GC8-630A tension-spring type flat contact (35 kV)

The GC8-630A tension-spring-type flat contact (35 kV) has been independently developed and successfully manufactured on the basis of digesting and absorbing ABB’s product technologies, achieving complete domestic production and fully replacing imported counterparts. It is widely used in handcart-type circuit breakers such as the ZN63 (VS1, VB1). Its performance complies with the requirements of GB 3906-1991 “AC Metal-Enclosed Switchgear for 3–35 kV.”
