小型熔断器.第7部分:特殊应用的小型熔断器

[中文适用范围]： IEC 60127 的这一部分涵盖了特殊应用的微型熔断体的要求。它不适用于 IEC 60269-1 后续部分完全涵盖的熔断器。它不适用于在特殊条件下使用的器具的微型熔断器，例如在腐蚀性或爆炸性环境中。除 IEC 60127-1 的要求外，本标准也适用。本标准适用于额定电压不超过1000V、额定电流不超过20A、额定分断能力不超过50kA的熔断体。用于特殊应用的微型熔断体不适合由电气/电子设备的最终用户更换。本标准的目的是为特殊应用的微型熔断体建立统一的测试方法，以便验证制造商规定的值（例如熔化时间和分断能力值）。 [外文原描述]： IEC 60127-7:2013 covers requirements for miniature fuse-links for special applications. It does not apply to fuses completely covered by the subsequent parts of IEC 60269-1. It does not apply to miniature fuse-links for appliances intended to be used under special conditions, such as in corrosive or explosive atmospheres. This standard applies in addition to the requirements of IEC 60127-1. This standard is applicable to fuse-links with a rated voltage not exceeding 1000 V, a rated current not exceeding 20 A and a rated breaking capacity not exceeding 50 kA. Miniature fuse-links for special applications are not intended to be replaced by the end-user of an electrical/electronic appliance. The object of this standard is to establish uniform test methods for miniature fuse-links for special applications, so as to allow verification of the values (for example melting time and breaking capacity values) specified by the manufacturer.
