SITOR fuse insert with knife contacts, NH0, In: 40 A, gR, Un AC: 1000 V, Un DC: 250 V. Front indicator semiconductor protection fuses SITOR 3NE, 3NC protect power semiconductors from the effects of a short circuit. The SITOR fuse system from Siemens is an essential component of the SENTRON protection devices for electrical installations and provides effective protection for people, equipment, and systems through safe disconnection in the event of overload and short circuit. The application range additionally includes frequency converters with fuses in the input and DC intermediate circuit, as well as UPS systems and soft starters for motors. Siemens SITOR fuses are particularly characterized by: 1. Super-fast tripping characteristics compared to conventional NH fuses. 2. Power semiconductors are also safely protected in the event of a short circuit. 3. The Siemens quality standard ensures very good characteristic curve fidelity. 4. SITOR cylindrical fuses are approved according to IEC and UL, and largely also CCC, making them suitable for worldwide use. 5. Partially suitable for installation in NH fuse bases, in NH fuse load disconnect switches, and load disconnect switches with fuses. Siemens offers a comprehensive portfolio of protection, switching, measuring, and monitoring devices, installation distributors, as well as switches and sockets for a safe, efficient electrical infrastructure in buildings and industry.
