New type of high pressure current limiting fuse product features

　The high-pressure current limiting fuse produced by our company is a high-quality product with world-class quality, developed on the basis of comprehensive research of similar products at home and abroad. The product has the following features:

✩High-capacity circuit breaker, rated for up to 63KA of interrupting current;

✩Low power consumption; low temperature rise;

✩Action characteristics are fast, and the action of one second characteristics is faster than the same kind of products produced in China at present, for example, the rated current 100A fuse, the arc time is not more than 0.1S when the expected current of 1000A is passed through

✩Less than  ±10% error in the characteristic of pressing according to the first method;

✩Equipped with a spring-type striker, which has the advantages of large contact surface and low pressure. Therefore, when pushing the switch interlocking action, will be no case of shattering or perforating the contact surface of the switch and the striker.

✩Specification standardization

✩Has a significant limiting effect;

✩Capable of reliably breaking any fault current between the minimum breaking current and the rated breaking current. In addition, various non-standard products can be produced according to the's requirements.
