Power Distribution Unit

An example is the introduction and the Russian Automatic AP50 (in fairness, quite reliable) – black rectangular box with two (red and white) buttons in the lower right corner. Boxed unit take up much space and are forced to increase the size of the shield, so where permissible, use modular instruments. Major recent standardized mounting dimensions (width 17,5-18 mm, depth of the plane inner side of the closing panel to the mounting plane 58 mm, total height is not more than 96 mm, the protruding part with the organs of control and is located in the center) and typically do not vary from manufacturer to manufacturer. Enclosure device is installed horizontally in a row on a special metal profile (35 mm DIN-rail). Thus, they form one single entity, and may close the general panel, which leaves access to controls. The only exceptions are modular circuit breakers in a 60-26 (Tiraspol plant) width 12,5 mm.

They deserve special mention due to the fact that they allow to put in a limited-size Power Distribution Unit larger number of machines. counters These devices, designed to accommodate electricity. If fifteen years ago at the mention of this device, we were black device with a round glass, followed by a variable speed (depending on consumption), rotate the wheel with a label that Today things are not so simple. New technical solutions significantly revitalize the market, but before you consider specific models, we give some details on which can be classified into these products. The most important 'Class-sign' is the appropriate instrument Mains – different counts for three-phase 380 V for single-phase voltage of 220 V.
