Type of circuit breaker for the three-level distribution box
As for the equipment inside, there are certain differences: the first level distribution cabinet generally has isolation switches, circuit breakers, leakage protectors, etc., the second level contains a large three-phase circuit breaker, and the third level . The 3VA molded case circuit breaker with certification in accordance with the American standard UL489 (3VA UL) is a well thought-out, modular and highly variable system that is rigorously designed to provide optimum support in every process step – from engineering to daily operation of the. In a newly constructed residential area, a 10kV power line is introduced into the substation. After stepping down the voltage through the transformer's low-voltage side (0. 4kV), power distribution is achieved through three levels of distribution boxes: the main distribution board, secondary. Circuit breakers are classified by voltage level (low, medium, high), arc-quenching medium (air, vacuum, SF6, oil), application (residential, commercial, industrial), and trip characteristics (Type A, B, C, D).
