The CP V 40 and CP VH 40 surge arresters of arrester class 2 (C) are used for reliable protection of electrical systems. The CP V 40 is designed in two parts and is also available as CP VH 40 with remote signaling as a potential-free changeover contact. In the event of an overload, the integrated monitoring unit signals: the characteristic visible from the outside turns red, indicating that replacement is required as soon as possible. The CP V 40 and CP VH 40 surge arresters are equipped with a dual-function terminal suitable for connection to live conductors as well as comb rails. In addition, variants in 2- and 4-pole versions, e.g. for TT networks, are also available.
Overvoltage protection CONTA-PROTECT
Important for the selection of the right surge protection devices are the VDE regulations VDE 110-1, IEC 61643-1 and EN 61643-11 and VDE 0185 Part 100 with regard to surge voltage resistance, insulation and lightning protection classes.
CONTA-CLIP protection modules comply with the requirements of VDE and IEC, and in some cases even exceed them. New solutions from CONTA-CLIP thus offer many advantages for the user.
Surge arrester CDS 98
The CDS 98 surge arrester of arrester class 3 (D) is used for reliable protection against overvoltages on the power supply lines inside switchgear and control cabinets. With the CDS 98 surge arrester, the overload is signaled by an LED.
