SITOR fuse link 400 A - Low Voltage HRC fuse NH2 400A 3NB1234-4KK11 – Siemens – 4001869483757: SITOR fuse link 400 A 3NB1234-4KK11 Size NH2, rated current 400A, voltage type DC, operating class aR (partial range converter protection), front indicator design, SITOR fuse link, with slotted knife contacts, NH2L, In: 400 A, aR, Un DC: 1250 V, front indicator SITOR 3NE, 3NC semiconductor protection fuses protect power semiconductors from the effects of a short circuit. The SITOR fuse system from Siemens, as an important part of the SENTRON protection components for electrical installations, offers effective protection of people, devices and systems through safe shutdown in the event of an overload or short circuit. The area of application also includes frequency converters with fuses in the input and DC link as well as UPS systems and soft starters for motors. The Siemens SITOR fuses are characterized above all by: 1. Super fast switch-off characteristics compared to conventional NH fuses. 2. Power semiconductors are also reliably protected in the event of a short circuit. 3. The Siemens quality standard ensures very good characteristic curve fidelity. 4. SITOR cylinder fuses are approved according to IEC and UL and mostly also CCC and can therefore be used worldwide. 5. Partially suitable for installation in NH fuse bases, in NH fuse switch-disconnectors and switch-disconnectors with fuses. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, installation distributors as well as switches and sockets for the safe, efficient electrical infrastructure in buildings and industry.
