WebPrimary Fuses Introduction The wide variety of fuse links offered by the A.B. Chance Company is instrumental in reducing the many problems facing today’s coordination engineers. Besides the increasingly popular ANSI K and T fuse links, there is available a series of precision engineered fuse links designed especially for transformer protec-tion. WebSUMMARY. Selective coordination strategies are used to minimize the number of loads that will be de-energized if a fuse or breaker opens. These strategies enable overcurrent protection devices nearest to faults to trip first, avoiding power disruption to a greater amount of load equipment. Selective coordination is accomplished by using ...
