ISO 10924-5:2016规定了用于道路车辆的额定电压为450 V的断路器。它为这种断路器类型确定了额定电流、试验程序、性能要求和尺寸。 ISO 10924-5:2016旨在与ISO 10924-1和ISO 10924-2结合使用。其条款的编号与ISO 10924-1的编号一致，ISO 10924-1的要求适用，除非根据ISO 10924本部分的特殊要求进行了修改。 ISO 10924-5:2016适用于额定电压为450 V直流电、额定电流不大于300 a、分断容量为6000 a的断路器。

ISO 10924-5:2016 specifies circuit breakers with rated voltage of 450 V for use in road vehicles. It establishes, for this circuit breaker type, the rated current, test procedures, performance requirements and dimensions. ISO 10924-5:2016 is intended to be used in conjunction with ISO 10924？1 and with ISO 10924？2. The numbering of its clauses corresponds to that of ISO 10924？1 whose requirements are applicable, except where modified by requirements particular to this part of ISO 10924. ISO 10924-5:2016 is applicable to circuit breakers with a rated voltage of 450 V d.c., a current rating of no greater than 300 A and a breaking capacity of 6 000 A.
