The following circuit diagram The current fuse in position F1 is usually connected in series with the line.The photos of the real thing are shown in the following two pictures, the left one is not labeled, the right one shows the location of the current fuse and some other basic information. In the diagram above,…
working votlage: maximum voltage to which the part under consideration is subjected when the appliance is supplied at its rated voltage and operating under normal operation, with controls and switching devices positioned so as to maximize the value NOTE 1 working voltage takes into account resonant voltages. NOTE 2 When deducing the working voltage, the…
There is a note in table 17 and table 18 as “For working voltages > 10 V and ≤ 630 V, if the voltage is not specified in the table, the values of creepage distances may be found by interpolation.”. If the operating voltage is not the value listed in the table, then we usually…
