Overview

This part of the IEC 60947 series of standards specifies requirements for terminal blocks with screw-type or screwless type clamping units primarily intended for industrial or similar use and to be fixed to a support to provide electrical and mechanical connection. This document can be used for terminal blocks for connection between aluminium conductors or aluminium to copper conductors. It applies to terminal blocks intended to connect round conductors, with or without special preparation, having a cross-section between 2,5 mm² and 300 mm² (AWG 12 to 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. This document does not apply to terminal blocks: - intended for other types of switchgear; - for connections made by crimping, brazing, soldering, or welding; - for data and signaling circuits; - for flat plug connectors, insulation piercing connecting devices, and rotary terminals, for which separate parts are considered. Typical applications for this document include terminal blocks for connecting aluminum conductors or aluminum and copper conductors. It applies to terminal blocks intended to connect round conductors, with or without special preparation, having a cross-section between 2,5 mm² and 300 mm² (AWG 12 to 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. This document can also be used as a guide to qualify other types of terminal blocks for conductors out of aluminium other than feed through terminal blocks (for example, partially insulated terminal blocks).
