The Siemens 5SD7412-2 is a robust lightning arrester designed to safeguard electrical systems from the detrimental effects of overvoltages, particularly those caused by lightning strikes and power surges. This part is an essential component for maintaining the integrity of 3-conductor networks (L, N, PE) and is suitable for use in both commercial and industrial settings.
Crafted to meet the rigorous standards of IEC 61643-11: 2011 and EN 61643-11: 2012, the 5SD7412-2 is classified as a Type 1 surge protection device, indicating its capability to handle substantial surge currents up to 12.5 kA. Its continuous operating voltage is rated at 335V/264V AC (L-N/N-PE), ensuring compatibility with a wide range of network voltages.
The device features a clear mechanical defect indication, allowing for easy status checks and maintenance. Its compact design, with a size of 2 TE, makes it an unobtrusive addition to any electrical setup, while the DIN rail mounting method ensures a secure and straightforward installation process.
The 5SD7412-2 is constructed from high-quality materials, including an enclosure made from PA 6.6 / PBT, which provides a degree of pollution of 2 and an overvoltage category of III. The protection class IP20 ensures that all terminal connections are safeguarded against the ingress of solid objects.
With an ambient operating temperature range of -40 °C to 80 °C and a relative humidity tolerance of 5% to 95% during operation, the 5SD7412-2 is built to perform reliably in a variety of environmental conditions. Its installation altitude capability extends up to 2000 metres above sea level, further enhancing its versatility.
In summary, the Siemens 5SD7412-2 lightning arrester is a dependable and efficient solution for protecting electrical systems against the risks of overvoltages, ensuring the longevity and reliability of your electrical infrastructure.
