Busbars by FTG
The safe, modern wiring of electrotechnical protection devices (including ground leakage circuit breakers, line circuitbreakers, Neozed, D/D0 fuse mounts, over-voltage and lightning protection devices) is guaranteed using busbars. These bars are available to our customers in 1-pole, 2-pole, 3-pole and 4-pole versions. In addition, the busbars are supplied in cross-sections up to 95 mm², in various shapes (90° curved, E/L/T/Z/SPM/SKN shape) and in versions with a pin or fork. Our products are manufactured in accordance with the standards EN 60947-1:207, EN 61439-1:2011, DIN 60947-1:207 and DIN 61439-1:2011. By using busbars, customers can be sure
that their application is mounted in a way that is safer, more compact, faster and more cost-effective than the outdated methods using cables that have so far been common practice. These products are available as insulated metre busbars in the standard version. Using these busbars, any connections can be cut to the required lengths for fast, flexible connection. When the end covers are then attached, customers have a technically safe product in protection category IP20, for use in individual applications. If customers require, the busbars can be manufactured in the required length or division units in our factory in Triberg. If customers require an even more effective, faster and space-saving busbar system for their application, the Eurovario system
is the right choice for them. The Eurovario system is extremely compact but is just as good as the busbars by the metre in terms of its quality and current-carrying capacity. In addition, the bars are designed in such a way that they can easily be connected by overlapping, if a distribution system needs to be expanded. Overlapping also means that the cross-section can be doubled to up to 50 mm². Busbars in this series are supplied ready for use, since these bars are available in pre-cut lengths. With this series, there is thus absolutely no need for time-consuming cutting, deburring and cleaning. To reduce the assembly time and effort to a minimum and to avoid installation errors, a new generation of the Eurovario system with welded terminal is available.
One Pole Busbar Variants
One pole Eurovario Busbars
The preasembled and fully insulated busbars are simple and easy to use for connecting MCBs.
Busbars with fork or pin lugs
The needed lug design is depending on the MCB in use. FTG offers both fork and pin in different variants, combinations and lengths.
busbars for auxiliary switches
There are also busbars with a bigger pitch, if there are auxiliary switches in use.
As a specialist in busbar pordction FTG also offers busbars for individual applications. Contact us for an offer on special busbars.
Differences in design
There are different busbars feed-in options needed, depending on the used devices. Therefore the FTG busbars can differ in insulation design. The following insulation designs are available depending on the busbar:
Large selection of different criteria
The E design corresponds to the insulation of the Eurovario busbars.
This insulation is fitting for 90° bent copper bars which saves additional space.
The Z design has a feed in offset to the back so the insulation is flush with the devices so additional conducters can be mounted in the back of the busbar (only for one pole busbars).
With the SPM design and a bent copper bar it is possible to save space and achive additional safety when mounting the busbar.
One Pole Busbars for Photovoltaic Applications.
The one pole photovoltaic busbars are available in versions with a feed terminal, press-in nut or threaded bolt. With a busbar cross-section of 35 sqmm, these are used in DC applications up to 1,500 volts DC. With a maximum current rating of 150 A, you can choose between 2 and any number of module units. The fully insulated busbar with feed terminal offers maximum convenience in assembly. With the predefined feed terminal, the currents of the fuse holder can be easily collected and then fed back into the main switch.
The more cost-effective variants, with threaded bolts or with press-in nuts, are more complex in terms of cable assembly, since a cable lug, screw or nut is required. You can find more information about the different versions here.
One to four pole Eurovario Busbars
The Eurovario busbars are not only ready for immediate use, they can also be expanded. If the sub-distribution is added by a unit, the wiring of the circuit breakers can easily be expanded using the same busbar. The video shows two extensions in the sub-distributor.
