The bus zero 6х9 4/1 EH-BT6941 from the Electro House company is intended for electrical and mechanical connection of zero, protective and phase conductors. It has one opening for installation located on the center of the bus. Is established on the isolation center. This product differs in high quality, reliability and durability. Conforms to the world and European quality standards. Today it is just impossible to present assembly of an electric board without use of similar devices. Use of this product will significantly facilitate work of electricians and will make it safer. If earlier reliable and trouble-free operation of OUZO was ensured by installation of single zero buses to each single device of protective shutdown, then now it is possible to bring the general zero wire to the bus and already from it to part from the block created thus to other components of the created system. Thanks to it reliability and safety of all system in general increases. Structurally this model represents a conducting core without isolation. The conducting core is made of electrotechnical brass and comprises openings with jack screws for fastening of conductors in it (4 cable outputs) and has length of 38 mm, width of 6 mm and height of 9 mm. Diameter of openings for mounting of conductors of 5 mm. Rated voltage for this model - 400B. Rated current - 100A. Working temperature for this product from-40 to 50 ° C with an average a relative humidity no more than 90%. For long and reliable operation an ambient air should not be littered vapors of salts, the corrosion or igniting gases. For ensuring high-quality connection and also simplification of further service, the bus is executed by a uniform conducting element. Its mounting is simple and does not take a lot of time.
