Characteristics of New Type High Voltage Current Limiting Fuse
The high-voltage current-limiting fuse produced by our company is a high-quality product with world advanced level on the basis of synthesizing similar products at home and abroad. The product has the following characteristics:
1. The breaker has high capacity, and the breaking current can reach 63 kA.
2. Low power consumption and low temperature rise.
3. The action characteristic is fast, and the one-second action characteristic is faster than that of the similar products produced at present in China. For example, the rated current of 100A powder breaker is 1000A expected current, and the pre-arc time is not more than 0.1S.
4. The characteristic error per ampere is less than 10%.
5. Equipped with spring impactor, the impactor has the advantages of large contact surface and low pressure. Therefore, when the interlocking action of the switch is pushed, the breakdown or breakdown of the contact surface between the switch and the impact needle will not occur.
6. Standardization of specifications.
7. It has great current limiting effect.
8. The product performance conforms to GB/T15166.2 and IEC60282-1 international standards.
9. Can reliably interrupt any barrier current between minimum interruption current and rated interruption current. In addition, it can also produce various kinds of non-standard products according to the needs of users.
Instructions for Order
