The DEHNguard modular surge arrester DG TNS 275 FM is a highly advanced protection device specifically designed for TNS networks. It provides medium protection according to Class II/Type 2 and is designed to effectively divert voltage spikes. With a nominal discharge current of 20 kA (8/20µs), it ensures reliable performance and protects electrical systems from surges. The surge arrester is modular in design, meaning that individual modules can be easily replaced when needed. An external pre-fuse is not required, which simplifies installation and maintenance. The DEHNguard is suitable for an operating temperature range of -40° to +80°C and complies with the standards IEC 61643-11 and DIN EN 62305-4. It is mounted on a 35 mm DIN rail, and the push-in terminals allow for easy connection with conductors ranging from 1.5 to 10 mm². Additionally, the device features a potential-free remote signaling contact that provides extra monitoring options.
