IEC61008-1 and 61009-1 provide appropri ate requ

However, the use of new electronic technologyin equipment may resultin particular residual currentsnot covered in IEC 61008-1 orIEC61009-1. This standard covers specificapplications where additional requirements andtesting are needed.

41、This standard includes definitions, additional requirements and tests for Type F and Type BRCCBs and/or RCBOs to cover particular situations. The tests shall first be applied according to IEC 61008-1 forType F or Type B RCCBs andaccording to IEC 61009-1 for Type F or Type BRCBOs. After completion of

42、 the te sts given either in IEC 61008-1or IEC 61009-1 the additional testsgiven in this standard shall be applied in order to show conformityto this standard (seeAnnex A, Annex B forTypeFor Annex C, Annex Dfor Type Brespectively).The number of samples to be submittedand test sequences to beapplied f

Type F RCDs

In case ofa frequency inverter, e.g. used for motorspeed control, supplied between phase andneutral,a composite residual current including the pow

This standard introduces Type B RCDs to be used in case ofresidual pulsating rectified direct currentwhich results from one or more phases
