® Bussmann Semiconductor Fuses FBP 700 Volts AC/DC, 35-1000 Amps 2 Ultra High Degree of Current Limitation and Low I t. • The heat energy of even low-level fault currents can quickly destroy a semiconductor device. * Buss FW type fuse limits peak let-thru current to a level which is a fraction of the potential available short-circuit peak current. • Fast speed-of-response to build-up of short-circuit current and the quickly decaying short-circuit current as the fuse 2 suppresses internal arcing together can limit the I t let-thru to 2 values substantially lower than the I t withstand of the semi- conductor device. Current Rating. • Current rating is given in AC (rms) for an ambient tempera- ture of 20ºC (68ºF). • Although these fuses can be operated at 100% of rating, good design practice dictates some derating (i.e. for ambient temperature), typically this is 20%. Voltage Rating. • Rated voltage of Semiconductor fuses is given in terms of A.C. operation, 60Hz. • When used in D.C. circuits no voltage derating is required provided the minimum interrupting capability is eight times the fuse rating and the time constant does not exceed those specified in U.L. 198L. CATALOG SYMBOL: FBP 2 Total Clearing I t. 700V AC, 700V DC 2 • Maximum values of total clearing I t are obtained at the rated INTERRUPTING RATING 200,000 AMPERES A.C. voltage, an arcing angle between 60º and 90º, at an RMS SYMMETRICAL available symmetrical rms current of 100,000 amperes, and U.L. RECOGNIZED at a power factor of less than 15%. (GUIDE #JFHR2, FILE # E56412) Arc Voltage. • The arc voltage which develops across a fuse when it is clearing a fault current must always exceed the system volt- Catalog Numbers age. FBP-35 FBP-80 FBP-350 • This arc voltage may reach a value which is twice that of the FBP-40 FBP-90 FBP-400 system applied voltage.

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
