BS IEC 62873-3-1:2016

Residual current operated circuit-breakers for household and similar use. Particular requirements for RCDs with screwless-type terminals for external copper conductors | Status: Superseded, Withdrawn

1 Scope This part of IEC 62873 applies to RCDs equipped with screwless terminals, for current not exceeding 20 A primarily suitable for connecting unprepared (see 3.5) copper conductors of cross-section up to 4 mm2. This part of IEC 62873 cannot be used alone but it is intended to be applied together with an RCD product standard (IEC 61008‑1 or IEC 61009‑1) if an RCD is equipped with screwless terminals.

NOTE In AT, CZ, DK, NL, NO, PO, PT and CH, the upper limit of current for use of screwless terminals is 16 A.

In this part of IEC 62873, screwless terminals are referred to as terminals and copper conductors are referred to as conductors.
