description The invention relates to a primary and secondary fusion complete-set pole-mounted vacuum circuit breaker which comprises a circuit breaker body and a support, the circuit breaker body comprises a shell internally provided with an operating mechanism, the shell is connected with the support through a plurality of mounting bolts, the bottoms of the two opposite sides of the shell are connected withfixing plates respectively, the support is provided with an installation groove allowing the shell and the fixing plates to extend in at the same time, and the mounting bolts penetrate through the fixing plates and then is in threaded connection with the bottom wall of the installation groove. When the shell and the fixing plates extend into the installation groove, a positioning groove with an opening in the upper end is formed between the side wall of the installation groove and the shell, a baffle used for sealing the opening of a positioning groove is hinged to the support, a retainer usedfor positioning the baffl
