KearneyTM fuse links

General
Eaton's Cooper PowerTM series KearneyTM fuse links can be applied to a variety of applications requiring overcurrent protection of distribution systems and equipment. When properly coordinated with other overcurrent protective devices, sectionalizing to isolate faulted feeder branches or equipment can be accomplished.
Kearney fuse links are available in a variety of types offering a wide selection of operating characteristics. The links incorporate low melting temperature elements, captive washers, highresistance strain wires, and color-coded high strength tubes. The low temperature melting tin elements enhance overload capability by guaranteeing non-damageability of the fuse tubes. These elements are capable of absorbing vibration as well as thermal shock due to current surges and heating and cooling throughout the daily load cycle. They can be further distinguished by their

years of superior service proven by Time Current Characteristic (TCC) Curve verification of aged fuse links. Consult your Eaton representative for more details.
The fuse links have been designed and tested to the IEEE Std C37.42TM standard.
The following are the types of fuse links offered:
� Type K
� Type T
� Type 200TM (N)
� Type KS
� Type SQ
� Type QATM
� Type X
� Secondary Indicating Fuses

Kearney fuse links

Internal construction
All Kearney fuse links are designed with low melting temperature element components of either tin or solder filled dual element construction. Each element material shipment from our supplier is accompanied with a certification of quality and composition. The diameter is verified in incoming inspection. Low melting temperature fuse links Types K, T, 200, X and KS have exceptional overload capability. They are designed to carry 150% of their continuous current rating continuously without damage to the fuse link itself or to the cutout fuseholder in which they are installed. (Care should be exercised so that the current rating of the cutout is not exceeded.)
Tin element
Links using pure tin elements have a precision gauged strain wire crimped in parallel to provide tension loading properties. The tin element is soldered into position providing the industry's best possible electrical connection between the element and its terminals. The low melting temperature of the tin allows all of the fuse link components to operate at a lower temperature while providing long term reliable TCC.

REMOVABLE BUTTONS Allow fuse links to be used in all open and enclosed cutouts, including cutouts with arcshortening rods.
CAPTIVE WASHER Will not fall off prior to or during installation. (Can be removed for use where 1/2" button or no button is required.)

AMPERE SIZE Marked on top of screw terminal, so that it can be seen after the fuse link is installed in a fuseholder.
IDENTIFICATION Fuse link type, ampere size and date of manufacture marked on periphery of screw terminal.
SWAGED FERRULE Extends around fuse link tube to ensure single end expulsion on low fault currents.

Dual element
There are two dual element designs. The dual element design for 1 and 2 A K, KS, X, T, 200 (N), QA, and SQ 0.2 A - 1.45 A link assemblies is composed of a heater coil mounted around a solder pot that is soldered to a fuse element. Types KS and X links above 2 A and SQ links above 1.4 A have two wire elements in series which are axially inserted into a soldered coil.
Dual element links which use solder coils are mechanically crimped to the body and screw terminals. The elements are inserted into the coil and meticulously gauged to assure that active element lengths are maintained. The soldering process then permanently sets the active elements to the proper TCC curve and guarantees positive electrical continuity.
Dual elements allow the fuse to respond as low temperature single element fuses for long time overloads, yet have superior lightning surge withstand capability. Both types of links have up to 26 times more surge withstand capability than single element fuse links.

FUSE LINK TYPE Marked on length of tube to aid in identification of fuse type.

COLOR CODE High bust strength tube color coded for each fuse link to minimize the potential of installing wrong fuse link type.
SPRING On all fuse links through 25 A to aid in clearance of low level faults by ejecting the fuse cable and creating a positive element separation.

Final construction
After passing in-process QA checks, high strength color coded tubes are swaged to both the single and dual element fuse links. A unique self locking washer and button is attached to the screw terminal. Every fuse link is axial pull tested to verify mechanical strength before packaging in the Kearney unique "lineman friendly" pull-tab fuse packs.

Fuse link selection
Type K (tube color brown)
Kearney Type K fuse links have been tested to the IEEE Std C37.42TM standard requirements for a "fast" fuse. The nominal speed ratio of Type K fuse links is 7. Type K fuse links are well suited where "fast" time-current characteristics are desired such as for capacitor protection.
Type 200 (N) (tube color green)
Kearney Type 200 fuse links are classified as "medium" speed fuses, with a nominal speed ratio of 10. Type 200 fuse links provide more surge withstand capability than Type K links, and provide good coordination possibilities with relays and reclosers.

Figure 1. Fuse link features.
Type QA (tube color yellow) Kearney Type QA fuse links are classified as "medium" speed fuse links with a nominal speed ratio of 10. Type QA fuse links will carry 100% of the rated current continuously without damage, and provide good coordination possibilities with relays and reclosers.

Type T (tube color white)
1000
Kearney Type T fuse links have been tested to the IEEE Std C37.42TM standard requirements for a "slow" fuse link. The nominal speed ratio of Type T fuse links is 12. Type T fuse links provide slower timecurrent characteristics than Types K, 200, and QA, and coordinate well with relays and reclosers.

Type KS (tube color light-blue)

100

1 Minute

Kearney Type KS fuse links employ dual element construction which

gives the Type KS high surge withstand capability, and a nominal

speed ratio of 20. Classified as "very slow" fuse links, the Type KS

has greater surge current withstand capability than the Type T, and is

a good choice for line fusing and transformer protection.

Time in Seconds

Type X (tube color orange) and Type SQ (tube color brown)

Kearney Type X and SQ fuse links are specially designed for trans-

former protection. Type X and SQ fuse links employ dual element

construction, which allows the time- current characteristic to be care-

fully shaped to closely match the IEEE Std C57.91TM standard loading

curve for transformers while providing excellent surge withstand

to avoid nuisance blowing from lightning and switching surges. The

nominal speed ratio of the Type X and SQ fuse links is 32.

Current in Amperes: x 1 at 25 kV.

Packaging
All fuse links are packed in individual cartons for the maximum protection and ease of use. Cartons are perforated for easy opening. Fuse links can be removed with gloves on. Fuse Link Type and Ampere Ratings are clearly marked on the carton. The print will not smear or run.
Five Pack Sleeves: Fuse Link Type and Ampere Rating are clearly marked on box front and end of cartons. Individual cartons are tabbed so that remaining fuses stay securely in the carton as others are removed.
Overcartons: All fuse links 100 A and below are packed in protective overcartons 25 per box. Catalog Number, Fuse Link Type, Ampere Rating, and Date of Manufacture are marked on the label for ease of selection.
Note: SQ links are individually packaged in transparent plastic bags. Bagged fuses are packed in an overcarton for protection and ease of handling. The catalog number, fuse type and amp rating are clearly marked on each bag and on all cartons.
Comparative melting speed ratio chart
Electrical equipment such as transformers, switches, relays, and conductors are exposed to various levels of current during normal operation. Generally, electrical devices can withstand high currents for a short period of time and low current for longer periods of time without thermal or mechanical damage. The ability to withstand various levels of current for various periods of time is referred to as time-current characteristics.
Coordination of power systems involves the selection of fuse links to protect equipment with various time-current characteristics while coordinating with reclosers, circuit breakers, sectionalizers, relays, and other fuses. Kearney offers six types of fuse links with a wide range of time-current characteristics (refer to Table 1).
The speed ratio of all fuse link sizes 100 A and below is the ratio between the current that melts the fuse in 0.1 seconds to the current that melts the fuse in 300 seconds. The higher the ratio, the slower the speed of melting. For fuses rated above 100 A, the speed ratio is between the melting currents at 0.1 second and 600 seconds.

Indicating type tubular secondary fuses
Indicating type tubular secondary fuses protect transformers and capacitors from secondary overloads and faults. Each secondary fuse has a spring locked red plastic flag which springs out from the cartridge when the fuse link melts, indicating an outage. Fuses are available with insulated or non-insulated leads.

Universal adapter assemblies
This universal adapter assembly will adapt Fit-AllTM fuse links for use in the cutouts that have bolt-type cable connections to connect the upper as well as the lower cable. Note from the table that only five sizes are required to adapt to any type fuse.
