Description

LV HRC fuse element, NH000, In: 40 A, gG, Un AC: 690 V, Un DC: 250 V, Combined indicator, Insulated grip lugs LV HBC fuse system 3NA, 3ND for selective line and plant protection. As an important component of the SENTRON protective components for electronic installations, the LV HRC fuse system from Siemens provides effective protection for personnel, equipment and plants by means of a reliable shutdown function in the event of an overload or short-circuit. Higher short-circuit currents and better current limitation can be achieved than with miniature circuit breakers. Key features of the LV HRC fuse system: 1. Combination alarms signal the tripping of a fuse by a clear color change from red to white. 2. Greater safety when replacing 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 are available rated from 2 A to 1250 A and in sizes 000, 00, 0, 1, 2, 3, 4 and 4a. www.siemens.com/switching-devices. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution boards as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
