a connecting bus (comb) PIN 1P 40A & nbsp; EH-BB-140 is used for connecting circuit breakers, RCD, dif-machines and other devices & nbsp.; It is designed for certain supply voltage phases and poles to protect the devices by their parallel connection. That is a substitute homemade jumper wire from the mounting. The most advisable its use in large switchboards. It is simple to use and very reliable device. It is durable and complies with international and European standards.
Of course you can in the old used to connect a jumper from the conductive wire, but this method has some significant drawbacks - jumpers often interfere connect electric equipment on DIN-rail level above, extra wires in the electrical look not only aesthetically pleasing, but also often interfere with the closure cap , installation of a long and time consuming (because you need to measure and cut the wires in length, bend, clean, choose a tip, pressurize with the help of pressing tongs, etc.) When mounting using connecting bus (comb), these shortcomings do not have, but there is several advantages - higher quality connection (when connection jumper is represented by two ends of the wire in a nip, the use of & quot; comb & quot; reduces this value to 2 times that positively affects the quality of the contact), it is virtually eliminated overheating pad and related problems in the panel reduces the number of wires, which makes wiring more than on ezhnoy, accurate and intuitive, fast and easy installation which can handle just about any person.
Structurally is an integral copper plate in the plastic insulation with the radiating pins. The plate and the pins are of unitary construction without the joints. This model combs tires - monopolar, the rated current for the device - 40A. It is designed for operation at a temperature of from -60 to + 60 ° C and an average moisture value of no more than 90%. The length of this device & ndash; 1 m & nbsp.; The pins are spaced 18 mm. The maximum number of plug-ins & ndash; 54.
