Effective September 2020Supersedes September 2018 **[BUSSMANN]** SERIES ## Technical Data 6002 ## PT Medium voltage fuses for potential and small power transformers ## **Features and benefits** - Low amp, current-limiting E-Rated PT medium voltage fuses are general purpose fuses defined by their melting time-current characteristic that permit their electrical interchangeability with other fuses of the same E Rating. - E-Rated general purpose fuses must have a current responsive element that will melt in 300 seconds at an RMS current within the range of 200% to 240% of the fuse’s nameplate current rating, fuse refill, or link per ANSI C37.46 for fuses rated 100E or less. - PT fuses are physically dimensioned for easy installation in existing hardware. - Space saving size eases design considerations for new installations. ## **Description:** Bussmann[TM] series indicating and nonindicating E-Rated, current-limiting, medium voltage fuses for potential, small power and control transformers. ## **Contents** **==> picture [194 x 187] intentionally omitted <==** **----- Start of picture text -----**<br> ||| |---|---| |Description|Page| |Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2| |2.475 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . .|3-6| |3.6 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . . . .|7-9| |5.5 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . .|10-26| |7.2 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . . .|27-29| |8.3 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . .|30-39| |12 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . . .|40-42| |15.5 kV fuses . . . . . . . . . . . . . . . . . . . . . . . .|43-52| |17.5 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . .|53-54| |24 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . . .|55-56| |25.5 kV fuses . . . . . . . . . . . . . . . . . . . . . . . .|57-60| |36 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . . .|61-62| |38 kV fuses . . . . . . . . . . . . . . . . . . . . . . . . . .|63-69| |Fuse mountings . . . . . . . . . . . . . . . . . . . . . .|70-71| **----- End of picture text -----**<br> - Current-limiting fuses provide positive interruption even on low fault currents. The fuse limits the magnitude of electromechanical stresses in the protected apparatus. - These fuses are in a self-contained, nonventing package for installation indoors or outdoors in an enclosure. - Available in indicating and non-indicating versions. - Open fuse indicator speeds troubleshooting by providing a positive visual indication of fuse operation. ## **Typical applications** - Primary protection of: - Medium voltage potential transformers - Small medium voltage service transformers - Small medium voltage control transformers.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 540,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
