SITOR fuse link, with internal thread on both sides, In: 710 A, aR, Un AC: 900 V, Un DC: 440 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, as an important component of the SENTRON protection components for electrical installations, offers effective protection for people, devices and systems by safely switching off in the event of an overload or short circuit. The area of application also includes frequency converters with fuses in the input and DC intermediate circuit as well as UPS systems and soft starters for motors. The Siemens SITOR fuses are characterized above all by: 1. Super-fast shutdown 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 accuracy. 4. SITOR cylinder fuses are approved according to IEC and UL and mostly also CCC and can therefore be used worldwide. 5. Partly suitable for installation in NH fuse bases, in NH fuse switch disconnectors and switch disconnectors with fuses. www.siemens.de/fuses. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, installation distributors as well as switches and sockets for safe, efficient electrical infrastructure in buildings and industry.
