Surge Arrester/Controller

Cape Electric Corporation offers surge arrester/controller V20-C, V20-C/…+NPE. These are surge arresters of requirement Class C to DIN EN/IEC 61643-11. These devices protect low-voltage consumer installations from voltage surges of all kinds. They are available in single-pole to four-pole versions. Type V20-C/3+NPE (requirement class C) is a special surge arrester for TN-C-S, TN-S, TT and IT systems. This device was developed for the requirements of DIN EN/IEC 60364, to allow simple, safe installation of the devices. The voltage-dependent active part of the V20-C is a high-performance zinc oxide varistor with a highly non-linear characteristic. Among the advantages of this component are an extremely short response time, a low protection level and a high current diversion capacity, combined with long life. A further feature of these devices is that no follow-up current can be registered after the surge has decayed. If the surge arrester is damaged by overloading, the integral isolating device breaks
