Scope

This standard specifies the classification, characteris ics, structural and performance requirements, test methods, inspection rules, marking, packaging, transportation and storage of mine explosion-proof low-voltage AC vacuum feed switches. This standard is suitable for use as a main dis ribution switch or branch feed switch for AC 50Hz, voltage up to 1200V circuits in mines containing gas and coal dust. It is also suitable for feed switches that directly control large-capacity motors that start infrequently.
