Surge arrester type 2 requirement class C, UC 350V protective modules pluggable 1-pole, LN circuit Surge protection devices for protection against overvoltages in electrical systems. The surge protection devices from Siemens, as an important component of the SENTRON protection components for electrical installations, offer effective protection against lightning and overvoltages as a result of atmospheric influences or switching operations. Convenient assembly and connection technology as well as a consistent design are the hallmarks of the device family. Whether for infrastructure or industrial requirements, Siemens offers surge protection devices for all applications and every area of application. The Siemens surge protection devices are characterized above all by: 1. Effective investment and system protection against lightning and overvoltages. 2. The right lightning and surge protection for every application (type 1 to 3). 3. Remote signaling contact for external upload of the status display. 4. Reliable safety during installation thanks to the anti-touch and anti-reach protection included as standard. 5. Can be removed from the top hat rail without tools. 6. Clearly visible error display. 7. Data matrix code on the front of the device provides all information about lightning and surge protection quickly and easily. 8. Optimum technology for your safety - only from Siemens. www.siemens.de/ueberspannungsschutz. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe, efficient electrical infrastructure in buildings and industry.
