IEC 60947-7-2:2009 specifies requirements for protective conductor terminal blocks with PE function up to 120 mm

2

(250 kcmil) and for protective conductor terminal blocks with PEN function equal to and above 10 mm

2

(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 mm

2

and 120 mm

2

(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
