Siemens Sentron 3NC3 NH3 Sitor Fuse

SITOR fuse, with slotted blade contacts, NH3, In: 1600 A, aR, Un AC: 500 V, Un DC: 440 V, front indicator. SITOR 3NE and 3NC semiconductor fuses protect power semiconductors from the effects of short circuits. As an essential element of SENTRON's protective component line for electronic installations, the SITOR fuse system from Siemens offers effective protection for personnel, equipment, and facilities with reliable shutdown in case of overload or short circuit. The application area also includes frequency converters with fuses in the input circuit and in the DC-link as well as UPS systems and soft starters for motors. Key features of Siemens SITOR fuses: 1. Extremely fast-acting extinguishing characteristic compared to conventional LV HRC fuses. 2. Power semiconductors are also reliably protected in case of short circuits. 3. Siemens quality standard ensures very good characteristic curve precision. 4. SITOR cylindrical fuses are approved according to IEC and UL, and largely also CCC, and can therefore be used worldwide. 5. In some cases suitable for installation in LV HRC fuse bases, in LV fuse disconnectors and switches with fuses.
