Low-voltage surge protection devices that protect our investments and ensure sustainable production by preventing lightning effects and electrical problems from affecting the system, namely low voltage surge protectors, are strategic solution partners of our facilities within the scope of IEC 62305 Standard. By sustainable production, we mean the use of low voltage surge protection systems across a wide range, from the smallest industrial product to renewable energy production. So, what are the prices of these highly important internal lightning protection systems?
As the Lightning Protection Center, we manage thousands of products ranging from main panels to sub-panels, from sensitive energy protection devices to communication module protections. Among a wide variety of products, the most important factor is using the right product for the right system in order to provide an optimal solution. In low voltage surge protection systems that spread across different protection levels such as Class B, Class B+C, Class D, and Class C, design is the most important factor affecting cost. Because if the commissioning algorithm is correctly managed in a facility, maximum protection can be achieved at very low cost based on the principle of staged protection. Systems designed without proper analysis both provide incorrect protection and move us away from optimal solutions.
Class B, C and D Surge Protection Devices
The prices of Class B and Class C surge protection devices used in main and sub-panels vary depending on the level of protection and the result of the regional risk analysis. In Class D surge protection devices, Uc and Up values stand out as the main factors affecting pricing. Correctly understanding the design and the system will help us find the most suitable solution and therefore the most accurate price.
However, even depending on the scale of the investment, a low voltage surge protection system does not even correspond to one-thousandth of the total cost. When compared to their function—protecting systems against lightning, sudden overvoltage, harmonics, transient voltage events, and switching surges, providing uninterrupted production, and minimizing system-related failures—surge protection devices are economically advantageous.
