The bus zero in the case (cross-module) of EH-BNS4x15 from the Electro House company is intended for electrical and mechanical connection of zero, protective and phase conductors. It has the case from the heat-resistant self-fading plastic in which the zero buses isolated from each other by partitions are placed and the folding cover from transparent plastic which allows to control visually quality of connection of wires and is also prevented by accidental hit of foreign objects. Also the cover gives protection against accidental touch to current carrying parts of the module. The cross-module has a modern esthetic appearance and the compact sizes. Thanks to this device distributing of cables in an electric board or to an electric cabinet will become not only safer and compact, but also will take more esthetic form. Thanks to visualization of distribution of cables which the cross-module gives repair or installation works will borrow much less time. The bus zero in the case has fastening for installation on DIN a rail that allows to set it within several seconds. Wires are fixed in the zero bus by means of screws that does connection reliable and allows to reuse this device. Thanks to design features the cross-module can be used and as transitional the terminal block for a cable of bigger section if it is necessary to connect several cables of smaller section that is practical and it is convenient. This model of the cross-module consists of four zero buses, each of which contains fifteen cable outputs. Diameter of cable outputs: 2 8.5 mm, 2х7.5 and 11х6 mm for each bus. Its rated current - 125A. Working temperature for this product from-40 to 50 ° C with an average a relative humidity no more than 90%. Section of the connected conductors of 2.5 - 16 mm2. Has a class of protection IP20. For long and reliable operation of the zero bus an ambient air should not be littered vapors of salts, the corrosion or igniting gases.
