1. The product is suitable for indoor switchgears with a rated voltage of 12kv and 50Hz three-phase current as the control and protection unit for high voltage electrical equipment.
2. The module spring operating mechanism is used for the breaker. Simple, mature, robust and convenient, the mechanism strengthen the reliability of circuit breaker's performance, and allows frequent operations or multiple breaks of the short-circuit current within the range of the operating current.
3. The 12kv series vacuum breaker can either be used separately or used for the metal-clad withdrawal switchgear and fixed switchboard and oil-free reforming, and can be interchangeable with similar product abroad.
4.the products have met the requirements of GB1984-2003 AC high-voltage breaker, JB3855-1996 3.6-40.5lv indoor AC high-voltage vacuum breaker and DL403-1999 technical conditions for ordering of 10-35kv indoor high-voltage vacuum breaker, and conform with the relevant requirements of IEC62271-100.
