Product details

NH fuse link, NH1, In: 20 A, gG, Un AC: 500 V, Un DC: 440 V, front 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 case of overload and 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 when changing the fuse due to insulated handle lugs. 3. High selectivity at low cost. 4. Long-lasting and safe operation due 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.
