1 Main characteristics 6,9 grb 7 PA 6,9 grb 73 TTF MS7V-5 UR Ferraz Shawmut PSC-gRB 690 VAC fuse-links provide maximum flexibility in equipment design and ultimate protection for today s power conversion equipment. This range is a fast acting, full range fuses engineered to provide state of the art protection for power semiconductors such as diodes, thyristors. These square body fuse-links are available in various body sizes with a broad range of ampere ratings allowing the greatest flexibility in equipment design. They have pure silver fuse elements embedded in solidified sand which provides optimized I 2 t and high breaking capacity. All contact surfaces are plated and all hardware non-magnetic. All fuses are standard with a low voltage blown fuse indicator. This indicator can operate a microswitch which is easily mounted directly on to the fuse in service. 6,9 grb 70 EF Feature Full range (gr curve), fast acting Highly current limiting. High breaking capacities Very low I 2 t Worldwide mounting acceptance. Superior cycling ability. High widstanding in rush current and overloads Ratings 6,9 grb 73 DIIA 000 AC: up to 000 A 690 VAC 50 ka IR DC: Consult Factory Applications Protection of rectifiers, inverters, static switch, AC & DC drives and UPS systems. AC: Tested to IEC approvals Features /Benefits Wide range of mounting styles Broad range of ampere ratings in each body size for design flexibility IEC compliance for fuses for worldwide semiconductor applications SCAC2 2/04
