Interchangeability
EC INSULATORS design a cutout that could interchange fuse-holders and mounting assemblies with those of another manufacture. Standard Type C fuseholders and mounting assemblies are mutually interchangeable with S&C Type XS and ABB Type ICX cutouts. (within the same voltage class).
Application
The Type C-Polymer Loadbreak Cutout is available for ap-plication on 15 and 27kV distribution systems. The addi-tion of the arc chute expands the flexibility of the protective devices family by providing loadbreak capability for cutouts and disconnect solid blade units. The loadbreak cutout provides short circuit protection to utility lines with the added feature of a loadbreaking function.
The loadbreak cutout is applicable for transformer and capacitor bank switching or line sectionalizing. Loadbreak cutouts provide protection from overloads that just melt the fuselink through the maximum interrupt capacity of the fuseholder. They also provide loadbreak capability through 300 amperes.
Design
All design features and most components of the load-break unit are identical to those incorporated in the Type C-Polymer standard cutout. The loadbreak portion of the Type C-Polymer Loadbreak cutout is a heavy duty, reliable load interrupter that provides a positive visible loadbreak. A common loadbreak mounting assembly will accept the Chance Type C-Polymer 100 amp and 200 amp loadbreak fuseholders or a 300 amp loadbreak disconnect blade. The Type C-Polymer LOADBREAK fuseholder is not designed to be interchangeable with any other manufacturer’s cutout.
Ratings/Specifications
15kV Type C-Polymer loadbreak cutout has a maximum design voltage rating of 15kV. There are no voltage restric-tions on applicaton to grounded wye, ungrounded wye, or delta systems having maximum operating voltages (line to line) equal to or less than the cutout maximum design voltage rating.
Advantages & Features
The total installed cost of a ECI cutout-arrester com-bination is less than the total installed cost of separately purchased components. The combination units install faster, more economically and take up less space in storage, transit and service. Each combined unit takes up a minimum of space on the crossarm and has a favorable weight distri-bution for minimal off-center loading. The field-proven quality of both cutout and arrester assure consistent high performance for the combinations.
