Stud Terminals are used in control cabinet construction and in the area of drive motors as connection terminals for high rated currents of up to 240 mm². This is usually used in the area after larger fuses, which is connected to one side of the stud terminal and with the other side to one or more switches distributed. Between the cable lug and the terminal, a tight connection is created thanks to the screw connection. If more motor movements are passed on to the distributor, the terminal scores with a high vibration resistance compared to other techniques.
The versatility of the terminal becomes clear when more outlets are required. Here a combination of several clamps has to be selected in order to distribute from large cross sections to several small outgoing cross sections. For larger cross-sections, the terminal offers the possibility of mounting two cable lugs. For example, instead of squeezing small cross-sections into a cable lug terminals for NH fuse-switch-disconnectors should be used. In addition, if required, two or even three terminals can be connected by a copper bridge.
Alternatively, the compact power distribution block of the PDB+-Series have the same application when four to six outlets are needed. (#STI025 – #STI240)
Auxigaine – The flexible power voltage busbars
FTG offers a wide range of flexible wiring systems. The double-pole Auxigaine busbars are suitable for superstructures up to 1.90m in length and for a maximum current of 125A. In addition, a horizontal and vertical installation is possible.
Thanks to Auxigaine busbars, it is possible to pick different potentials. These are for normal circuit breakers, power supplies or control modules (etc.). Thus, on the DIN mounting rail is more space for resources and there are no terminals necessary. The busbar offers maximum flexibility when potentials have to be changed or when new components are added.
For control cabinet manufacturers, the busbar offers many possibilities to save space, meets UL standards and can be flexibly adapted to the respective requirements.
Vertical busbars horizontally used
For many types of distributors, FTG offers a variety of components suitable as electrical equipment. Especially with high rated currents, the air-insulated busbars according to British Standard are extremely effective in their application.
In some cases it makes sense to apply the vertical busbar horizontally. As seen in the small distributor in the right picture. Here, the Pan Assambly busbar is used to save space in tight applications. Also, the feed is not done from below but above the pins of the busbar.
The so-called Pan Assambly busbars are therefore not only used in domestic installations, but also in solutions such as in industrial distribution boards or in connection with main switches.
BKNA Bow Terminal Series
For collecting a large number of wires in a restricted space
Sometimes, albeit rarely, N and PE conductors have to be collected at a point in controls or switchgear systems. Bimetallic cable lugs are still widely used for connecting supply lines on copper busbars. Holes need to be drilled into the copper busbars at intervals in order to fix the wire with a bimetallic cable lug, which is very time-consuming and expensive.
To collect the power on the copper busbar, clamps are needed that permit simple assembly and disassembly and are compatible with aluminium cable because of the rising price of copper today. Steel clamps of different types can bring large number of lines together on copper busbars. These are a cost-effective option and a better alternative to cable with a bimetallic cable lug, since they require less space and are can be fitted more flexibly and faster.
FTG’s enhancement, the BKNA series, can also be used for aluminium cable, since they incorporate an intermediate plate so that the aluminium and copper do not touch. The intermediate plate also stops the cable from bending by spreading the screw plate load on the cable end. Covers between the positioned steel clamps make the system contact-safe.
Carriers for DIN mounting rails
Compact, clearly laid out solutions are needed for use in control and switchgear construction as N and PE systems. Previously, installing a flexible system was often a complicated affair, and there were no generally applicable components either. For individually required lengths or different busbars, an element was specially designed for better installation. The FTG system carrier is a small, ingenious component. It can be simply clicked onto the DIN rail and fitted with conductors, thus producing a simple, effective power distribution. A particular bonus is that conductors of all types can be inserted in the system carrier. Flexibility is thus instantly combined with effective performance.
A different Type of Distribution
4-pole compact distributor with additional connection option
Distributing energy is often the biggest problem encountered by switchgear cabinet installers. The connection options for potentials are often too far away and unnecessarily long cable routes are often needed. In order to save cable and thus cash, a central distributor is the ideal choice. FTG produces four-pole distributors that can achieve this simply and safely. The distribution block makes wiring easy to trace and, in particular, keeps it tidy. The distributor is available in various sizes and options. A flexibly applied clamp provides for additional clamp points.
