摘要
介绍了熔断体的保护特性、过电流选择性和截流特性,指出厂RT30与RT14两种熔断体的区别及其适用场合,并由此指出了HG30熔断器式隔离器与HH30开关熔断器组的区别及其适用场合.
The protective characteristic, over-current discrimination and cut-off current characteristic of fuse-link is introduced. The difference between RT30 and RT14 fuse-links and their applicable occasions are pointed out, and from this, the difference between HG30 fuse-disconnector and HH30 switch-fuse and their applicable occasions are also presented.
