Surge protector VCX PV50 DC class T1T2 (B+C) 3P 1000V 12.5 kA GDT with gas spark gap

Product detailed description

Technically advanced surge protector with gas spark gap acting as a class B and C surge protector. It is a cutting-edge and innovative lightning protection solution for photovoltaic installations. The protector, which is made using a special high flow varistor (MOV) and a gas spark gap (GDT). Therefore, using one or two varistors can meet the standards that other manufacturers need to achieve multiple varistors. Using fewer varistors will reduce the size of the protector. Our protector is 18 mm/1 pole wide and the total width of the 3 poles is only 54 mm. The surge protector is equipped with varistors (MOV) in the DC+ and DC- modules and a gas spark gap (GDT) in the PE module, which effectively eliminates the problem of varistor aging due to the so-called leakage current and operating current. In summary, the VCX-50PV-B+C class T1T2 protector is: - A special varistor with high flow rate. - Gas discharge tube (GDT) in PE module. - Patented cut-out system. - Y-shaped base. - Extremely precise and advanced internal structure. - Manufactured by varistor-spark technology (MOV+GDT+MOV). The protector is equipped with varistors (MOV) in the DC+ and DC- modules and a gas spark gap (GDT) in the PE module, which effectively eliminates the problem of spark gap aging due to the so-called leakage current and operating current. They are equipped with a visual operation indicator (green - protection, red - no protection). WHY CHOOSE the VCX-50PV-B+C class T1T2 protection device Iimp (Itotal) = 12.5 kA? In the internal design of competitive protectors, 3 varistors are used. This necessitates a width of 36 mm per pole to achieve T1T2 Iimp = 7 kA or more. The total width of the three poles is therefore a full 108 mm! Our protector is 18 mm/1 pole wide and the total width of the 3 poles is only 54 mm.

Protects the distribution network, from the effects of atmospheric surges. - Class B - Lightning arrester - reduces the voltage and limits the energy of a surge wave caused by a direct or indirect lightning strike, the main protective element is a spark arrestor (lightning arrester). The construction is usually multi-part, consisting of a base and replaceable disposable modules, with optical status indication. It is installed as close as possible to the interface between the protected and unprotected environment, i.e. at the entrance of the supply cable to the building, usually in the junction boxes or the main meter cabinet. - Class C - Surge Arrester - limits surges caused by indirect lightning strikes and switching processes in networks. It is used as the second stage in a three-stage protection system. Protection is provided by a spark arrestor or by a solid-state varistor or transistor. The protection is provided once, after disconnection the arrester must be replaced. In the case of a modular design, only the disconnected module is changed. It is installed in the branch substations of the dwellings at a distance of at least 15 m (cable length) from the class B arrester. - Class D - Surge arresters designed for the protection of highly surge sensitive equipment. Reduces voltage and limits surge energy caused by indirect lightning strikes or network switching processes. Use in residential and commercial applications as the third stage (soft protection) in a 3 stage surge protection system. Single protection provided by a semiconductor varistor or transistor. Installation must be made as close as possible to the protected equipment, usually in the form of sockets or extension leads with optical or acoustic switch-off signalling. Overvoltage - division - Switching overvoltages - internal influences, influenced by switching processes in the network. - Atmospheric voltages - external influences, most often a lightning strike on the power grid. Why get a surge protector? At first glance, the purchase of surge protectors seems like a significant investment. However, if you are hit by a switching or atmospheric surge, the investment in a surge protector is a small amount compared to if your appliances (TV, fridge or washing machine) are irreparably damaged or your wiring burns out. For proven electrical surge faults, appliance manufacturers do not accept claims. If you are building a new house today, having surge protection installed is desirable. When lightning damage occurs, surge protection plays a big role in whether or not an insurance claim will be made. For this reason, getting a surge protector is a highly cost-effective investment that will secure your home. NOTICE Due to the risk associated with possible incorrect connection of the equipment, we recommend that installation is carried out by a qualified person with an electrical qualification. We are not responsible for improper wiring and any damage caused by it.
