## Long description

The Siemens 5SD7464-1 is a high-performance Type 2 surge arrester engineered to provide robust protection for electrical installations against transient overvoltages. Designed specifically for 3+1 TN-S network configurations, this 4-pole device effectively diverts excess energy to ground, safeguarding sensitive electronic equipment and infrastructure. With a discharge capacity of 20kA and an operating voltage of 350V, it offers a reliable solution for maintaining electrical system integrity in both residential and industrial environments.
Advantages
This surge arrester stands out due to its integrated signaling contacts, which allow for real-time status monitoring and remote notification of the device's operational state. Its compact 4-pole design facilitates easy integration into standard distribution boards, while the high-quality construction ensures long-term durability and consistent performance under varying electrical conditions. By mitigating the risks associated with voltage spikes, it significantly reduces the likelihood of equipment damage and downtime.
Suitable for
Residential electrical distribution boards
Industrial automation and control systems
Commercial building power protection
TN-S earthing system installations
When it may not be suitable
This device is specifically designed for TN-S systems and may not be compatible with other earthing configurations without appropriate modifications. It is not intended for use as a primary lightning protection system in areas with high direct strike exposure, where Type 1 arresters are required.
