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.
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 I 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
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 120C and is halogen free. 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.

We cover a huge range of electrical enclosures, Our Enclosures adhere to the IEC's standards for determining enclosures' capabilities. Their International (or Ingress) Protection IP rating system defines an enclosure's protective capacity, and then assigns an IP Code. The code labels an enclosure's IP followed by two numbers; the first digit shows the extent to which equipment is protected against particles, and the second digit indicates the extent of protection against water. Our IP54 enclosures have a high level of protection against particles, and a fair amount of protection against water. All of our enclosures rigorously comply with the guidelines, so you can count on quality and cost-efficient enclosures.Our most common IP ratings are probably 65, 66, 67 and 68. So for quick reference, these are defined below:
IP65 Enclosure- IP rated as "dust tight" and protected against water projected from a nozzle.
IP66 Enclosure- IP rated as "dust tight" and protected against heavy seas or powerful jets of water.
IP 67 Enclosures- IP rated as "dust tight" and protected against immersion.
IP 68 Enclosures- IP rated as "dust tight" and protected against complete, continuous submersion in water.

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.
A Miniature Circuit Breaker (MCB) is a device that switches and/or protects the lowest common distributed voltage in an electrical system. It is designed to protect conductors and insulation from damage due to overload and short circuit.Miniature circuit breakers are not just for residential applications only. They are used in residential, commercial and industrial applications.In an industrial or commercial application, miniature circuit breakers can be found in load centers, lighting panel boards and individual mountings.
A DIN rail is a standardized thirty five millimeter wide metal bar that has a hat-shaped cross section which is widely used for mounting circuit breakers, relays , meters etc and industrial control equipment inside equipment racks. The abbreviation "DIN" stands for DeutschesInstitutfrNormung, the German organization of standards that defines the size and shape of DIN rails. A DIN rail's length can be cut as needed by the person installing the rail and circuit breakers
The standard DIN rail used is 35mm wide. However, there are types of the rail having lesser widths such as 15mm or 7.5 mm.
The European Standard EN 50022 and the IEC standard 60715 specify the DIN rail for mounting low voltage switchgear and control gear.
A residual-current device (RCD), or residual-current circuit breaker (RCCB) or residual twin-direct current couplet (R2D2), is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor. Such an imbalance may indicate current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. RCCBs are designed to disconnect quickly enough to prevent injury caused by such shocks. They are not intended to provide protection against overcurrent (overload) or all short-circuit conditions.
