Busbar Supports GENIFLEX®


The universal suitability of the busbar supports for different bar formats greatly reduces stocking needs.

The 3-fold support SH3 has a phase center spacing of 60 mm and can therefore be used for all operating equipment, such as NH isolators or power switches with 60 mm phase spacing.






Busbar Supports GENIFLEX® Technical Data












Short-Circuit current


When it comes to short-circuit current, a distinction is made between surge current and continuous short-circuit current. It is the continuous short-circuit current that is responsible for heating the conductor. It is proportional to the current square I² and the duration of the short circuit t.

 

The surge current generates the maximum force that is exercised on the current-carrying conductors and therefore on the supports. The spacing between two neighboring supports can be changed to absorb the forces of the maximum expected surge current. This dependence for supports SH1 and SH3 is shown in the diagram. With a given current, this permits calculation of the maximum admissible spacing between the busbar supports for different bar formats. The maximum spacing differs between busbar supports.


Surge current

With a Cu bar measuring 30x10 mm and a support spacing of 250 mm, the maximum short-circuit current is 110 kA








SHS Busbar Supports


For upright busbar mounting, 3-pole and 4-pole for 10 mm bars.

The busbar supports are used to create a 3 or 4-pole busbar system with conductor heights from 30 – 100 mm. The bar can have both individual conductors and double conductors per phase. Different phase center spacings permit adaptation of the busbar system to different room dimensions or concepts with different short-circuit strengths. The nominal operating voltage according to IEC 61439 is 1000VAC or 1500VDC.

 

The data on short-circuit current is listed under the link in the info box. The busbar supports are made of glass fiber-reinforced polyamide 6.6 and are self-extinguishing in line with UL 94 V0. The material permits a maximum bar temperature of 120°C and is halogenfree. The top and bottom sections of a support are identical, thereby ruling out the problem of interchanging. The two support sections are connected to each other via threaded rods or threaded bolts. The spacing of the support sections is defined by so-called spacers to suit the bar height.

 

5 supports are required for laying within a switch cabinet. This is why the busbar supports are available in packs of 10, equivalent to 5 supports.

 

The length of the required threaded rods depends on the bar height plus the length for securing of the support on the base structure.




























SHL Busbar Supports


For horizontal bar arrangement, 3-pole and 4-pole for 10 mm bars.

The busbar supports are used to create a 3 or 4-pole busbar system with the conductor dimensions 20/25/30 x 10mm and 20/25 x 5 mm. The nominal operating voltage according to IEC 61439 is 1000VAC or 1500VDC. The data on short-circuit current is listed under the link in the info box.


The busbar supports are made of glass fiber-reinforced polyamide 6.6 and are self-extinguishing in line with UL 94 V0. The material permits a maximum bar temperature of 120°C and is halogenfree. Each support consists of 3 molded parts that can be used to create various conductor widths and thicknesses. The support sections are joined using screws.





3 and 4-pole busbar supports are suitable for the following bar sizes:

30 x 10, 25 x 10, 20 x 10, 25 x 5 and 20 x 5








For mounting use M6 Screws.






SHK Flat Busbar Supports


Flat horizontal bar arrangement for bar widths of 3, 5, 6, 8 and 10 mm..

The innovative design allows the use of 5 different bar thicknesses with one bar support. Combination of individual supports permits the creation of 3, 4 and 5-pole systems.

 

The bar width can be varied between 25 and 80 mm without the need to use additional adapter pieces. The nominal operating voltage according to IEC 61439 is 1000VAC or 1500VDC. The all-round character of the supports paves the way for an easy-to-install, lightweight and cost-effective solution for the creation of a bar system.



The busbar supports are made of glass fiber-reinforced polyamide 6.6 and are self-extinguishing in line with UL 94 V0. The material permits a maximum bar temperature of 120°C and is halogenfree. A support consists of an upper and lower section.

 

The two support sections are connected by a threaded bolt which simultaneously secures them on the base structure. The spacings of the support sections can be chosen in line with the short-circuit strength. The data on short-circuit current is listed under the link in the info box.





The desired conductor thickness can be achieved by coordinating the positions of the top and bottom sections relative to one another. The diagram shows you how to do this:










VMS Busbar Supports



For upright bar arrangement, for 10 mm bars with 2 or 3 conductors per phase.

 

The busbar supports are used to create a 2, 3, 4 or 5-pole busbar system with conductor heights from 30 ? 120 mm and bar thickness of 10 mm. The bar system can have double or triple conductors per phase or just one conductor per phase. Different phase center spacings permit adaptation of the busbar system to different room dimensions or concepts with different short-circuit strengths. The nominal operating voltage according to IEC 61439 is 1000VAC or 1500VDC.

 

The busbar supports are made of glass fiber-reinforced polyamide 6.6 and are self-extinguishing in line with UL 94 V0. The material permits a maximum bar temperature of 120°C and is halogenfree. The top and bottom sections of a support


are identical, thereby ruling out the problem of interchanging. The two support sections are connected to each other via threaded rods. The spacing of the holder sections adapts automatically to the bar height. The phase center spacings can be extended using spacers from 110 mm to 130 mm to ensure clear spacing between neighboring phases. In addition, the larger structure of the individual supports permits any desired phase spacing dimension above 130 mm. This means that correspondingly high short-circuit currents can be absorbed.

 

The data on short-circuit current is listed under the link in the info box. The length of the required threaded rods depends on the bar height plus the length for securing of the support on the base structure.










Low-Voltage Busbar Plugs


The NS250 and NS400 busbars plugs are designed to serve as screwless, removable connectors for the contacting of 5mm and 10mm copper and CoppAl® bars.

 

The spring contacts are made from a high strength and highly conductive silver-plated


copper alloy. The surrounding casing is made from glass fiber-reinforced polyamide 6.6 with its known outstanding properties. For the purpose of conductor contacting, the plug connector can be used with a max. temperature of 105°C and complies with IEC 61439.





1 The aforementioned current was tested with an increase of 30 k above the ambient temperature of 35° C in accordance with IEC 61439.



Both connectors have the same outer dimensions and are suitable for the same mounting parameters:

Total length: 112mm
Connector insert length after mounting: 80mm
Connector width: 48mm
Thickness of mounting plate: 1.5 - 3 mm


We recommend the use of contact grease for plug connections.


N.B. Plug connectors may only be connected and disconnected in no-load state!



Low-Voltage Busbar Plug


Recommended cutout for the plug connectors






Bushing Insulator



Each B4 bushing insulator is used to route bars in 4 formats through casing walls, switchgear sections and mounting plates.

 

B4-30 can be used for bars up to 30x10mm and B4-50 for bars of sizes up to 50x10mm. The B4-30 and B4-50 bushings can route bars both upright and horizontally, and can also be twisted into any angle position. This is what sets the B4-30 and B4-50 apart from similar bushing insulators.
