Surge protector VCX PV30 DC class T2 (C) 3P 1200V

Product detailed description

The VCX PV30 DC class T2 (C) 3P 1200V 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 combination of varistor and spark gap technology, it provides an excellent ability to dissipate extreme current surges, which significantly increases the safety of the entire installation. Surge protector VCX PV30 DC class T2 (C) 3P 1200V Advantages over conventional surge protectors - Combination of varistor and spark gap = better surge dissipation capability - High maximum current carrying capacity of up to 40 kA - Optical status indication increases operational safety and reduces service costs - Compact, 3-module design saves cabinet space - Specially designed for photovoltaic applications with voltages up to 1200 V DC Maximum safety thanks to spark gap technology Compared to conventional varistor protectors, the VCX PV30 offers an integrated spark arrestor, which enables more efficient handling of high overvoltage currents (e.g. from lightning discharges). This design results in higher reliability, longer life and lower risk of failure under extreme conditions. This makes the product an ideal choice for demanding applications where protecting the investment in the solar system is critical. Quick visual inspection of the device's condition The device is equipped with a visual status indicator that lets you know immediately if the surge protector is fully operational. Green indicates active protection, red indicates the need to replace the module. This simple but very effective mechanism saves time and trouble during regular maintenance. Practical use and easy installation This surge protector is designed for direct use in the DC parts of photovoltaic power plants up to a maximum voltage of 1200 V DC. It is suitable for small domestic systems as well as for larger rooftop installations. The compact dimensions (3P) and the possibility of connecting conductors up to 35 mm2 make installation easy and flexible. The IP20 degree of protection ensures sufficient protection for installation in control cabinets. 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. Technical product specifications: Protection Class: T2 - Corresponds to protection against medium surges, e.g. lightning strikes indirectly struck in the vicinity. Varistor with integrated spark gap (MOV-GDT-MOV) - Increases the ability of the device 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. Voltage protection level (Up): < 4 kV - The low protection threshold minimizes the risk of damage to 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-module design allows compact installation. Safety instructions for installation and operation: The use of the VCX PV30 DC T2 1200V surge protector requires observance of basic safety rules. Before installing or servicing the equipment, we recommend paying attention to the following instructions: - Installation, maintenance and any replacement must only be carried out by a qualified and authorised person. - All applicable local, regional and national regulations must be observed during installation and use. - Opening the unit or any tampering with its construction will void the warranty. - Overloading above the manufacturer's recommended values may result in permanent damage to the equipment and connected components. - The device may only be operated under the conditions specified in the technical documentation. - Always disconnect the power supply before any intervention in the device. Following these guidelines will prevent unintentional damage and ensure long and reliable operation of your system.
