scope:
This document applies to devices equipped with screwless-type terminals for current not exceeding 40 A, primarily suitable for connecting unprepared copper conductors of cross-section up to 10 mm2.
This document cannot be used alone but is intended to be applied together with the applicable product standard in which it is referred to.
NOTE 1 In CZ, DK, NL, PO and CH, the upper limit of current for use of screwless-type terminals is 16 A.
NOTE 2 In JP, the upper limit of current for use of screwless-type terminals is 30 A.
NOTE 3 The manufacturer can declare in its documentation specific conditions permitting the use of prepared conductors.
In this document, screwless-type terminals are referred to as terminals, and copper conductors are referred to as conductors.
