ABB PMAX IEC COPPERwww.SBB.comSTANDARDSINTRODUCTIONPMAX H is a patented range of busbar trunking that is utilised withinbuilding and industrial applications to deliver power to electrical loads.It is an alternative to traditional cabling and provides numerousadvantages to the Installer and Client including savings on space, time and cost.StandardsThe PMAX range is fully ASTA Tested Certified and is CE approved. It is manufactured in a certifiedmanagement system environment where Quality BS EN ISO 9001:2008, Safety OHSAS 18001:2007and Environmental IS0 140001 standards are applied to all aspects of the manufacturing andinstallation processes. It is manufactured in accordance with IEC61439-1 and IEC61439-6.There are also electrical savings due to reduced losses, reduced voltage drop andflexibility to reposition load centres using tap-off points.Type Tests10.2 Verification of Strength of materials and parts10.3Verification of Degree of protection of enclosures10.4Verification of Clearance and Creepage distances10.5Verification of Protection against electric shock and integrity of protective circuits.10.9Verification of Dielectric properties10.10 Verification of Temperature rise limits10.11 Verification of Short-circuit withstand strengthThe PMAX range of products is built with patented processes that make it the most reliableproduct of its type, providing peace of mind for your installation.

Site surveys 3D - CAD Drawings Project Management Thermal ImagingOur highly skilled team are experts at providing the client with exactly what they require and areexperienced in producing bespoke parts to meet the client’s unique demand.Seismic ComplianceThe product has a qualification level - high in accordance to IEEE standard 693-2005.All certificates available on requestThe ABB PMAX (H) IEC Copper range is a 1000 Volt, totally encased, non-ventilated, lowimpedance sandwich construction, with epoxy resin coated copper conductors. The range isavailable from 1100A to 6600A available with multiple bar configurations to suit projectrequirements, including Neutral, Double Neutral, Earth and Half Earth.The bar is housed in an Aluminium casing which also acts as an Integral Earth and is available with achoice of ingress Protection Ratings from IP55 to IP67. The busbar is painted in grey (RAL 7035).Other colours can be accommodated on request.OHSAS 18001:2007OHS 533652ISO 9001:2008FM 12680ISO 14001:2004No: EMS 566536FEATURES Copper conductor’s mill, tin or silver coated-finish. Joint Pack construction with double headed shear nuts, for quick installation. Up to five tap off points per three metre length. All tap offs have mechanical/electrical interlocks with an “earth first, break last” safety feature. Pressed out tags for tap off connections – this is a patented process.0102
ABB PMAX IEC COPPERTECHNICAL FEATURESConductor/Insulation SystemPMAX H is constructed from high density 99.99% conductivity copper. The conductors areinsulated with a Class B or Class F epoxy insulation applied uniformly by our automated electrostaticcoating process. The epoxy coating is non-hygroscopic, chemical resistant, and has outstanding heattransfer characteristics making it ideal for sandwich construction applications. Epoxy has excellentdielectric strength, is flame retardant and is impact resistant. The Copper is also available with theoption of tin or silver plating.The Low Impedance Sandwich Design: Improves heat dissipation. Improves short circuit rating. Reduces voltage drop/ impedance compared to cable. Removes potential pathways for the propagation of flame, smoke and gas through thebusbar system.TECHNICAL FEATURESPhase P100%0%TP/N100%100%CaseTP/E100%0%100% or 50%TP/NE100%100%100% or 50%TP/DN100%200%CaseNote: Case, refers to the Aluminium casing been utilised as a 100% housing ground.Fire Barrier SystemABB offer a fully certified fire wall penetration barrier. This fire barrier can be supplied witheither a four hour or two hour rating.Key considerations for utilizing fire barriers:1. Life safety2. Prevention of the passage of smoke or flames from one enclosed space to another.If a fire barrier is not used then the busbar will simply melt when under fire load leaving a void in thewall allowing the passage of flames and smoke from one area to another.PMAX Fire BarrierEpoxy Coated Copper ConductorsThe distribution busbar lengths have tabs pressed into the conductor to allow tap off units tobe connected. This patented method for creating the tabs does not require any welding process,meaning the integrity of the conductor is not compromised.Housing DetailsThe PMAX H range is constructed with an all-aluminium housing. Aluminium offers numerousadvantages when compared to our competitors steel housings. Aluminium is a very light metal with a specific weight of 2.72 g/cm3, about a third that of steel(7.85g/cm3). This reduces transportation costs and makes the product much easier to install. Aluminium is non-magnetic and has a significant reduction in reactance when compares to steel. Unlike steel which rusts, Aluminium naturally generates a protective oxide coating which makes ithighly corrosion resistant. This means the product is more durable and requires less maintenance. Aluminium is an excellent heat and electricity conductor and in relation to its weight is almosttwice as good a conductor as copper. This means that the housing can be used as an earth along thelength of the busbar.Isolated Earth Bar (50% or 100% Copper)ABB offer a 50% or 100% fully isolated earth for systems where earth isolation is required suchas systems with heavy microprocessor, based loads, or large computer based installations. Thecontinuity is maintained through the joint pack.Fire BarrierDouble Neutral (200% Option)ABB offer a fully rated 200% neutral option for busbar systems with non-linear loads.The additional neutral capacity prevents overloading caused by zero sequence harmonic currents.0304
ABB PMAX IEC COPPERSTRAIGHT LENGTHSELBOWSStraight LengthFeeder lengths account for the bulk of a busbarrun. Distribution lengths are like feeder lengthsbut with tap off slots.yyTap off slots allow tap off units to be pluggedinto the busbar run. The tap off slot outlet andcover are made from a durable, high strength,Class B, 130 C insulation material.yThe tap off slot cover is designed to preventaccess to the contacts behind the cover andprevent the entry of dirt, dust or moisture.With a standard tap off unit or cover fitted theIngress Protection (IP) level is at IP54 but higherlevels, up to IP67, can be achieved upon request.More information on the tap off unitsavailable from ABB can be found inour Tap Off Brochure.Feeder lengthTap Off CoverStraight length can be supplied at any lengthbetween a minimum of 600mm and a maximumof 3000mm.The table below illustrates the different typesof build arrangement used depending on therating of busbar required for the application.xxxFlatwise ElbowsEdgewise ElbowsCustom ElbowsFlatwise elbows are typically used to make 90 changes in the direction of the busbar system.There are two main kinds, flatwise up andflatwise down.Edgewise elbows are typically used to make 90 changes in the direction of the busbar system.While elbows are typically 90 ABB canmanufacture special angle elbows if necessaryfor both flatwise and edgewise products.These can be used to turn the busbar route upor down if it is running on its edge, or to turn thebusbar left and right if it is running on its flat.Flatwise Elbow (Up or Down)Ratings (Amps)Tap Off SlotsDistribution lengthBusbar Rating(Amps)Construction 45mm6600ADouble603mm145mm05Edgewise Elbow(Left or Right)Busbar Size (mm)Note: The maximum and minimum sizes we recommend are not the limits of what we can produce, but a guildline to help you choose the correctproduct.
