NEN-EN-IEC 62626-1 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 60947-3. 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 or automatic switching to avoid unexpected or accidental start. These devices are not intended to be used for operational switching, quick start and stop or jogging. Devices within the scope of this standard provide isolation of electrical equipment, especially in motor circuits, during repair and maintenance or cleaning works. Enclosed switch-disconnectors for various applications to provide isolation of electrical equipment during repair and maintenance work, named “maintenance switches”, are designated hereafter as devices with: a) different classes; b) characteristics of each class; c) minimum test requirements; d) information to be marked on the equipment or made available by the manufacturer, for example in the catalogue.
