China High Quality Fuse Monitoring Devices Supplier – Fuse monitoring devices – Mersen Detail:
This series of Fuse monitoring devices are used in electric lines of 50Hz AC and rated voltage up to 1000V as melting signal / siren for the fuse links.
It is made up of the following parts:1. Melt striker, 2. Micro switch (with one normal close contact and one normal open contact), 3. A base for the striker and the switch. Fuse monitoring devices are usually paralleled under the lid fastening screws at the ends of the fuse. When the fuse breaks, the striking pin springs out of the striker, the microswitch pushed and signal sent out or circuit cut down. Then distance between the two fastening ends can be adjusted in a certain range for paralleling to fuses with different heights.
Models, rated voltage,and dimensions are shown in Figures 13.1~13.2 and Table 13.
This series of fuses are suitable for lines with rated DC voltage up to 1500V and rated current up to 50A. They are connected in series and parallel with photovoltaic panels and batteries to provide short-circiut protection for the charging and converter system; at the same time, for photovoltaic power plants, the confluence inverter short-circuit fault breaking protection; and for photovotaic power generation system surge current and short-circuit fault over-voltage rapid breaking protection, rated breaking capacity up to 50kA, the product meets the requiremnets of the international electrotechnical commission standard IEC60269-6 and UL248-19.
① Double cover design with inner cover and outer cover.
② The thickness of the electroplated coating is thickened, which promotes the contact between the inner cover and the conductive part of the base more closely and the conductivity is better.
③ The fused piece is made of pure silver, which ensures that the product has low temperature rise, low power consumption, long service life, overload or short circuit can play the best protection role.
④We have designed a more perfect solution, which can make the rated current of 10 * 85 reach 35A and the breaking capacity reaches 50kA. It completely meets the requirements of current promotion of
solar crystalline silicon panel in the market, and enables users to reduce the cost utilization rate higher without changing the solution of combiner box.
⑤ UL, TUV certification
