Siemens Sentron 3NE1 NH1 Sitor Fuse

SITOR fuse with blade contacts, NH1, In: 315 A, gR, Un AC: 690 V, Un DC: 250 V, front indicator SITOR 3NE and 3NC semiconductor fuses protect power semiconductors against the effects of short circuits. As an important element in SENTRON’s protective component line for electronic installations, the SITOR fuse system from Siemens provides effective protection for personnel, equipment, and installations with reliable shutdown in the event of overload or short circuit. The application range 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 cut-off characteristic compared to conventional LV HRC fuses. 2. Power semiconductors are also reliably protected in case of a short circuit. 3. Siemens quality standard ensures very good characteristic curve accuracy. 4. SITOR cylindrical fuses are approved according to IEC and UL and mostly also CCC and can therefore be used worldwide. 5. In some cases suitable for installation in LV HRC fuse bases, in LV fuse switches, and disconnectors with fuses.
