5SD7463-1 SIEMENS

The 5SD7463-1 SIEMENS is a surge arrester designed to protect electrical systems from transient overvoltages. It is a Type 2 surge arrester, also known as a Class C surge protective device (SPD), suitable for installation in secondary distribution panels. This surge arrester is specifically designed for TNC systems (Terra Neutral Combined), a type of electrical earthing system. It features a 3+0 circuit configuration, meaning it has three protected phases and a neutral connection without a dedicated neutral conductor protection. The maximum continuous operating voltage (UC) is 350V. The 5SD7463-1 utilizes pluggable protective modules, allowing for easy replacement in case of failure or end-of-life. It is a 3-pole surge arrester, protecting three phases of the electrical system. A remote display is included, providing real-time status indication and fault monitoring. This feature enables convenient supervision of the surge arrester's operational status and facilitates timely maintenance.
