NH fuse link, NH000, In: 25 A, gG, Un AC: 690 V, Un DC: 250 V, combi-indicator, live handle lugs NH fuse system 3NA, 3ND for selective line and system protection. The NH fuse system from Siemens is an important component of the SENTRON protection components for electrical installations, offering effective protection of persons, equipment, and systems through safe disconnection in the event of an overload or short circuit. Compared to miniature circuit breakers, higher short-circuit currents can be realized with better current limitation at the same time. The NH fuse system is characterized by: 1. Combination detectors signal the switching off of the fuse by a clear color change from red to white. 2. More safety during changing due to insulated handle lugs. 3. High selectivity at low cost. 4. Long-term and safe operation due to silver-plated contact blades. 5. Fuse links from 2 A to 1250 A and in sizes 000, 00, 0, 1, 2, 3.
