NH Solid Blades 690 VAC sizes 000 to 3

Transcription

1 NH Solid Blades 6 VAC sizes 000 to gs-class Protistor NH 6 VAC fuse-links provide maximum flexibility in equipment design and ultimate protection for today s power conversion equipment. This range is a fast acting, engineered to provide state of the art protection for power semiconductors in drives. These solid blades 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 bound sand which provides optimized I t and high breaking capacity. All contact surfaces are silver plated and all hardware non-magnetic. These products comply with the RoHS European Directive. All fuses are standard with a low voltage dual blown fuse indicator. This indicator can operate a microswitch which is easily mounted directly on to the fuse in service. The first gs-class range in the marketplace! Features/Benefits Broad range of ampere ratings in each body size for design flexibility IEC 69-4 compliance for fuses for worldwide semiconductor applications Ratings AC: up to 6 A - 6 VAC - ka IR DC: up to 0 V L/R 0ms for high di/dt (capacitor discharges), consult us Approvals AC: Tested to IEC 69.4 at 6V +0% UL/CSA recognized pending Features Ultra fast acting Highly current limiting. High breaking capacities Very low I t Reduced power losses No derating in standard NH fusegear (ref. to page 9) Worldwide mounting acceptance. Superior cycling ability. High widstanding in rush current and overloads Applications Protection of rectifiers, inverters, static switch, AC & DC drives and UPS systems. Innovations The first gs-class range in the market FERRAZ SHAWMUT IS NOW
