Form of Internal Separation

CX panels are designed aroundthree different areas:

1. The busbar section locatedat the rear of the structurewhere the horizontal andvertical busbar are located.

2. The cabling section locatedin a separate fullysegregated cable chamberhousing both control andpower cable terminations.

3. The equipment section atthe front where thewithdrawable functionalunits are fitted.

IEC 61439-2 defines thevarious forms of internalseparation. The form of internalseparation determines howbusbars, functional units andterminals are separated fromeach other. CX is designed toprovide separation in both Form3b and 4b solutions.

Form 3b and 4b are defined as:the separation of the busbarsfrom each functional unit andthe separation of eachfunctional unit from each other.

The difference between Form3b and Form 4b is based onhow the terminals for outgoingconductors are separated fromeach other.

Form 3b solution is defined as:the separation of terminals forexternal conductors from thefunctional units, but not fromthose of other functional units,i.e. a common cable chamberwhere all outgoing terminalsare grouped together.

Form 4b solution is defined as:the separation of the terminalsfor external conductorsassociated with a functionalunit from those of any otherfunctional unit and the busbars.i.e individual separation of eachfunctional units outgoingterminals from each other.

Busbars (main + distribution) are separated from functional units

Functional units are separated from other functional units

Terminals are external to functional units

Terminations to functional units are separated from each other

Design philosophy of MCC Withdrawable units

The International Electro -technical Commission (IEC)developed short circuitperformance criteria forcontactors and motor starterscalled Type 1 and Type 2coordination. This standarddefines motor controllerprotection levels following ashort circuit fault.Performance,levels - eitherType 1 or Type 2 coordinationare determined by the level ofdamage to components withina motor controller after a shortcircuit fault on the outgoing

side of the controller. Thecombination of a motorcontroller (contactor or starter)and short circuit protectivedevice (manual motor protector,circuit breaker or fuse) mustmeet the following criteria asspecified by IEC 60947-4-1.

Motor controllers with Type 1coordination protection levelare allowed to have significantdamage after a short circuit andmay not be suitable for furtherservice without repair andreplacement of parts.

Type 2 coordination protectionprovides confidence that themotor control components willbe operable following a shortcircuit fault. This reusabilitytranslates into huge savingsdue to reduced downtime andreplacement costs.

CX motor control units aredesigned and tested to provideType 2 protection in the entiresystem thus ensuring thehighest uptime during itslifetime.

Type 2 Coordination

The withdrawable units in

CX are designed around

safety, ease of operation

using Eaton's patented

mechanical test posit ion,

ergonomic design and

flexibility. These units can

be easily exchanged

without having to

disconnect any power or

control cabling.

The following positions areavailable for each unit:

• Connected position

- Connected - ON

The unit is inserted, maindisconnect is closed, mainand control circuit isconnected.

- Connected - OFF

The unit is inserted, maindisconnect is open, mainand control circuits areconnected, padlocking ispossible.

• Test position

The unit is partially with -drawn and is separated 30 mm from the distributionbars, main disconnect isopen, main circuit isdisconnected, control circuitis connected, the test buttonis illuminated, padlocking ispossible.

• Disconnected position

The unit is partiallywithdrawn and is separated45 mm from the distributionbars, main disconnect isopen, main and controlcircuits are disconnected,padlocking is possible

• Removed unit

The unit is completelywithdrawn from the motorcontrol center and theoptional dummy unit can beinserted.

When the unit is in the "ON"position, the mechanical testposition mechanism isinterlocked with the operatingshaft of the main disconnectdevice (MCP) to ensure thatthe compartment can not bewithdrawn.

All positions are also clearlymarked on the drawer positionindicator strip with the blue(test) and green (disconnect)colours for extra visual aid.

The units are fully withdrawablewithout using tools and thedifferent positions of with -drawable parts (connected,test, isolated and removed) willbe achieved in accordance withtable 103 of IEC 61439-2.

The degree of protection in thetest and isolation position shallbe at least IP3X. This allowsthe operator to leave thecompartments in the panelwhen in the various positionswithout impacting the integrityof the complete system.

Main components for distribution and MCC

The low voltage system in yournetwork can be compared tothe engine and breaks in a car.If that is not reliable the cardoesn't function properly. In thesame way the componentsused in the switchgeardetermine the reliability of thesystem.

A system is only as strong asit's weakest link and so the

quality of the individualcomponents used determinesthe performance and quality ofthe system as a whole.

CX uses only the bestcomponents in the design ofthe structure and in thefunctional units. Eaton powerswitching and protectioncomponents are among thebest in the world.

Eaton delivers CX with Eaton'sAir Circuit Breaker (ACB) andMoulded Case Circuit Breaker(MCCB) functionality.

Understanding the interaction ofeach individual component andhow they operate within acomplete system is essential todelivering a fully type tested,reliable and efficient powerdistribution and motor control

All compartments of the CX aredesigned in such a way thatthe system is safe and easy tooperate. The use of anergonomical, smooth and smartdesign prevents operators inthe area of the switchgear tobe injured (from moving partsor parts that stick out of theunit) or by wrong operation.The front panel is included withall the important functions thatan operator needs for safe andefficient operation of a system.

Cable connection and userinterfaces for operation onthe same side of the system

To prevent mistakes in cabling,switching or other operations,the connection and interfacingwith the CX is always on thesame side on every panel.

Withdrawable units can beeasily exchanged withouthaving to disconnect anypower or control cabling

If the withdrawable units arefor the same function they caneasily be exchanged with eachother without major processinterruptions because of(dis)connecting any cables. Thiscapability potentially reducesthe inventory of spare with -drawable units for a system.

High Density stacking

For the withdrawable sectionsthe distribution busbars arerated at 1000 A and 2000 A up to 80 kA / 1 s allowing ahigh density of outgoing unitsto reduce the total footprint ofthe installations. Up to 25withdrawable units with 15 kWcan be populated per panel.

Compartments can bequickly and easily modified ifnecessary

Processes change and so doesthe need for motor control andpower distribution. The CX isdesigned to be flexible whenthe units need to be upgradedor modified. This can all bedone quickly and withminimum modifications tomaximize up-time for yourbusiness process. The cableconnection to drawout unitscan be carried out under liveconditions so there are nointerruptions.

Reliable system design

The use of high-grade materialsand components reducesmaintenance to a minimum.Due to the systematic use ofmaintenance free joints, factorytightened to optimum torques,inspections or retightening ofthe electrical main connectionsis not required. The CX has arobust design with a minimumnumber of parts. In addition,the complete platform iscertified to the highest degreeand every system is routinetested in our factories.

Sustainability

The quality of Eaton's

ideas, products and

solutions is visible by the

way they are designed

and produced.

That is how we definesustainability - an attitude thathas characterized our businessprinciple and determined theway we think for nearly 100years. Developing sustainablebusiness practices is not onlycritical to the future of ourcompany, but also for the

benefit of future generations.Sustainability includes not onlythe environment, but alsobroader issues like health andsafety of employees and localand global communities.Eaton's sustainability initiativesfocus on all these aspects andare leading Eaton to sustainablegrowth, both profitably andresponsibly.

Eaton is a pioneer in this regardwithin our industry sector. Theproduct plant of Eaton inHengelo (Netherlands) actsentirely in accordance with the

rules and procedures of theISO 14001 environmentalcertificate during thedevelopment and productionprocesses. Our solutions helpcustomers reduce their energycosts - and shrink the size oftheir carbon footprint - throughour portfolio of energy efficientproducts. The CX MCC isdesigned to have a reducedenvironmental footprint, besafe and less labor intensiveduring installation. This makesthe CX sustainable through itsentire life cycle.

Full Recycling or Reuse ofMaterials

CX has an expected lifetime ofat least 30 years. Depending onthe location where the systemis installed, the lifetime couldbe extended. At the end of lifeand at the time of decommis -sioning Eaton can be contactedfor the safe and efficientremoval of the CX. All materialsand components used in thesystem can be decommis -sioned, demounted and sortedfor either recycling or reuse.

Low End of Life (EOL) Disposal Cost

Life cycle assessment (alsoknown as LCA, Life CycleAnalysis and Eco-balance Study)is a scientific method used toquantify the environ mentalimpacts of a product or processfrom cradle to grave. As shownin Figure 1, Life CycleAssessment takes into accountthe product's full life cycle -from the extraction ofresources, production,consumption and recycling up tothe disposal of remaining waste.Because of the ability of a LCAto profile so many interrelatedfunctions and assess themcumulatively as well asindividually, it is possible toaccurately quantify impacts in allphases and across variousimpact categories.

As the focus on environmentalperformance intensifies,companies will be increasinglyexpected to demonstrateproven results for theirproducts. To understand andsubstantiate the environmentalbenefits of the CX product line,Eaton has been pro-active incommissioning a full life cycleassessment (LCA) study of theproduct. The detailed LCA studywhich has passed third party

critical review step is ISO 14044compliant. The results arepresented in Table 1.

The CX design and developmentteams have followed a LifeCycle Thinking approach whichseeks to identify possibleimprovements to goods andservices in the form of lowerenvironmental impacts andreduced use of resourcesacross all life cycle stages.

The key aim of Life CycleThinking is to avoid burdenshifting. This means avoidingshifting of impacts from onestage of the life cycle toanother; from one geographicregion to another; or from oneimpact category to another. Forexample, saving energy duringthe use phase of a product,while not increasing the amountof material needed to deliverthe savings.

Life Cycle Assessment

Process changes, for examplethe up rating of motor power orexchanging of compartments,may require on-site modifica -tion of motor starter circuitsand accordingly, enlargement or reconfiguration of compart -ments. The CX design is ableto meet these require mentsunder live conditions.

In cubicles with a verticaldistribution busbar system,screening plates provideisolation from live parts allowingfor the safe modification or

exchange of compartments. Thedistribution bars allow for theconnection of contacts along itsentire length thus allowing forthe modifica tion of outgoingcompartment sizes to be safelycarried out under live conditions.

Compartment separation platesare secured by two bolts at thefront of the cubicle. The separa -tion plates can be easily andquickly removed and secured ina different location to create anew compartment layout andsize.
