Abstract: A method of temperature?rise verification of low?voltage switchgear and con?trolgear assemblies according to IEC/TR 60890 is reaseardzed , based on ABB software OTC ( Over Temperature Calculation) experience gained from projects, which helps de?signers to easily calculate the temperature rise, power consumption and estimate the fan exhaust air volume, and improves the qulity of design and selection of low?voltage eletrical equipment. It has reference significance for low?voltage switchgear and controlgear’ s se?lection.
