A vacuum circuit breaker contact system comprises an installation base seat (a). Vacuum arc-extinguishing chambers (b) are disposed in a plurality of cavities (a01) of the installation base seat (a). The vacuum circuit breaker contact system is characterized in that movable ends (b01) of the vacuum arc-extinguishing chambers (b) of the cavities (a01) of the installation base seat (a) and static ends (b02) of the vacuum arc-extinguishing chambers (b) in the adjacent cavities are arranged side by side. An installation structure of the vacuum arc-extinguishing chamber is changed, effective space of arc diffusion is increased and a center distance of adjacent movable and static contacts is increased, so breaking reliability and stability can be enhanced; and product cost can be reduced and product volume can be lowered. 种真空断路器接触系统，它包括安装基座(a)，所述安装基座(a)的若干空腔(a01)内都安装有真空灭弧室(b)，其特征在于：所述安装基座(a)空腔(a01)内的真空灭弧室(b)的动端(b01)与相邻空腔内真空灭弧室(b)的静端(b02)并列排布；本发明将真空灭弧室安装结构进行改变，增加电弧扩散的有效空间，增加相邻动静触头中心距离，提高了分断的可靠性和稳定性。降低了产品成本，减小了产品的体积。
