    Abstract - (Show below) - (Hide below)

    Specifies requirements for flameproof supply and control units meant primarily for use in the coal mining industry on 1100 V three-phase a.c. circuits and dual-voltage 1100 V/550 V units with circuit breakers for the protection and control of power circuits. Coverage includes rated values, definitions, service conditions, marking, and design and construction. Also gives detailed diagrams.
