IEC 61810-10:2019, with functional and safety aspects, applies to electromechanical elementary relays (non-specified time all-or-nothing relays) with high capability requirements like breaking or short circuit capabilities and similar for incorporation into low-voltage equipment. These relays may have a specific design to extinguish the electric arc between contacts (e.g. by magnetic blow-out), or use an insulation coordination not covered by IEC 61810-1 (e.g. by gas filled contact chambers), or require safety assessments not covered by IEC 61810-1 (e.g. for higher loads). It defines additional requirements for high-capacity relays with generic performance intended for use in applications in smart grids, electric vehicles and other applications where, for example, battery charge/discharge switching is used, such as: • electrical energy storage (EES) systems, • solar photovoltaic energy systems, • electric road vehicles (EV) and electric industrial trucks, • power electronic systems and equipment, • secondary cells and batteries, • road vehicles. Compliance with the requirements of this standard is verified by the type tests indicated.

本文件规定了直流系统用剩余电流动作继电器(以下简称“DC-RCR”)的术语、定义、分类、特性、标志、其他产品资料、使用的标准工作条件、结构、动作要求和试验。 本文件适用于额定电压不超过直流750V的直流配电线路中进行直流剩余电流检测的DC-RCR。DC-RCR用于低压直流设备(系统)中剩余电流监测,当带电部件与外露导电部件或地之间的剩余电流超过预定值时发出报警信号输出。DC-RCR通常不与被监视回路直接相连接,但用于额定电流不超过250A的直流系统的剩余电流监视。 注:额定电压高于750V但不超过直流1500V的直流剩余电流动作继电器参照本文件进行试验。 本文件给出了DC-RCR预期在污染等级为3的环境中使用的要求,超出此约束需提供其他防护措施。 本文件不适用于直接作为保护装置使用,但DC-RCR与其它开关电器配合并符合相关保护安全要求时,用于控制开关电器对系统及设备提供接地故障及对人身电击危险提供间接接触保护。同时也不适用于具有内部电池的剩余电流监测装置。
