2017年10月3日 · Generator circuit-breaker (GCB) type HEC 10 is the latest addition to ABB’s GCB portfolio to increase protection in large power plant units. A high-performing GCB backed by two decades of successful field experience, HEC 10 is developed to satisfy the most demanding safety requirements in large power plants up to 1,500 MW.

Based on the well-proven and highly reliable VD4 platform with over 1,000,000 installations since 1986, the VD4G product family is tested to meet the most stringent IEEE and IEC requirements for generator applications as per IEEE C37.013 and the new revision IEC/IEEE 62271-37-013, the only standards for GCB.
