EN 61643-21:2001

Low voltage surge protective devices - Part 21: Surge protective devices connected to telecommunications and signalling networks - Performance requirements and testing methods

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 voltags up to 1 000 V (r.m.s.) a.c. and 1 500 V d.c.

Parafoudres basse-tension - Partie 21: Parafoudres connectés aux réseaux de signaux et de télécommunications - Prescriptions de fonctionnement et méthodes d'essais

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 fontionnement jusqu'à 1 000 V (efficace) en courant alternatif et 1 500 V en courant continu.
