Surge arresters on flat busbars (SPB*/10 PP*) on bare overhead conductors (SPB */10 AlFe*) or on insulated overhead conductors (SPB */10 S*). Surge arrester as per EN 61643-11: 2012 with a nominal discharge current of 10kA and a maximum continuous operating voltage of UC = 280 V, 440 V, 500 V or 660 V. They provide protection against low-voltage overvoltage, they protect in low-voltage overhead power distribution systems – electrical equipment, instruments, switching equipment of distribution transformers and reduce the risk of damage to in-house networks and their equipment by atmospheric and switching overvoltage in AC networks with a frequency of 48-62 Hz. The SPB surge arresters protect against the destructive effects of lightning and switching overvoltage. It is recommended to use them in places secured against contact, e.g. by a position or barrier.
Are representatives of a wide range of surge protection devices Class 2 + 3 according to EN 61643-11: 2012 and IEC 61643-11: 2011 for general use in AC supply nets. Having a high absorbency at the disposal of interference voltage components propagating along the lines of the result of the switching processes alternatively due to the effects of storm activity. SPD can be applied without the use of DIN rails even in places where there is a tight installation space, as well as an additional measure in applications where the occurrence of overvoltage operates during operation problems. Acc. to customer’s demand is possible to supply this protection device for max. continuous AC operating voltage UC from 17 to 510V.
