Bus connecting (comb) PIN 1P 63A EH-BB-163 from the company "Electro House" is used to connect circuit breakers, RCD, dif-machines and other devices.  It is designed to supply voltage of certain phases and poles to protection devices by their parallel connection. That is, it is a replacement of homemade jumpers from the mounting wire. It is most appropriate to use it in large switchboards. It is easy to use and very reliable device. It is durable and meets international and European quality standards.Of course, you can use the old-fashioned way to connect the jumper from the mounting wire, but this method has a number of significant drawbacks - jumpers often interfere to connect electrical equipment on the DIN rail above the extra wires in the electric panel look not only aesthetically pleasing, but often interfere with the lid closure, mounting longer, more time-consuming (because you need to measure and cut wire to length, bend, strip, choose a tip, pressure-tested with impact tools, etc.) When mounting using the connecting busbars (comb) of these shortcomings there, but there are a number of advantages - a better connection (if the connection of jumpers is represented by two ends of the wire in one clamp, the use of" comb " reduces this value by 2 times, which has a positive effect on the quality of the contact), virtually eliminates overheating of the contact pad and related problems, the number of wires in the shield is reduced, which makes the wiring more reliable, accurate and intuitive, quick and easy installation that almost anyone can cope with. Structurally, it is a solid copper plate in plastic insulation with pins extending from it. The plate and pins are a single structure without connections. This model bus comb-unipolar, rated current for this device-63A. the Number of input conductors-54. The thickness of the conductor is 1.1 mm, and the width is 4 mm. It is designed to operate at temperatures from -60 to + 60 ° C and an average humidity of not more than 90%. The length of this device is 1 m. the Pins are arranged in increments of 18 mm. the Maximum number of plug – ins is 54.
