| Abstract: | F- C vacuum contactor have been More and more Applied in Electric motor protection below 1200 KW , however, the protection setting and the unsuitability of protection will cause misjudgment. It will Seriously impacted on the reliability and Utility of the equipment. This article introduces characteristics of the F - C vacuum contactor, method of calculating protection setting, choice of the limiting current fuse. In virtue of F - C the curve, mo- tor overload curve and fuse current - second curve, we analyzed the protection coordinate method, which is effective. |
