Eaton Engineering Services Busbar Trunking System
Specification
Eaton’s Mempower Busbar Trunking System is the obvious choice when
searching for a combination of technical performance and attractive
design. Constant development of the range for over 30 years has not only
ensured economical and reliable solutions; Mempower has evolved into an
unsurpassed range able to adapt to virtually any installation. Mempower
is an integral part of the product offering from Eaton Electric Limited.
Complementing the Eaton range of low voltage distribution equipment from
packaged substations and LV distribution switchboards to a complete
selection of fused switchgear, circuit breaker systems, motor control
gear and OEM products, Eaton is your source of circuit protection &
control – worldwide.
Mempower Busbar Trunking Systems are thoroughly tested and comply fully
with IEC 60439-2. The range extends from 25–6300A with lighting, low,
medium and low impedance power versions, together with a wide selection
of accessories and tap-off units. The straightforward and highly styled
design makes Mempower Busbar Trunking easy to both install and use –
truly the system with style!
The advantages of Mempower Busbar Trunking are impressive, hence its
popularity in replacing conventional cabling systems. Not only does its
unique design provide a neat and attractive alternative to cable and
many other busbar brands, it also ensures flexibility and ease of
installation in terms of jointing and fitting. With no requirement for
cable trays and complicated terminations, all Mempower ranges are
supplied in convenient 3m lengths (alternative lengths if required),
which can simply be ‘tapped-off’ where required. An entire building can
be fed from a single riser with no need for expensive and complicated
cable runs to each floor. This benefit, along with the ability for
single pole applications, fed from a three-phase system to load balance,
means we can provide both space saving and cost-effective solutions. The
design is completely re-usable and can be easily assembled in any
location in the minimum of time, while tap-off devices are located at
any required point.
The options of circuit protection are themselves numerous with a
comprehensive choice of tap-off devices including fuses (BS, NH, DIN),
switch-disconnectors and switch-disconnector-fuses, MCCBs, MCBs, FCSs
and BS1363 & BS4343 (CEE17, IEC309) industrial plugs and sockets.
Additionally, our wide range of angles and components can be combined to
meet layout requirements without compromising on economy or space.
General Construction
- LUX Strong aluminium housing; tough moulded extrusion containing
rigid copper wires
- LP, MP Aluminium profile with interlocking flame retardant
polyester covers
- XP Aluminium housing, sandwich construction, high-grade
insulation
Enclosure
Degree of protection to BSEN60529 (IEC60529):
- LUX IP41 standard; IP55 on request
- LP IP41 standard
- MP IP41 standard; IP54 on request
- XP IP4X standard; IP54 on request
Conductor Bars
- LUX Four or six copper conductors
- LP, MP Five copper conductors – three phases with separate
neutral and earth providing facility for ‘clean earth’ where
required
- XP Extruded copper 2 to 6 bars giving DP, TP, TP & N,TPN & E,
TPN & E with 200% neutral Voltage Drop
- Refer to individual range technical data tables for details
Insulation
- Tap-off points and support mouldings on the LP range are moulded
polyester classified flammability grade UL-94 V-O with MP & XP
ranges being a LSHF grade UL-94-V-O
Conductor Joints
Each length is supplied complete with all components necessary for
connection to adjacent lengths or fittings
Protective Earth Conductor
- LUX provided by the housing
- LP, MP Separate PE conductor included in the system up to 800A
- XP provided by the housing; an internal PE conductor can be
supplied if required
Straight Lengths & Fittings
Supplied as standard in 3m lengths – shorter lengths, angles,
intersections and special bends are available on request
Incoming Feed Arrangements
- LUX Insulated cable end feed box with cable gland
- LP, MP can be end or centre fed
- XP Transformer and switchboard flange connections plus end
feeders for cables can be tailor-made to customer requirements
Mounting & Supports
- Mempower lighting trunking can be mounted in any plane,
long-face vertical gives maximum strength for luminaire support
- The other ranges can be mounted horizontally or vertically –
universal mounting brackets are available suitable for wall mounting
or suspension
Conductor Expansion
Generally any changes in relative lengths of conductors or housing
are
accommodated for by movement of the joint links and no special
precautions are required
Fire Barriers
Factory fitted internal fire barriers for LP & MP are of the
Intumescent
Gasket type, 4 hr rated to BS476 Part 20. No internal fire barriers are
necessary with XP
Tap-off Units
- Insulated plug-in unit for Mempower LUX
- A variety of plug-in tap-off units are available for the LP & MP
ranges, which are simply clamped into position. LP units are
insulated as standard (metalclad available) while MP is metalclad
- XP tap-off units are metalclad to IP54 as standard
Tapping Outlets
- Every 1m along the face of the LUX range; simple plug-in fixing
with tapping seal for unused outlets
- For LP & MP, automatic shuttered outlets are provided every 0.33
of a metre on the front face of the busbar. The arrangement of
tapping connections and apertures ensures the tap-off units are
fitted correctly. XP tapping outlets can be engineered to the
required position
Standards
Mempower busbar trunking conforms to BSEN60439-2, and IEC60439-2
