Product Description

Product Description

    The overall structure of the product is three-phase common box type, three-phase vacuum arc extinguishing chamber in a metal box, reliable variable voltage performance,high insulation strength. The operating mechanism of this series of products is spring energy storage type, which is divided into electric and manual two kinds. The circuit breaker meets the requirements GB1804 DL403,GB11022 and other standards, whether under normal conditions of use or under fault conditions (especially in the case of short circuit), as long as the number of pole parameters of the circuit breaker are within the range, it can ensure safe and reliable operation in the power grid of the corresponding voltage level.
