The bus the zero isolated EH-BNC-8 on eight openings from the Electro House company is intended for electrical and mechanical connection of zero, protective and phase conductors. 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. Structurally this model represents a conducting core in the isolating case from the self-fading plastic. The conducting core is made of electrotechnical brass and comprises openings with jack screws for fastening of conductors in it (eight cable outputs with a diameter of 5.5 mm). Width - 11 mm, length - 95 mm). Rated current for this model - 100 A. 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 of this product 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. The case has two openings for screw fastening on a surface. It is necessary to make for the correct functioning of devices of differential protection correctly their connection, and in a distribution frame to divide N conductors from PE. In case of a metal board, it can be made only having isolated a zero conductor from the case. Thanks to design features, this model will be suitable for execution of such task as well as possible - as it is already isolated by the case and does not demand installation on the isolation center. Its mounting is simple, does not take a lot of time and does not demand an additional equipment.
