Yes . 6.6Kv VCB of unearthed system can be used for earthed system. The criteria is the insulation level for which the VCB is manufactured which will be available on the name plate. Also in unearthed system in case of a Phase fault, the voltage between earth and a healthy phase will be root three times more than in case of an earthed system. I can give only these comments woth the available information in the post
