PSC SQUARE BODY 690/700 Volt SEMICONDUCTOR PROTECTION FUSES

Transcription

1 PSC SQUARE BOY Ferraz Shawmut 690/700V PSC fuse-links provide maximum flexibility in equipment design and ultimate protection for today s power conversion equipment. These square body fuse-links are available in four different body sizes, each size having seven worldwide acceptable mounting styles. The different mounting styles and body sizes along with a broad range of ampere ratings allow greatest flexibility in equipment design. The Ferraz Shawmut PSC fuses have been engineered to provide state-of-the-art protection for SCR s, diodes, thyristors, GTO s and IGBT devices. They have pure silver, die-cut elements embedded in solidified sand, which helps control arcing characteristics for low I 2 t and high interrupting rating. All contact surfaces are silver plated and all hardware is non-magnetic. All fuse links are equipped with a low voltage trip-indicator. This trip-indicator can operate a field mountable microswitch which is easily mounted directly onto the fuse even while in service. HIGHLIGHTS: Extremely Fast Acting Current Limiting Very Low I 2 t Worldwide Acceptability Superior Cycling Ability Ratings AC: A VAC 200 ka IR C: Consult Factory APPLICATIONS: Protection of rectifiers, inverters, C drives, UPS Systems, reduced voltage motor starters, and other equipment in globally accepted applications Approvals UL Recognized Component File E76491 Sizes 30, 31,32, 33 tested to IEC Features/Benefits Choice of mounting styles gives wide choice for equipment design Broad range of ampere ratings in a given body size for design flexibility IEC compliance for worldwide semiconductor applications * For Microswitch information see page J8 North American Reference Numbering System A 070 UR 31 I 350 A.C.
