    CSA Preface


    This is the first edition of CSA C22.2 No. 61643-21, Low voltage surge protective devices — Part 21: Surge protective devices connected to telecommunications and signaling networks — Performance requirements and testing methods, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61643-21 (edition 1:2000 consolidated with Amendment 1:2008 and Amendment 2:2012). It replaces CSA C22.2 No. 226-92, Protectors in telecommunication networks. It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code.


    For brevity, this Standard will be referred to as CSA C22.2 No. 61643-21 throughout.


    This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.


    This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.


    Scope


    This International Standard is applicable to devices for surge protection of telecommunications and signalling networks against indirect and direct effects of lightning or other transient overvoltages.


    The purpose of these SPDs is to protect modern electronic equipment connected to telecommunications and signalling networks with nominal system voltages up to 1 000 V (r.m.s.) a.c. and 1 500 V d.c.

    Préface CSA


    Ce document constitue la première édition de CSA C22.2 nº 61643-21, Parafoudres basse tension — Partie 21 : Parafoudres connectés aux réseaux de signaux et de télécommunications — Prescriptions de fonctionnement et méthodes d’essais. Il s’agit de l’adoption, avec exigences propres au Canada, de la norme IEC (Commission Électrotechnique Internationale) 61643-21 (édition 1:2000 consolidée par l’amendement 1:2008 et l’amendement 2: 2012), qui porte le même titre. Il remplace CSA C22.2 nº 226-92, Protecteurs de réseaux de télécommunications. Il fait partie d’une série de normes publiées par Groupe CSA qui constituent le Code canadien de l’électricité, Deuxième partie.


    Par souci de brièveté, tout au long de ce document, il sera appelé « CSA C22.2 nº 61643-21 ».


    Cette norme est jugée convenable à l’évaluation de la conformité selon le domaine d’application établi dans la norme.


    Cette norme a été élaborée conformément aux exigences du Conseil canadien des normes relatives aux Normes nationales du Canada. Cette norme a été publiée en tant que Norme nationale du Canada par Groupe CSA.


    Domaine d’application


    La présente Norme internationale est applicable aux dispositifs de protection (parafoudres) contre les effets directs et indirects de la foudre ou des autres surtensions transitoires, pour les réseaux de télécommunications et de transmission de signaux.


    Ces parafoudres sont destinés à protéger les équipements électroniques modernes, connectés aux réseaux de télécommunications et de transmission de signaux, ayant une tension nominale de fonctionnement jusqu’à 1 000 V (efficace) en courant alternatif et 1 500 V en courant continu.
