- Product Description
-
First, with reclosing design, in line with the operation timing of the national network breaker, in line with the requirements of "GB1984-2014 high voltage AC circuit breaker"
Second, energy storage, closing, opening logic, designed with mechanical interlocks to ensure correct operation sequence and prevent misuse.
Third, with mechanical interlocking of the isolating switch to ensure that the "five-proof" operation sequence (including forward and reverse interlocking) is met.
Fourth, optional opening operation hole
5. Reserve passive tripping, counters and other extended component positions, humanized design, convenient for retrofit
Sixth, miniaturized design. 325 wide cabinet can also accommodate
Seven, long-life design, stable and trouble-free closing and closing times ≥10,000 times
