium voltage circuit protection.
2.475kV to 38kV, 0.25 to 15A
Bussmann’s PT Medium Voltage Fuses are designed for potential and small power transformers. These general purpose, low amp, current-limiting E-Rated PT Fuses are defined by their melting time-current characteristics that permits their electrical interchangeability with other fuses of the same E Rating.
Typical applications include: medium voltage potential transformers, small medium voltage service transformers and small medium voltage control transformers.
R-Rated Circuit Protection Fuses
2.4kV, 4.8kV, 7.2kV, 25 to 450A
Bussmann’s R-Rated Fuses are designed for motor circuit protection; they feature easy installation in existing hardware. They are available in standard, ampgard hookeye and ampgard hookeye hermetically sealed and bolt-on styles to meet application needs.
Bussmann’s R-Rated Fuses are in a self-contained, non-venting package for installation indoors or outdoors in enclosure.
