    Abstract - (Show below) - (Hide below)

    This revision of ANSI/UL 60947-7-3 dated April 21, 2021 is being issued to update the title page to reflect the most recent designation as a Reaffirmed American National Standard (ANS).

    Scope - (Show below) - (Hide below)

    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.
