For RCBOs other than those operated by means of push-button, the open position shall be indicatedby the symbol “ “ and the closed position b

8、y the symbol “|“ (a short straight line). Additional national symbols are allowed for this indication. Provisionally the use of national indicationsonly is allowed. These indications shall be readily visible when the RCBO is installed. For RCBOs operated by means of two push-buttons, the push-button

9、 designed for the opening operationonly shall be RED and/or be marked with the symbol “O“. RED shall not be used for any other push-button of the RCBO. If a push-button is used for closing the contacts and is evidently identified as such, its depressedposition is sufficient to indicate the closed po

10、sition. If a single push-button is used for closing and opening the contacts and is identified as such, thebutton remaining in its depressed position is sufficient to indicate the closed position. On the otherhand, if the button does not remain depressed, an additional means indicating the position

11、of thecontacts shall be provided. If it is necessary to distinguish between the supply and the load terminals, they shall be clearly marked(e.g. by “line“ and “load“ placed near the corresponding terminals or by arrows indicating the directionof power flow). Terminals exclusively intended for the co

12、nnection of the neutral circuit shall be indicated by the letter N. Terminals intended for the protective conductor, if any, shall be indicated by the symbol (IEC 60417-5019 a). NOTE The symbol (IEC 60417-5017 a), previously recommended, shall be progressively superseded by the preferredsymbol IEC 6

13、0417-5019 a), given above. If a degree of protection higher than IP20 is marked on the device, it shall comply with it, whichever themethod of installation. If the higher degree of protection is obtained only by a specific method ofinstallation and/or with the use of specific accessories (e.g. terminal covers, enclosures, etc.), this shallbe specified in the manufacturers literature&BS EN 61009-1:2004+A14:2012 EN 61009-1:2004+A14:2012 (E)
