    Abstract - (Show below) - (Hide below)

    Specifies all-or-nothing relays that have contacts in their output circuits (the term includes relays with specified time, but not measuring relays). Includes definitions of more than 90 terms, specifies standard values for parameters and influence quantities, and covers performance in terms of accuracy, temperature rise, mechanical durability and contact life. Appendices explain the concepts and provide guidance.
