1、 Scope of application
DZ30-32 is suitable for protecting electrical circuits from overload and short circuit in single-phase lines with AC 50Hz and 60Hz and rated voltage below 250V. Being able to disconnect both the L and N lines simultaneously is currently the most ideal distribution protection switch in the residential field. This product complies with IEC60898 and GBI0963 standards.
