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.
