Overview
This product is suitable for indoor AC 50Hz, rated voltage 3.6-40.5KV system as overload and short-circuit protection of voltage transformers. This fuse has a large cutting capacity and can also be used to protect the road separated by the power system. , when the line short-circuit current reaches the value, the fuse will cut off the line, so it is a recommended appliance to protect the power equipment from damage. (Passed the type test of the National High-voltage Electrical Appliance Quality Supervision and Testing Center, and the product complies with GB15166.2 and IEC282-1).
Features
1. High breaking capacity, breaking current up to 63KV.
2. Low power consumption and low temperature rise.
3. The action is very fast, and the one-second characteristic is faster than that of similar products currently produced in China. For example, a fuse link with a rated current of 100A is connected to an expected current of 1000A, and the pre-arc time does not exceed 0.1S.
4. The amp-second characteristic error is less than ±10%.
5. Equipped with a spring-type impactor, the impactor has the advantages of large contact surface and low pressure. Therefore, when the switch is pushed for interlocking action, the contact surface between the switch and the striker will not be broken or broken.
6. Standardization of specifications.
7. It has a larger current limiting effect.
8. Product performance conforms to GB15166.2 national standard and IEC60282-1 international standard.
9. It can reliably break any fault current between the small breaking current and the rated breaking current. In addition, various non-standard products can also be produced according to user needs.
Instructions for use
