IntroductionThe CR7160 Limitamp® Controller, a quality GE product,was designed and manufactured to give long and satisfactoryservice. This bulletin contains items that, through normal use,may require periodic replacement; other items may neverneed service or replacement during the useful life of theequipment.

High-Voltage Contactor NameplateHigh-voltage contactor renewal parts are found in separaterenewal parts publications depending on the contactor cata-log number. This catalog number is found on the contactornameplate mounted on the steel bracket directly above thecontactor coil. An example of this nameplate is shown below:

Limitamp Panel Data NameplateThis nameplate is mounted near the starter handle operatoron the high-voltage door. It contains all the necessary infor-mation for the factory to positively identify the starter and itsbill of material. This information must accompany all partorders and quotation requests. An example of this nameplateis shown below:

Catalog Numbering SystemLimitamp control is manufactured in three constructiontypes: one-high, two-high and three-high. One-high construc-tion consists of one medium-voltage contactor in one 90-inch-high enclosure. Two-high construction contains two medium-voltage contactors in one 90-inch-high enclosure. Three-highconstruction has three medium-voltage contactors in one 90-inch-high enclosure.

You should first determine the construction type (one-high,two-high or three-high) of your equipment. After determina-tion, the following pages should be consulted:

Pages 4 and 5 for one-high constructionPages 6 and 7 for two-high constructionPages 8 and 9 for three-high construction

Another method of identifying construction is through thecontroller “CR” number (shown on the panel data name-plate) . Example: Catalog Number 7160A118G. The alphasuffix determines one-high, tiuo-high or three-high; G is one-high,K is two-high and H is three-high. Vacuum starters are designatedby an M suffix. Example: Catalog Number 7160A118GM .

Figure 2. Limitamp Panel Data Nameplate

The required information is the catalog number and thediagram number. The catalog number from the sample aboveis 0607X0431V02 A01. The number can be broken down asfollows: 0607X0431 is the material list number or shop ordernumber for the job, V02 is the overall lineup designation, andA01 is a section in that lineup. The diagram number identifiesthe group of drawings that pertain to this particular projectorder.

Sections that do not have a panel data nameplate will have acompartment nameplate mounted on the right side doorflange. An example is shown below:

Figure 3.LimitampCompartmentNameplate

This will provide the catalog number only. The diagramnumber can be obtained from any Panel Data Nameplate onthat lineup.

Handle Assembly Some parts of the handle assembly are replaceable and can beidentified by part number as shown below:

V

The non-load break isolating mechanism (handle assembly) isa complex construction requiring a special bench fixture toassemble and adjust the mechanical interlocking mechanisms.Therefore, we recommend the entire assembly be replaced ifthe handle mechanism becomes extensively damaged.

Limitamp® Medium voltage Motor Control

A one-high vertical bus assembly consists primarily of the busbars, shutter, and operator assembly all constructed as oneitem. The complete assembly is the easiest to replace; howev-er, if the user has the expertise, the bare bus bar assembly canbe installed in the field. The following table is a cross refer-ence from the complete assembly group number,

.194A4480G*, to the bare bus bar assembly, 116C992_G_,shown in the following table.

CPT Fuse Support Assemblies Intermediate Stab and Track Assembly116C9939AAG2 and G3

CPT primary fuse support assemblies are most easily identi-fied by using the fuse catalog number, type of enclosure (one-high, two-high, three-high) and the matrix below. This willprovide the complete fuse support assembly catalog number.

Track assemblies are used in two- and three-high enclosures tosupport the contactor. This assembly includes the intermedi-ate stabs.
