3 Siemens AG 9 BETA Protecting SR Busbar Systems Distribution board components Overview The use of busbar systems with their versatile rail-adaptable connection, switching and installation devices is an ideal and cost-effective electrotechnical enhancement of modern distribution boards due to their small footprint, compact design and quick assembly contacts. Mounting is implemented on longitudinal stays. The busbar spacing is mm I201_ $ Longitudinal stays % Busbar supports, three-phase & Cu busbars ( Terminals ) Support for blanking covers * Blanking cover + Supports, Touch protection cover - Busbar supports, single-phase Benefits Only a few distribution board components are required to ensure the integration of busbars in the distribution board. This saves time and space. The touch protection cover is sealable as standard and is quick and easy to attach to the supports thanks to the use of quick-release locking technology.

The material ensures excellent mechanical, chemical and electrical properties. Furthermore, the material has an extremely low flammability and meets the requirements of UL 94 V0. This satisfies the load requirements of the busbar supports at rated operational voltage 00 V and rated currents at A to 630 A, as well as the rated short-circuit strength 0 ka. Ambient temperatures When dimensioning the busbars based on rated currents, the ambient temperature and the Cu busbar temperature must also be taken into account. The location of the busbar system and its ability to dissipate heat through convection also play a key role in this calculation. Because conditions can vary for each distribution board, the values in the following table serve as a guideline only. However, they must be applied to the entire busbar length. Continuous currents depending on the Cu power rail dimensions and Cu busbar temperatures at 3 C ambient temperature Cu busbar dimensions H D Continuous current for open busbar run Ambient temperature 3 C Continuous current of fuse link Operational class gl/gg mm mm A A As far as other types of upstream protective devices are concerned, please observe the permissible continuous current of the busbar. Siemens ET B1 10/9 /7

8 BETA Protecting SR Busbar Systems Siemens AG 9 Distribution board components Dynamic rated short-circuit strength The electrodynamic load of the busbars depends on the level of short-circuit current, the length of the busbar section through which the current flows, the support spacing of the busbar supports and, of course, on the distance between the busbars themselves. This is because, for example, if an NH fuse system is connected upstream to the busbars in the protective device, the let-through current i D is the maximum current to flow through this protective device. The value i D depends on the maximum system short-circuit current and the current-limiting action of the protective device used. The permissible let-through values of the protective equipment are specified by the manufacturers in the form of a current limitation diagram as a function of the socalled prospective short-circuit current (r.m.s. value of the possible rated short-circuit current for the system). You will find the current-limiting characteristics for the fuse links in the catalog add-on ET B1 AO 8 BETA Low-Voltage Circuit Protection, Characteristic Curves for Catalog ET B1. For busbar supports with busbars of 12 mm to 20 mm, the distance between the holders of the support spacing should be adapted to suit the bars in the distribution board and should not exceed 20 mm if possible. When using busbars of 2 mm, 30 mm, mm to mm, the distance can also be up to 00 mm. In the case of larger distances, subcarriers must be fitted as increased support spacing reduces the dynamic stability. It is essential to ensure that the permissible current carrying capacity of the individual busbars is not exceeded. A center infeed is required in the limit range. However, the infeed can also be carried out at both ends of the busbar.

9 Siemens AG 9 BETA Protecting SR Busbar Systems Overview Rail-adaptable built-in components, such as NEOZED and DIAZED bus-mounting bases, adapters for modular installation devices, LV HRC fuse switch disconnectors and NEOZED busmounting fuse switch disconnectors are made of glass-fiber reinforced, thermoplastic polyester. The material ensures required mechanical, chemical and electrical properties. Efficient power distribution up to 630 A. There are many ways for users to mount the SR busbar system: 1. Mounting in distribution boards The busbar supports are mounted on longitudinal stays. Once the built-in components have been mounted and connected, the touch protection cover (front cover) protects against accidental contact with live parts. 2. Installation in industrial control cabinets The demand for comprehensive touch protection has generated new solutions: built-in components, such as busbar fuse bases Built-in components have integrated reach-through guards, enable the implementation of cost-effective overall solutions. Previously two optional solutions were provided, which can now be replaced using new technology: the touch protection over base and the respective edges, or touch protection by means of partitions. Overall, increased efficiency and cost savings for the plant manufacturer. With fuse holders for cylindrical fuses, size and for American fuses class CC, they can also be deployed in the international plant engineering sector. In addition, Siemens offers a wide range of UL-approved components for the design of switchgear assemblies in accordance with UL 08 A. For further information, see chapter BETA Devices Approved to UL Standard in Catalog LV For the ultimate in user safety and convenience, we also offer fuse holders and connection modules 16 mm² with screwless terminals I2_13634a $ NEOZED bus-mounting base, 3-pole % DIAZED bus-mounting base, 3-pole & SR bus-mounting fuse holder, 3-pole ( NEOZED bus-mounting switch disconnector, 3-pole ) Connection module, three-phase * Adapter for modular installation devices acc. to DIN LV HRC fuse switch disconnector Benefits The direct contact of the rail-adaptable switching and installation devices on the Cu busbars reduces distribution panels and mounting times, and Compared to conventional installation, the transfer resistance of the connections helps prevent unnecessary temperature rises. New touch-protected built-in components ensure comprehensive touch protection without the previously required partitions. International implementation due to UL-approved components.
