Abstract

本实用新型涉及一种塑壳断路器，具体涉及一种用于塑壳断路器的附件装置及一种塑壳断路器，包括附件面盖和附件支座；附件支座包括仓室、第一安装孔和第二安装孔；仓室为顶底开口的贯通结构，内部设有限位台阶；附件面盖完全覆盖附件支座的开口，且还设有安装孔，附件面盖通过螺纹件依次穿过安装孔和第一安装孔并螺纹锁定实现与附件支座之间的装配；附件支座通过螺纹件穿过第二安装孔并螺纹锁定实现与塑壳断路器壳体之间的装配。与现有技术相比，本解决现有技术中附件的装配会影响塑壳断路器的结构设计，且通用性、可更换性差的情况。本方案的附件装置拥有独立的附件支座，可在不同的附件使用情况下，选择合适的安装形式，具有较好的通用性。
