Maximise the Uptime of your distribution system
Energy Monitoring
Monitoring the energyconsumption is one of the keyelements for asset manage -ment. Eaton technologysupports this task and canprovide integrated visualisationand logging within xEnergyMain® switchgear. Data iscollected from devices like AirCircuit Breakers, Moulded CaseCircuit Breakers and FusedCombination Switches anddisplayed on a panel mountedHMI. The operating data fromthe connected devices iscommunicated via ModbusRTU or other communicationplatforms.
The information can beobtained onsite on an EatonHMI or remotely whenconnected to your network orcontrol system.
Energy montoring and controlincreases the uptimecapabilities of the powerdistribution system by not onlylogging and displaying energyconsumption but also byproviding predictivemaintenance information toreduce unexpected outages.Providing prewarnings ofoverload before breakers willtrip so that preventive
maintenance can be performedbefore failure. With the newNZM Moulded Case CircuitBreakers the unique featureBreakerHealth provides up-to-date status of thelongevity of the installed base.BreakerHealth provides ContactWear Information and isregistering mechanical andelectrical operations providinglifespan information andwarning messages when thelifespan is low to supportmaintenance and budgetrequirements for replacementof breakers.
Eaton’s SmartWire-DTcommunication system is usedin xEnergy Main® to recordinformation from motorstarters, soft starters andvariable frequency drives. The retrieved information istransferred via standard fieldbusprotocols to the higher-levelPLC. Thanks to the use of
intelligent SmartWire-DTswitchgear, this not onlyconsists of digital signals forswitching or monitoring ofpositions or overloadinformation but also analoguevalues such as the actualcurrent or the condition of a trip unit can be determined and evaluated.
SmartWire-DT - Connectivity
Multiple critical businessservices are running withinbuildings, data centers orindustrial premises. Theseservices are vulnerable topower problems, both in termsof power availability and quality.To secure maximum uptime
xEnergy Main® is offering awide range of solutions:
Multiple interlockingpossibilities

Form of Internal Separation
xEnergy Main® panels aredesigned around three differentareas:
1. The main busbar anddistribution busbar sectionsegregated from theequipment section.
2. The cabling section located in a separate fully segre gatedcable chamber for feedingcables to the functionalsections and/or housingcontrol and power cableterminations, depending onthe form of separation.
3. The equipment section at the front where thefunctional units are fitted.
IEC 61439-2 defines the variousforms of internal separation.The form of internal separationdetermines how busbars,functional units and terminalsare separated from each other.xEnergy Main® is designed toprovide separation in Form 2b,3b, 4a and 4b solutions.
Form 3b, 4a and 4b are definedas: the separation of thebusbars from each functionalunit and the separation of eachfunctional unit from each other.
The difference between Form4a and Form 3b/4b is theposition of the terminals to thefunctional units. In a Form 4a
solution these terminals arelocated in the same compart -ment as the functional unit.
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. Internalseparation in accordance withIEC 61439-2.
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.
* BS-EN 61439 Compliance for Form 4a type 2 and Form 4b type 6 and 7. Form 4b type 6 is available as "compartmentalised" or "group-mounted".

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
Either Type 1 or Type 2coordination are determined bythe level of damage tocomponents within a motor
controller after a short circuitfault on the outgoing side of thecontroller. The combination of amotor controller (contactor orstarter) and short circuitprotective device (manual motorprotector, circuit breaker or fuse)must meet the following criteriaas specified 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.
xEnergy Main® motor controlunits are designed and testedto provide Type 2 protection in the entire system thusensuring the highest uptimeduring its lifetime.
