適用范圍：This part of IEC 60947 applies to fuse terminal blocks with screw-type or screwless-typeclamping units for the connection of rigid (solid or stranded) or flexible copper conductors forthe 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 thefuse 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 bedesigned exclusively for short-circuit protection.NOTE This standard may be used as a guide for fuse terminal blocks for the reception of special cartridge fuselinkswhich 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 examplequick connect terminations or wrapped connections, etc.;? fuse terminal blocks providing direct contact to the conductors by means of edges or pointspenetrating 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.
