25、ecially motor circuits, during repair, cleaning and maintenance works. Such enclosed switch-disconnectors are sometimes known as “maintenance switches”, or “safety switches”. The name “safety switch” is also used for safety related position switches, inspection switches and switches for other applic
26、ations, which are not covered by this standard. This part of IEC 62626 specifies additional requirements for enclosed switch-disconnectors according to IEC 60947-3 to provide isolation of electrical equipment during repair and maintenance work. Enclosed switch-disconnectors according to this standar
27、d are mounted close to the equipment which has to be isolated and are usually operated by instructed persons. NOTE 1 The term “safety switch” is not recognized in some countries as the same meaning given in this standard. NOTE 2 Switch-disconnectors do not necessarily meet the requirements for preve
28、ntion of unexpected start, especially if there are energy sources other than electrical.

29、enance work 1 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 60947-3. En
30、closed 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,
31、 quick start and stop or jogging. NOTE 1 However, these kind of devices can provide the possibility to switch off electrical equipment (even in a critical situation or not). Devices within the scope of this standard provide isolation of electrical equipment, especially in motor circuits, during repa
32、ir 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
33、; c) minimum test requirements; d) information to be marked on the equipment or made available by the manufacturer, for example in the catalogue. NOTE 2 This standard does not specify additional requirements that are necessary for the application of these switches, for example, in explosive atmosphe
34、res (e.g. ATEX in Europe). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、, the terms and definitions given in IEC 60050-441, IEC 60947-1, IEC 60947-3, as well as the following apply. 3.1 (mechanical) switch mechanical switching device capable of making, carrying and breaking currents under normal circuit conditions which may include specified operating overload condition
38、s and also carrying for a specified time currents under specified abnormal circuit conditions such as those of short-circuit Note 1 to entry: A switch may be capable of making, but not breaking, short-circuit currents. SOURCE: IEC 60050-441:1984, 441-14-10 3.2 disconnector mechanical switching devic
39、e which, in the open position, complies with the requirements specified for the isolating function Note 1 to entry: A disconnector is capable of opening and closing a circuit when either a negligible current is broken or made, or when no significant change in the voltage across the terminals of each
40、 of the poles of the disconnector occurs. It is also capable of carrying currents under normal circuit conditions and carrying for a specified time currents under abnormal conditions such as those of short circuit. SOURCE: IEC 60050-441:1984, 441-14-05, modified Reference has been made to the isolat
41、ing function instead of the isolating distance. 3.3 switch-disconnector switch which, in the open position, satisfies the isolating requirements specified for a disconnector SOURCE: IEC 60050-441:1984, 441-14-12 3.4 enclosed switch switch with a dedicated enclosure, providing a specified degree of p
42、rotection against certain external influences 4 Classification Devices according to this standard are classified into two classes, class 0 and class 1. Class 0 is the minimum requirement level, as class 1 is this required by harsh and rough/heavy duty conditions, for example for chemical industries.
