NH fuse link, NH4a, In: 1000 A, gG, Un AC: 500 V, Un DC: 440 V, front indicator, live grip lugs NH fuse system 3NA, 3ND for selective line and system protection. The NH fuse system from Siemens as an important component of the SENTRON protection components for electrical installations offers effective protection of people, equipment and systems by safely switching off in the event of an overload or short circuit. Compared to circuit breakers, higher short-circuit currents can be achieved with better current limitation. The NH fuse system is characterized above all by: 1. Combination indicators signal the shutdown of the fuse by a clear color change from red to white. 2. Greater safety when changing thanks to insulated grip lugs. 3. High selectivity at low cost. 4. Long-term and safe operation thanks to silver-plated contact blades. 5. Fuse links from 2 A to 1250 A and available in sizes 000, 00, 0, 1, 2, 3, 4 and 4a. www.siemens.de/schaltgeraete. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, installation distributors as well as switches and sockets for safe, efficient electrical infrastructure in buildings and industry.
