CD10 series DC electromagnetic operating mechanismDetailed product description：

The technical performance of the CD10 series DC electromagnetic actuator complies with the requirements of the IEC 56 publication "High Voltage AC Circuit Breakers" and GB1984-89 "AC High Voltage Circuit Breakers" standards. The main technical parameters are shown in Table 1.
Note: (1) The opening and closing coils of the mechanism are designed for short-term power on, and the coils are made of QZ-2 high-strength enameled wire.
(2) The negative value in the table refers to the value of+20 ℃.
(3) Equipped with SN10-10I for 6K slot, the minimum closing operation voltage is 85% of the rated voltage.
