1.1范围IEC 60947的本部分适用于带有螺钉式或无螺钉式夹紧装置的保险丝接线盒，用于连接刚性（实心或绞合）或挠性铜导线，以便按照IEC 60127-2接收盒式熔断器，主要用于工业或类似用途，用于交流电压不超过1000 V、频率不超过1000 Hz或直流电压不超过1500 V的电路。，最大短路分断能力为1500 a。 它们用于安装在电气设备中，电气设备的外壳围绕着保险丝接线盒，其范围应确保只有借助工具才能接近。对于某些应用，例如在控制电路中，保险丝接线盒可专门设计用于短路保护。 注:本标准可用作接收特殊盒式保险丝的保险丝接线盒指南- 不符合IEC 60127-2要求的链路。本标准的目的是规定熔断器端子块的机械、电气和热特性的安全要求和试验方法，以确保端子块和标准化熔断器之间的兼容性。本标准可作为熔断器接线盒的指南，熔断器接线盒需要将特殊装置固定到导体上，例如快速连接终端或缠绕连接等熔断器接线盒通过穿过绝缘层的边缘或点与导体直接接触，例如绝缘位移连接等。在本标准适用的情况下，使用术语“夹紧装置”代替术语“端子”。在参考IEC 60947-1.1.1DV修改时，通过添加以下内容将其考虑在内: 根据附录DVB、国家电气规范、NFPA 70（美国使用）、CSA C22，本标准规定了用于连接刚性（实心或绞合）或挠性铜导线的带螺钉式或无螺钉式夹紧装置的保险丝接线盒的要求。1-15《加拿大电气规范》第一部分（供加拿大使用）和NOM-001-SEDE《电气装置（公用设施）》（供墨西哥使用）。

1.1 ScopeThis part of IEC 60947 applies to fuse terminal blocks with screw-type or screwless-type clamping units for the connection of rigid (solid or stranded) or flexible copper conductors for the reception of cartridge fuse-links in accordance with IEC 60127-2, intended primarily for industrial or similar use in circuits not exceeding 1 000 V a.c., up to 1 000 Hz or 1 500 V d.c., and having a maximum short-circuit breaking capacity of 1 500 A. They are intended for installation in electrical equipment with enclosures which surround the fuse terminal blocks to such an extent that they are accessible only with the aid of a tool.For certain applications, for example in control circuits, the fuse terminal blocks may be designed exclusively for short-circuit protection. NOTE This standard may be used as a guide for fuse terminal blocks for the reception of special cartridge fuse- links which do not meet the requirements of IEC 60127-2.The object of this standard is to specify safety requirements and test methods for the mechanical, electrical and thermal characteristics of fuse terminal' blocks, to ensure the compatibility between terminal blocks and standardized fuse-links.This standard may be used as a guide for- fuse terminal blocks requiring the fixing of special devices to the conductors, for example quick connect terminations or wrapped connections, etc.;- fuse terminal blocks providing direct contact to the conductors by means of edges or points penetrating the insulation, for example insulation displacement connections, etc.Where applicable in this standard, the term "clamping unit" has been used instead of the term "terminal". This is taken into account in case of reference to IEC 60947-1.1.1DV Modification by adding the following:This standard specifies requirements for fuse terminal blocks with screw-type or screwless-type clamping units for the connection of rigid (solid or stranded) or flexible copper conductors for the reception of cartridge fuse-links, in accordance with Annex DVB, National Electrical Code, NFPA 70 (for use in the USA), CSA C22.1 - 15 Canadian Electrical Code, Part I (for use in Canada), and NOM-001-SEDE, Electrical Installations (Utility) [for use in Mexico].
