PSC 1250/1300 Volt SEMICONDUCTOR PROTECTION FUSES Ferraz Shawmut 1250/1300V 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 four 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 I2t 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: APPLICATIONS: Extremely Fast Acting Protection of rectifiers, inverters, DC drives, UPS Systems, reduced voltage motor starters, and other equipment in globally accepted applications Current Limiting Very Low I2t Worldwide Acceptability Superior Cycling Ability Ratings AC: 50-1800A 650-1300 VAC 100 kA IR DC: Consult Factory 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 269-4 compliance for fuses for worldwide semiconductor applications Approvals *For Microswitch information see page J10 UL Recognized Component Sizes 70,71,72,73 tested to IEC 269.4 * Contact technical services for applications data.
