The SITOR 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. The area of application also includes frequency converters with fuses in the input and DC intermediate circuits, as well as UPS systems and soft starters for motors. The main features of the Siemens SITOR fuses are: 1. Super quick cut-off 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 cylinder fuses are IEC and UL approved and, for the most part, also CCC approved 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. 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.
