| Title | Low-voltage switchgear and controlgear - Part 7-2: Ancillary equipment - Protective conductor terminal blocks for copper conductors |
| Project Number | 21333 |
| Abstract/Scope | IEC 60947-7-2:2009 specifies requirements for protective conductor terminal blocks with PE function up to 120 mm2 (250 kcmil) and for protective conductor terminal blocks with PEN function equal to and above 10 mm2 (AWG 8) with screw-type or screwless-type clamping units, primarily intended for industrial applications. Protective conductor terminal blocks are used to form the electrical and mechanical connection between copper conductors and the fixing support. lt is applicable to protective conductor terminal blocks for the connection of round copper conductors with or without special preparation having a cross-section between 0,2 mm2 and 120 mm2 (AWG 24 and 250 kcmil), intended to be used in circuits of a rated voltage not exceeding 1 000 V a.c. up to 1 000 Hz or 1 500 V d.c., most commonly in conjunction with terminal blocks according to IEC 60947-7-1. This standard may be used as guide for - protective conductor terminal blocks requiring the fixing of special devices to the conductors, for example quick connect terminations or wrapped connections, etc.; - protective conductor 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. The main technical modifications of this standard since this previous publication are listed below: - requirements for tightening torques for the tests improved and referenced to Table 4 of IEC 60947-1, Annex B deleted; - the wording of the short-time withstand current test improved in 8.4.6. This publication shall be read in conjunction with IEC 60947-1:2007 and IEC 60947-7-1:2009. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
