Siemens 3NE12270 Fuse holder inset with blown fuse indicator Suitable for Fuse size 000 - 4 Fuse size = 1 250 A 690 V 3

SITOR fuse link, with blade contacts, NH1, in: 250 A, GS, UN AC: 690 V, UN DC: 250 V, front-end indicator semiconductor 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 protective components for electrical installation offers effective personal, device and plant protection by safely shutting down in the event of an overload or short-circuit. The range of application also includes frequency converters with fuses in the input and DC DC link as well as UPS systems and soft starters for motors. The Siemens SITOR fuses are characterized above all by: 1. Super-fast switch-off characteristics in comparison to conventional NH-fuses. 2. Power semiconductors are also protected against short-circuits. 3. The Siemens quality standard ensures a very good level of loyalty to the experts. 4. SITOR cylindrical fuses are approved according to IEC and UL and for the most part also CCC and can therefore be used worldwide. 5. Partly suitable for installation in LV HRC fuse bases, in LV HRC fuse switch disconnectors and switch disconnectors with fuses.
