Surge protector VCX PV30 DC class T1T2 (B+C) 3P 1200V 5kA

Product detailed description

The VCX PV30 DC class T1+T2 (B+C) 3P 1200V 5kA surge protector is the ultimate solution for protecting the DC part of a solar power plant. It is specially designed to reliably protect PV components from the effects of atmospheric phenomena and overvoltages from other sources. Thanks to the three-stage MOV-GDT-MOV technology (varistor + gas spark gap + varistor), it offers an exceptionally high level of safety that will be appreciated by professionals and owners of larger solar power plants. VCX PV30 DC class T1T2 (B+C) 3P 1200V 5kA surge protector One device for both T1 and T2 protection Unlike conventional surge protectors that protect against either lightning currents (T1) or only switching and propagating surges (T2), this model performs both tasks simultaneously. The three-pole design (3P) covers most modern PV installations and is ideal for use on the DC side up to 1200 VDC. Combination of technologies for maximum reliability The protection takes advantage of the combination of varistors and gas spark arrestors to provide: - High impulse resistance up to 40 kA, - The ability to handle lightning currents up to 5 kA (10/350 µs), - Lower risk of degradation due to separation of current paths. The PE gas spark module eliminates the problem of ageing and loss of effectiveness of conventional protection due to long-term exposure to operating currents and leakage currents. Visual inspection without tools On the front of each module you will find a status indicator for functionality: - Green indicates active protection, - Red indicates the need to replace the module. This allows quick and trouble-free inspection of the device without disassembling the enclosure - ideal for service and regular inspection. Easy installation and universal use The VCX PV30 1200V surge protector is compatible with conductors up to 35 mm2, has a compact three-module design and is ready to be installed in standard switchgear cabinets. Its IP20 protection makes it ideal for indoor use, especially in machine rooms, technical rooms or PV system substations. The combined surge protection design uses: - MOV (Metal Oxide Varistor): It reacts to overvoltage by sharply reducing its resistance when a certain voltage is reached, thus diverting excessive current to earth. It is fast and sensitive. - GDT (Gas Discharge Tube) - Gas-filled spark gap: They switch at higher voltages and are able to safely discharge large impulse currents (e.g. from lightning strikes) without causing damage. They have a long service life. - MOV (second layer): Used to further dampen residual voltage and provide smooth closure of the surge pulse. This triple combination of MOV-GDT-MOV brings the advantages of both technologies - fast response, high durability and long life. As a result, it provides more effective and reliable protection than stand-alone varistor or spark gap surge protectors. Why choose this type of surge protector? - Combining T1 and T2 protection in one device - Combination of MOV and GDT technology = long life and high performance - Suitable for modern PV systems with voltages up to 1200 V DC - Optical indication of module status without the need for measurement - High resistance to impulse currents and discharges - Safe and easy installation with wide operating temperature range Technical product specifications: - Protection class: T1+T2 (B+C) Protects against direct and indirect effects of lightning and switching surges. - Varistor with integrated spark gap (MOV-GDT-MOV) Increases the ability of the equipment to effectively dissipate surges, combined surge protection design. - Connection: max. 35 mm2 Allows connection of thicker conductors for higher current loads. - Maximum working voltage (Ucpv): 1200 V DC Designed for higher voltage photovoltaic systems. - Test current (In 8/20): 20 kA Standard ability to repeatedly discharge overvoltage. - Maximum current (Imax 8/20): 40 kA The maximum value that the device is capable of handling in the short term. - Impulse lightning current (Iimp 10/350): 5 kA Special protection against the effects of atmospheric discharges. - Voltage protection level (Up): < 4.5 kV Low protection threshold minimizes the risk of damage to connected equipment. Low residual voltage - higher safety for connected equipment. - Storage temperature: -30 to +70 °C Wide temperature range for safe storage. - Operating temperature: -30 to +50 °C Suitable for harsh climatic conditions. - Protection rating: IP20 Provides protection against contact and dirt when installed in a switchboard. - Number of modules: 3P Three-pole design for full DC+ / DC- / PE protection. Safety instructions for installation and operation: The use of the VCX PV30 DC T1+T2 (B+C) 1200V 5kA surge protector requires observance of basic safety rules.
