Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 20641-2006 "Low-voltage switchgear and control equipment shell body General requirements", and
GB/T 20641-2006, compared the main technical changes are as follows.
--- GB 7251 reconstructed reference voltage switchgear and control equipment series of standards;
--- According to the latest standards choreography during the test.
This standard uses the translation method identical with IEC 62208.2011 "Low-voltage switchgear and control equipment generally shell body
begging".
Correspondence between the consistency of the standards of international documents and normative references of the following documents.

Low-voltage switchgear and control equipment
General requirements for shell body
1 Scope
This standard applies to housing provided by the manufacturer, before users install switchgear and control equipment components shell body (hereinafter referred to as
case).
This standard specifies the low-voltage switchgear and control equipment (such as compliance with IEC 61439 series) used in the definition of housing, classification,
Performance and test requirements. Rated voltage not exceeding 1000V AC or DC does not exceed 1500V, for indoor or outdoor applications.
Note 1. The special application can be additional requirements.
Note 2. The United States of America (USA) in accordance with NEMA250 identified with the shell "type." NEMA Enclosure Type identification requirements such as corrosion, rust, icing, oil, and cold
Additional environmental requirements under cold conditions. For this reason, IEC enclosure housing type and class code IP code applies to these markets.
This standard does not apply to other specific product standards and housing (such as the IEC 60670 series) mentioned.
Equipment manufacturer is responsible for the corresponding product standard safety requirements.
Note 3. This standard can be used as basis for the use of standards in other technical committees.
