Scope

This standard applies to the empty housing provided by the housing manufacturer (hereinafter referred to as the housing), which is the product of the user before the installation of switchgear and control gear components. This standard specifies the definition, classification, performance and test requirements for housings used in low-voltage complete switchgear and control equipment that comply with GB 7251 series standards. The rated voltage of the low-voltage switchgear and control equipment is not more than 1000V for AC, 1000Hz for frequency or 1500V for DC, suitable for indoor or outdoor use. This standard does not apply to housings mentioned in other specific product standards (such as IEC 60670). The final turnkey equipment manufacturer is responsible for the safety requirements of the corresponding product standards.
