Low-voltage switchgear and controlgear enclosed equipment - Enclosed switch-disconnectors outside the scope of IEC 60947-3 to provide isolation during repair and maintenance work Ingestion-build-279162 single and double acting for1 Scope This part of IEC 62626 applies to enclosed switches disconnectors with rated voltages up to 1 000 V a. c. for repair and maintenance work or cleaning work in load circuits. Devices within the scope of this standard are derived from switch disconnectors according to IEC 609473. Enclosed switch disconnectors in this standard are suitable for isolation according to IEC 60947 series and are not supposed to be equipped with means for remote control
