           Product Description

          Model:CT19B
          Product Name: CT19B spring operating mechanism
          Product Description:

          This product can operate ZN28 indoor HV vacuum breakers that fixed on boxes and other kinds of HV breakers which have the equal switching work. It has functions of over current protection and under-voltage releasing protection. The mechanical life is 20000 times. Due to the narrow width only 330 mm, it not only increases the stability of the mEchanism, but also makes it more suitable for no-oil reform. (output angle of this mechanism is from 50 °to 55 °) Technical parameters: Specifications of CT19B and data of critical pieces, to see table 1:
