GC5-630A (12 pieces) plum-shaped contacts

The GC5-630A (12-pole) plum-blossom contact has been successfully developed in-house based on the digestion and absorption of ABB’s product technology, achieving complete domestic substitution for 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.”
