The scope of EN 61008-1 and EN 61008-2-1 or EN 61009-1 and EN 61009-2-1 applies with the following additions.
This standard specifies requirements and tests for Type F and Type B RCDs (Residual current devices). Requirements and tests given in this standard are in addition to the requirements of Type A residual current devices according to EN 61008-2-1 or EN 61009-2-1. This standard can only be used together with EN 61008-1 and EN 61009-1.
Type F RCCBs (Residual Current Circuit Breaker) and Type F RCBOs (Residual current Circuit Breaker with Overcurrent protection) are intended for installations when frequency inverters are supplied between phase and neutral or phase and earthed middle conductor and are able to provide protection in case of alternating residual sinusoidal at the rated frequency, pulsating direct residual currents and composite residual currents that may occur.
Type B RCCBs and Type B RCBOs are able to provide protection in case of alternating residual sinusoidal currents up to 1 000 Hz, pulsating direct residual currents and smooth direct residual currents.
Type F and type B RCDs have high resistance against unwanted tripping even if the surge voltage causes a flashover and a follow-on current occurs and in case of inrush residual currents with a maximum duration of 10 ms which can occur in case of switching ON electronic equipment or EMC-filters.
RCDs according to this standard are not intended to be used in d.c. supply systems.
Further requirements and tests for products to be used in situations where the residual current was not intended to be covered in EN 61008-1 or EN 61009-1 are under consideration.
The complete test sequence for type test of Type F RCCBs and Type F RCBOs is given in Tables A.1 and B.1 respectively. The complete test sequence for type test of Type B RCCBs and Type B RCBOs is given in Tables C.1 or D.1 respectively.
NOTE 1 Throughout the document, the term RCD refers to RCCBs and RCBOs.
NOTE 2 Deleted.
NOTA 3 *
* N.d.R. Il testo della Nota 3 della Norma IEC è recepito come parte integrante della Norma da parte del CENELEC pur non essendo la modifica segnalata nell’elenco delle Modifiche Comuni. Per questo motivo la Nota 3 IEC è stata eliminata.
