This retrofitting kit is designed for replacing the KP-800 800A, KP-1600 1600A, or KP-2000 2000A air circuit breaker
in the KP-line switchgear. It allows an Emax 2 withdrawable air circuit breaker of the same size as indicated in Table
A to be attached to the original switchgear cradle assembly and racked into the switchgear enclosure.
IMPORTANT !
Retrofitting allows an obsolete control and protection device to be replaced, but does not allow the ratings of the
original switchboard to be altered in any way.
The retrofitting kits are dimensioned and validated for the obsolete device performances which may be lower than the
new Emax 2 ratings.
Consult ABB for further details.
Full correspondence of the electrical characteristics is guaranteed (rated current excluding derating if indicated in the
table, and breaking capacity) so long as the kit is chosen in accordance with the indications in the ABB technical
catalogues dedicated to retrofitting products. The kit has been designed also to preserve the insertion/extraction
operations functionality and the optional auxiliary (secondary) circuits of the obsolete circuit breaker. The CiC is
installed and then locked on the switchgear cradle, thus making use of the of its plug-in features as established in the
operation and maintenance manual of the new Emax 2 circuit breaker without having to modify any of the live parts
of the switchgear.
ATTENTION !
The instructions concern the sole assembly of the retrofitting kit. They do not substitute for the instruction in the
installation, operation, and maintenance manual of the Emax 2 circuit breaker installation instructions document
number, 1SDH001000R0002.
If optional auxiliary (secondary) circuits are required, refer to section 12.
Structure Details
The fixed part of the new Emax 2 is mounted to a steel sheet structure (CiC) that is then mounted into the KP-line
switchgear cell. The Emax 2 cradle is fitted with custom silver flashed copper run backs and finger clusters that align
to and mate with the existing KP-line switchgear power circuit stabs. The entire assembly mounts on the original K-
line cell rails. No additional phase barriers were required for this CiC. The weight of the low voltage cradle-in-cradle
assembly is listed in table B.
