Scope
Scope: This document specifies the terms, definitions, classification, characteristics, marking, other product information, standard working conditions, structure, action requirements, and testing for residual current operated relays (hereinafter referred to as "DC-RCR") used in DC systems. This document applies to DC-RCRs used for DC residual current detection in DC distribution lines with a rated voltage not exceeding 750V. DC-RCRs are used for residual current monitoring in low-voltage DC equipment (systems), and issue an alarm signal when the residual current between live components and exposed conductive parts or ground exceeds a predefined value. DC-RCRs are typically not directly connected to the monitored circuits, but are used for residual current monitoring in DC systems with a rated current not exceeding 250A. Note: DC-RCRs with a rated voltage higher than 750V but not exceeding 1500V are tested in accordance with this document. This document specifies the requirements for DC-RCRs intended for use in environments with a pollution level of 3, and additional protective measures are required if these constraints are exceeded. This document does not apply to DC-RCRs used directly as protection devices, but when DC-RCRs are used in conjunction with other switching devices and comply with relevant protection safety requirements, they are used to control switching devices to provide ground fault protection for systems and equipment and indirect contact protection against electric shock hazards. It also does not apply to residual current monitoring devices with internal batteries. Main technical content: This document specifies the terms, definitions, classification, characteristics, marking, other product information, standard working conditions, structure, action requirements, and testing for residual current operated relays (hereinafter referred to as "DC-RCR") used in DC systems. This document applies to DC-RCRs used for DC residual current det
