1.The product is suitable for indoor switchgears with a rated voltage of 40.5kv and 50~60Hz 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 40.5kv series vacuum breaker can either be used as fixed type or handcart type.
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 conform with the relevant requirements fo IEC62271-100.
