    High-voltage current -limiting fuse XRNP for high-voltage transformer protection

    I. Overview

    This product is suitable for indoor AC 50Hz, rated voltage 3.6-40.5KV system for overload and short circuit protection of voltage transformer. (Passed the type test of the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center, and the product complies with GB15166.2 and IEC282-1).

    Features

    1. High breaking capacity, breaking current can reach 63KV.
    2. Low power consumption and low heating.
    3. The action is particularly fast. The one second feature is faster than similar products currently produced in China. For example, a fuse with a rated current of 100A can pass an expected current of 1000A and the time before the arc does not exceed 0.1S.
    4. Ampere-second characteristic error is less than ± 10%.
    5. Equipped with a spring-type impactor, which has a large contact surface and a small pressure. Therefore, when the switch interlock operation is pushed, the contact surface between the switch and the striker will not be broken or broken.
    6. Standardization of specifications.
    7, has a greater current limiting effect.
    8, product performance in line with GB15166.2 national standards and IEC60282-1 international standards.
    9. It can reliably break any fault current between the minimum breaking current and the rated breaking current. In addition, various non-standard products can be produced according to user needs.
