Why a guide to practice?There is a precise conformity on the content of the Standard 61439in the IEC and EN world of standards. Consequently this documentuses the writing IEC 61439 / EN 61439 in the following.IEC 61439 / EN 61439 New tasks and responsibilities for the electricianIEC 61439 / EN 61439 shows how a low-voltage switchgearassembly, which is safe for the user, can be built. In addition tochanges affecting the design of an assembly, the manufacturer of aswitchgear assembly is faced with new tasks and responsibilities.Guide 61439 for the practice:5 steps to a standard-conforming switchgear assemblyThe guide lists the process of design, assembly and documentationof a low-voltage switchgear assembly in the order of the necessarysteps and at the same time assigns to these steps the relevantsections from the standard IEC 61439 / EN 61439.The application of the guide is focused on the manufacturingof distribution boards up to 630 A and in addition to checklistsand instructions regarding the verification of compliance with themaximum temperature rise.Defines which documents belong to a low-voltage switchgearassembly and which verifications need to be maintained. Makesstatements regarding the rating of the assembly so that a designverification can be maintained.The guide can be downloaded from:wwww.hensel-electric.de/61439Step 1Collecting all the project dataStep 2Assembly design and design verificationStep 3Assembly / manufacture of the distribution boardStep 4Manufacturer's markingStep 5Declaration of CE conformity (check lists)HENSEL, as the system manufacturer, supports panel builders with this guideto design and assemble safe low-voltage switchgear assemblies according toIEC 61439 / EN 61439.4
Basics of IEC 61439 / EN 61439Legal Basis of LVD 2014/35/EU*In the European Union, theLow Voltage Directive LVD2014/35/EU forms the legalbasis for all electrical equipmentbetween 50 and 1000 V a.c., or75 and 1500 V d.c.EU onlyCompliance with this legal basis is confirmed by the declarationof conformity by the manufacturer of a switchgear assembly.Reference to EN 61439 implies that the basic requirements of thedirective have been met. If the legal requirements are not met, thepurchaser has no liability protection!If harmonized standards are not applied, the manufacturer of theswitchgear assembly has a duty to establish compliance with theabove protection objectives by appropriate means.This directive pursues the protection objective that electricalequipment must not jeopardizethe safety of persons, livestock,and the preservation of property,and refers to the harmonizedstandards, which are publishedin the Official Journal of the EU.*LVD Low Voltage DirectiveStructure of IEC 61439 / EN 61439IEC/TR 61439-0Planning guide for low-voltage switchgear assembliesIEC 61439-1 / EN 61439-1General requirements for low-voltage switchgear assembliesIEC 61439-2 / EN 61439-2IEC 61439-3 / EN 61439-3IEC 61439-4 / EN 61439-4Power switchgear andcontrolgear assembly (PSC)Distribution boards intended tobe operated by ordinary persons(DBO)ConstructionConstrConstructuctionion sisitete disdistridistributorstributbutorsorsIEC 61439-5 / EN 61439-5IEC 61439-6 / EN 61439-6IEC/TS 61439-7CableCable DisDistriDistributiontributbutionion CaCabinCabinetsbinetsetsBusbarBusbar ibutorDistributoror for cacampicamping,mping,ng, mamarkemarketrkettplaces, marinas and chargingstations for electric vehiclesIEC 61439-1 / EN 61439-1is a general part which mustbe read in conjunction withthe product sectionIEC 61439-2 to -7 /EN 61439 -2 to -7.Does not include productspecific requirements.Describes operating conditions,assembly requirements,technical properties andrequirements, as well asverification options for lowvoltage switchgear assembliesand lists the terms used.New terminology of product responsibility:Original manufacturer (system manufacturer) and manufacturerof switchgear assembly (panel builder) with new regulation forproduct responsibility.More safety through the definition of requirementsfor switchgear assemblies that affect the construction of thesystem, e.g. rated short-time withstand current, current carryingcapacity, resistance to temperature rise.More safety by determining the rating datathat are essential for the function of a switchgear assemblyunder operating conditions. For this purpose, the switchgear isconsidered as a BLACK BOX.5
Basics of IEC 61439 / EN 61439Manufacturer's product responsibilityThe manufacturer is primarily responsible for compliance with the law and the safety of a distribution board! He must provide evidence thatthe distributor was free of design, manufacturing and instruction errors when brought on the market.Thereby he must prove the safety of the assembly according to the appropriate documents (risk analysis and assessment).These documents must be retained. He must create a declaration of conformity and affix the CE marking visibly.EU onlyWho is the manufacturer of a switchgear assembly?The new standard clearly regulates the responsibility for a distribution board placed on the market. It distinguishes between the originalmanufacturer (system manufacturer) and the manufacturer of the switchgear assembly (panel builder).Panel builderPanel builderPanel builderSystem manufacturer, e.g. HENSELOriginal manufacturer (system manufacturer)Manufacturer of the switchgear assembly(Panel Builder)Responsible for:Responsible for: the thedistribution board system theverification of the design by testing, calculationor construction rules thedocumentation of this design verification,e.g. test documentation, derivations, calculationscreation of tools to design and appropriate instructions forassembling and testingrating of the switchgear assembly according to thecustomer/operator requirements thecompliance with the design verification of the originalmanufacturerthe declaration of conformity to the customer(Declaration of Conformity) theThe original manufacturer (system manufacturer) alreadyprovides the respective verifications for its distribution boardsystem.6EU only themarking and documentation of the assembly theperformance of the design verification and documentationPanel builders who have no distribution board system of theirown and assemble verified systems into ready-to-connectswitchgear assemblies thus decide for themselves about theirown verification efforts, as they can use the documents of theoriginal system manufacturer.

Step 1:Collecting all the project dataThe user specifies the operational requirements and conditions for alow-voltage switchgear assembly.Where special operating conditions exist that are not covered by thestandard, in addition also the applicable special requirements haveto be met or special agreements between the manufacturer of theswitchgear assembly and the user must be made. The user mustinform the manufacturer if such extraordinary conditions exist.The correct rating of the key interfaces in the switchgear assemblyis crucial for its function under operating conditions. For thispurpose, the switchgear assembly is considered a »BLACK-BOX«with four interfaces for which the manufacturer of the switchgearassembly must define the correct design values when designing theassembly.The design of the switchgear assembly is dependent on theconditions and data such as:1.1 Installation and ambient conditions1.2 Operation and maintenance1.3 Connection to the public power supply system1.4 Electrical circuits and consumersInterface characteristics of assembliesSwitchgear assembly as BLACK BOX with the 4 interfaces according to IEC 61439 / EN 614391.1Conditions at place ofinstallation/environment1.2 Operation and maintenance- Installation site- Special requirements foruse in commercial andindustrial applications- Access and operation only byskilled persons (electricians)- (Device) operation by ordinarypersons - unskilled personsBLACK BOXENYSTARCombinable enclosuresystem, insulationenclosed, totallyinsulated, IP 66,for the assembly ofdistribution boardsup to 250 A intended tobe operated by ordinarypersons (DBO) accordingto IEC/EN 61439-3Mi DistributorCombinable enclosuresystem, insulationenclosed, totallyinsulated, IP 65,for the assembly ofpower switchgear andcontrolgear assemblies(PSC) to 630 Ain accordance withIEC/EN 61439-21.3Connection to the publicpower supply system1.4Electrical circuits and consumers- Nominal data of the feed- Nominal values transformer- Short-time withstandcurrent- Determination of the thermalpower dissipation8- Rating of outgoing circuits- Determination of the rated diversityfactor (RDF)
