PD IEC/TR 61912-1 is a technical report, which serves as an application guide for the short-circuit ratings given in IEC standards for low-voltage switchgear and controlgear and assemblies.
PD IEC/TR 61912-1 summarises the definitions of the ratings and provides examples of their application. Low-voltage equipment standards IEC 60947 and IEC 60439 currently include short-circuit ratings for products and assemblies respectively.
PD IEC/TR 61912-1 on low-voltage switchgear and controlgear is helpful for:
Having access to reliable guidelines is essential to prepare and use quality low-voltage switchgear and controlgear. PD IEC/TR 61912-1 provides manufacturers with the principle of application and installation, the characteristics of low-voltage assemblies and the characteristics of switching devices which allows them to manufacture and test low-voltage switchgear and controlgear effectively.
PD IEC/TR 61912-1 provides the users with efficient and standardized low-voltage switchgear and controlgear.
