Description
NH fuse link, NH1, in: 50 A, GG, UN AC: 690 V, UN DC: 440 V, front indicator, live grip tabs NH fuse system 3NA, 3ND for selective line and system protection. The NH-fuse system from Siemens as an important component of the SENTRON protective components for electrical installation offers effective personal, device and plant protection through safe shutdown in the event of an overload or short-circuit. In comparison 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 above all by: 1. Combination detectors signal that the fuse is switched off by a clear color change from red to white. 2. More safety when changing through 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 in sizes 000, 00, 0, 1, 2, 3, 4 and 4a available.
