What is BS EN 60947-7-3 - Safety requirements for fuse terminal blocks about?

BS EN 60947-7 is a European standard on Low-voltage switchgear and controlgear - Ancillary equipment. BS EN 60947-7-3 is a third part of the multi-series standard that specifies the safety requirements for fuse terminal blocks. BS EN 60947-7-3 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 , 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. For certain applications, for example in control circuits, the fuse terminal blocks may be designed exclusively for short-circuit protection. BS EN 60947-7-3 specifies 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. BS EN 60947-7-3 used as a guide for:
