This 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.
