Signal detector insert 690V - Accessory for fuse base 3NX1021 – Siemens – 4001869216584: Signal indicator insert 690V 3NX1021 size other, type of accessory other, signal indicator lower part AC 690V for NH fuse links size. 00-4 NH fuse system 3NA, 3ND for selective line and system protection. The LV HRC fuse system from Siemens, as an important part of the SENTRON protective components for electrical installations, offers effective personal, device and plant protection through safe shutdown in the event of an overload or short circuit. Compared to miniature circuit breakers, higher short-circuit currents can be implemented with better current limitation at the same time. The main features of the NH fuse system are: 1. Combination detectors signal that the fuse has been switched off by a clear color change from red to white. 2. More safety when changing thanks to insulated grip tabs. 3. High selectivity at low cost. 4. Long-term and safe operation due to silver-plated contact blades. 5. Fuse links from 2A to 1250A and available in sizes 000, 00, 0, 1, 2, 3, 4 and 4a. For safe, efficient electrical infrastructure in buildings and industry, Siemens offers an integrated portfolio of protection, switching, measuring and monitoring devices, distribution boards, switches and socket outlets.
