Low-voltage switchgear and controlgear enclosed equipment - Part 1: Enclosed switch-disconnectors outside the scope of IEC 60947-3 to provide isolation during repair and maintenance work (IEC 62626-1:2014); German version EN 62626-1:2014
Gekapselte Niederspannungsschaltgeräte - Teil 1: Gekapselte Lasttrennschalter außerhalb des Anwendungsbereiches von IEC 60947-3, zum Trennen während der Reparatur- und Wartungsarbeit (IEC 62626-1:2014); Deutsche Fassung EN 62626-1:2014
Overview
This standard 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 described in this standard are derived from switch-disconnectors according to IEC 60947-3 and suitable for isolation according to IEC 60947 series. They 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. Furthermore, they are not supposed to be used as a device for emergency stop device. However, this kind of device can provide the possibility to switch off electrical equipment (even in a critical situation or not). Devices described in this standard ensure isolation of electrical equipment, especially in motor circuits, during repair and maintenance or cleaning works. The responsible committee is DKE/K 431 "Niederspannungsschaltgeräte und -kombinationen" ("Low-voltage switchgear and controlgear assemblies") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
