® Bussmann Cable Limiters K Series 600 Volt Copper Limiters General Information: • Selection: unlike fuses, the current-carrying capacity of cable limiters is denoted by cable size rather than amperage. • For example, a “4/0” limiter will carry the current of a 4/0 cable. • Buss Cable Limiters help protect cables against short- circuit currents. • Increase system reliability. • Cable limiters installed at each end of each cable are an excellent method to maximize continuity of service when there are three or more cables per phase. If one cable has a fault, that cable’s limiters open and the other cables’ limiters continue carrying current. Cable limiters are often used in utility low voltage networks and large multi-cable per phase service entrances. • Under high short-circuit conditions, they can cut off fault currents within one-half cycle (0.008 seconds). • This fast action reduces insulation damage from the immense heat that is developed by sustained fault current flow (often 30,000, 50,000, 70,000, 150,000A magnitude). • Reduces the high build-up of mechanical forces due to intense magnetic fields. • Cable limiters help confine damage to the point of the short-circuit. Help stop long-length cable burn-back and striking of multiple arcs. • Apart from the loss of power and operational shutdown, short-circuits can do devastating damage to conductors. • The cost of total replacement of cables, particularly when they are buried underground, outweighs the nominal cost of cable limiter protection. • Without the protection of limiters, under short-circuit condi- tions, a cable may continue to arc at several points and cause severe damage to other components of the sys- Catalog Symbol: K Series tem…it does not necessarily burn clear. Cable Limiters Interrupting Rating: 200,000A, RMS Sym. • Buss Cable Limiters are short-circuit devices (unresponsive Voltage Rating: 600Vac to light cable overloads) with several types of terminal con- nections to permit easy mechanical connection to a broad range of cable sizes. • Totally self-contained, static device. • Unlike the open link-type limiters, there is no venting of ionized gases or explosive action. • Has stable, unchanging characteristics. • High interrupting rating. • KDM, KDR, KDP and KFM copper cable limiters are UL list- ed under File E990818. For use at 600Vac on faults up to 200,000A.

What they say about us
FANTASTIC RESOURCE
One of our top priorities is maintaining our business with precision, and we are constantly looking for affiliates that can help us achieve our goal. With the aid of GID Industrial, our obsolete product management has never been more efficient. They have been a great resource to our company, and have quickly become a go-to supplier on our list!
Bucher Emhart Glass
EXCELLENT SERVICE
With our strict fundamentals and high expectations, we were surprised when we came across GID Industrial and their competitive pricing. When we approached them with our issue, they were incredibly confident in being able to provide us with a seamless solution at the best price for us. GID Industrial quickly understood our needs and provided us with excellent service, as well as fully tested product to ensure what we received would be the right fit for our company.

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.
