GOST 403-73

ГОСТ 403-73

Electrical apparatus for voltages up to 1000 V. Temperature rise limits of devices parts

Аппараты электрические на напряжение до 1000 В. Допустимые температуры нагрева частей аппаратов

Status: Effective - Supersedes. The limitation of the effectiveness period has been lifted: Protocol No. 4-93 of the IGU dated 10.21.93 (IUS 4-1994)

The standard applies to electrical apparatus for voltage up to 1000 V, designed to work in conditions according to GOST 1515- and GOST 15543, and sets the permissible heating temperatures for parts of the apparatus. The standard also applies to devices that are embedded in switchgears. The standard does not apply to devices intended for use in highly specialized industries (for example, radio measuring, coal and mining).

Стандарт распространяется на аппараты электрические на напряжение до 1000 В, предназначенные для работы в условиях по ГОСТ 1515- и ГОСТ 15543, и устанавливает допустимые температуры нагрева частей аппаратов. Стандарт распространяется и на аппараты, встраиваеые в комплектные распределительные устройства. Стандарт не распространяется на аппараты, предназначенные для применения в узкоспециальных отраслях (например, радиоизмерительная, угольная и горнорудная).
