SURGE ARRESTER T2, UN 240/400V, UC 350/264V ac, PROTECTION MODULES PLUG-IN, 3+1 CIRCUIT (TN-S, TT), WIDTH 49.2MM Surge protection devices to protect against surges in electrical systems. The surge protection devices from Siemens, as an important part of the SENTRON protection components for electrical installations, offer effective protection against lightning and surges 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 use. The Siemens surge protection devices are characterized by: 1. Effective investment and system protection against lightning and surges. 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 grip and contact 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.
