1. Overview
This product is suitable for indoor AC 50Hz, rated voltage 3.6-40.5KV system as overload and short circuit protection for voltage transformers. (Passed the type test of the National High Voltage Electrical Quality Supervision and Inspection Center, and the product complies with GB15166.2 and IEC282-1).
2. Features
1. High breaking capacity, and the breaking current can reach 63KV.
2. Small power consumption and low temperature increase.
3. The action is particularly fast. The 1-second characteristic is faster than similar products currently produced in China. For example, the fuse body with a rated current of 100A is connected to the expected current of 1000A, and the time before arcing does not exceed 0.1S.
4. The 1-second characteristic error is less than ±10%.
5. It is equipped with a spring-type impactor, which has a large contact surface and a small pressure. Therefore, when pushing the switch link lock action, there will be no situation of breaking or breaking down the contact surface of the switch and the striker.
6. Standardization of specifications.
7. It has a large current limiting effect.
8. The product performance complies with the national standard of GB15166.2 and IEC60282-1.
9. Any fault current between the minimum breaking current and the rated breaking current can be reliably cut off. In addition, various non-standard products can be produced according to user needs.
