小型熔断器.第8部分:带过电流保护的熔断电阻器

[中文适用范围]： IEC 60127 的这一部分涉及具有特定过流保护的熔断电阻器，额定值高达 AC 500 V 和/或 DC 500 V，用于印刷电路和其他基板系统，用于保护电器、电子设备及其零部件，通常用于保护用于室内。它不适用于在特殊条件下使用的具有特殊过流保护的熔断电阻器，例如在腐蚀性或爆炸性环境中。 IEC 60127 本部分的目的是 a) 对具有特定过流保护功能的熔断电阻器建立统一的要求，以便以最合适的方式保护电器或电器部件； b) 规定了具有特定过流保护功能的熔断电阻器的性能，以便为电器和电子设备制造商提供指导，并确保具有相似尺寸和特性的熔断电阻器能够替代具有特定过流保护功能的熔断电阻器； c) 对具有特定过流保护功能的熔断电阻器建立统一的测试方法，以便验证制造商规定的值（例如额定耗散、功能特性和额定分断能力值）。具有特定过流保护功能的熔断电阻器的制造商应自行负责确保其产品符合电阻器相关标准 IEC 60115-1、IEC 60115-4-101 和 IEC 60115-4-1021 的要求。除 IEC 60127-1 的要求外，IEC 60127 的本部分也适用。 [外文原描述]： IEC 60127-8:2018 relates to fuse resistors with particular overcurrent protection rated up to AC 500 V and/or DC 500 V for printed circuits and other substrate systems, used for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to be used indoors. It does not apply to fuse resistors with particular overcurrent protection for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere. The object of this part of IEC 60127 is a) to establish uniform requirements for fuse resistors with particular overcurrent protection so as to protect appliances or parts of appliances in the most suitable way; b) to define the performance of the fuse resistors with particular overcurrent protection, so as to give guidance to manufacturers of electrical appliances and electronic equipment and to ensure replacement of fuse resistors with particular overcurrent protection by those of similar dimensions and characteristics; c) to establish uniform test methods for fuse resistors with particular overcurrent protection, so as to allow verification of the values (for example rated dissipation, functioning characteristic and rated breaking capacity values) specified by the manufacturer. This part of IEC 60127 applies in addition to the requirements of IEC 60127-1. This first edition of IEC 60127-8 cancels and replaces IEC PAS 60127-8:2014. This international standard is to be used in conjunction with IEC 60127-1. Keywords: Miniature Fuses, Fuse-Resistors, Overcurrent Protection
