BS EN IEC 60947-7-1:2025

This standard BS EN IEC 60947-7-1:2025 Low-voltage switchgear and controlgear is classified in these ICS categories:

• 29.130.20 Low voltage switchgear and controlgear

IEC 60947-7-1:2025 specifies requirements for terminal blocks and test disconnect terminal blocks according to Annex D with screw-type or screw-less-type clamping units primarily intended for industrial or similar use and to be fixed to a support to provide electrical and mechanical connection between copper conductors. It applies to terminal blocks intended to connect round copper conductors, with or without special preparation, having a cross-section between 0,05 mm2/30 AWG and 300 mm2/600 kcmil, intended to be used in circuits of a rated voltage not exceeding 1 000 V AC up to 1 000 Hz or 1 500 V DC. The tests on terminal blocks are made with AC or DC supply as required in relevant clauses of this document. This fourth edition cancels and replaces the third edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Scope extension for smaller conductor cross-sections; b) Implementation of a contact pressure via insulation material (CoPI) test; c) Introduction of new informative Annex E for larger cross-sections; d) Reorganisation of all tables merged into two tables for electrical and mechanical values; e) Implementation of AWG-sizes conductor types as an equivalent type of metric conductor with examples in Annex C; f) Reorganisation of Annex D test disconnect terminal blocks to enhance readability; g) Introduction of new informative Annex A for main characteristics of terminal blocks.
