Surge arrester T1/T2, UC 1050 V DC, Imax 40kA short-circuit strength 80A.

PROTECTION PLUG TYPE2 UC 750V AC, FOR 5SD7481-1 AND 5SD7483-5, Surge protection devices for protecting against overvoltage in electrical systems. As an important component of the SENTRON protective components for electrical installations, the surge protection devices from Siemens provide effective protection in the event of lightning and overvoltage due to atmospheric influences or switching operations. User-friendly mounting and connection technology as well as an integrated design are the characteristics of the device family. Whether for infrastructure or for industrial requirements, Siemens provides surge protection devices for all applications and every application area. Key features of the Siemens surge protection devices: 1. Effective investment and plant protection against lightning and overvoltage. 2. The right lightning/overvoltage protection (type 1 to 3) for every use case. 3. Remote signaling contact to the external upload of the status display. 4. Reliable safety during installation due to standard reach-around and touch protection. 5. Removal from standard mounting rail without tools. 6. Clearly visible fault display. 7. The data matrix code on the front of the device provides quick and easy access to information on all aspects of lightning and overvoltage protection. 8. Optimized technology for your safety – only from Siemens. www.siemens.com/overvoltage-protection. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
