简要说明：MINRONG/民熔牌的民熔电气厂家直销RN1-10/2-400A熔断器产品：估价：28，规格：RN1-10/2-400，产品系列编号：齐全

　　

RN1型户内高压限流熔断器，用于电力线路的过载及短路保护。所谓限流就是熔断器在短路电流达到峰值之前就将其切断的功能。 □The product is in overload or short-circuit protection for elctric transformer. The current limiting means that the fuse will cut off the circuit before the shortcircuit current reaches the peak value. ◆熔断特性 当通过熔断器的电流为其额定电流的1.3倍时，1小时不熔断；当通过熔断器的电流为其额定电流的2倍时，1小时内熔断；熔断器的熔断特性曲线如图1，供选择熔断器时参考。 Current which passes the fuse when being 1.3 times of its specified electric current, Do not fusing for an hour; When the current through the fuse is 2 times of its specined electric current, fusing in an hour; Refer to its fusing feature curve in chart 1 when select the fuse.   ◆熔断管结构Structure of fuse link 熔断管是熔断器的主要部件，它是由熔丝装在瓷管中，并在瓷管中充填石英砂，两端密封而成。额定电流在7.5A以下及额定电压 为35V的熔管，其熔丝是绕在特制的瓷芯上，如图2.a；额定电流在7.5A以上的熔体管，其熔丝是悬挂在瓷管中如图2.b。 The fuse pipe is the main part of fuse,it is made by installing the fuse wire in the porcelain pipe,filling the quartz sand in the porcelain pipe and sealing to-ends of pipe.For the fuse pipe with rated current below 7.5Aand 35V rated voltage,its fuse wire is rolled on the special por- celain core,referening to chart 2.a.for the fuse pipe with rated current above 7.5A,its fuse wire is hang in the
