Low-voltage switchgear and controlgear - Part 3: Switches, disconnectors, switch-disconnectors and fuse-combination units (IEC 60947-3:2008/A1:2012)

This International Standard is applicable to replaceable lamps (filament lamps and discharge lamps) to be used in headlamps, fog-lamps and signalling lamps for road vehicles. It is especially applicable to those lamps which are the subject of legislation. In particular, it includes the lamps contained in Regulations1) No.37 and No.99 of the Geneva Agreement of 20 March 1958 of the United Nations Economic Commission for Europe (ECE). However, the standard may be used for other lamps falling under the scope of this standard. The standard specifies the technical requirements with methods.

Le contenu du corrigendum de novembre 2013 a été pris en considération dans cet exemplaire.

Nizkonapetostne stikalne in krmilne naprave - 3. del: Stikala, ločilniki, ločilna stikala in stikalni aparati z varovalkami (IEC 60947-3:2008/A1:2012)

Ta del standarda IEC 60947 se uporablja za stikala, ločilnike, ločilna stikala in stikalne aparate z varovalkami, ki so namenjeni uporabi v razdelilnih tokokrogih in motorskih tokokrogih, pri čemer nazivna napetost ne presega 1000 V izmenične napetosti ali 1500 V enosmerne napetosti. Proizvajalec mora določiti vrsto, mejne vrednosti in značilnosti vseh vključenih varovalk v skladu z ustreznim standardom. Ta del se ne uporablja za opremo, ki spada v področje uporabe standardov IEC 60947-2, IEC 60947-4-1 in IEC 60947-5-1; vendar morajo biti stikala in stikalni aparati z varovalkami, ki bodo spadali v področje uporabe tega dela in se običajno uporabljajo za zagon, pospeševanje in/ali ustavljanje posameznega motorja, prav tako skladni z dodatnimi zahtevami iz dodatka A. Zahteve za tripolna stikala z enim samim priključnim polom so zajete v dodatku C. Pomožna stikala, pritrjena na opremo, ki spada v področje uporabe tega dela, morajo biti skladna z zahtevami standarda IEC 60947-5-1. Ta del ne zajema dodatnih zahtev, potrebnih za električne naprave za eksplozivne plinske atmosfere.

disconnector

mechanical switching device which, in the open position, complies with the requirements

specified for the isolating function

NOTE 1 This definition differs from IEC 60050-441:1984, 441-14-05 by referring to isolating function instead of

isolating distance.

NOTE 2 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 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.

switch in which a fuse-link or fuse-carrier with fuse-link forms the moving contact
