EN 50557:2011

Requirements for automatic reclosing devices (ARDs) for circuit breakers-RCBOs-RCCBs for household and similar uses

This European Standard applies to Automatic Reclosing Devices (hereinafter referred to as “ARD”) for household and similar uses, for rated voltage not exceeding 440 V a.c. intended to be used in combination with circuit-breakers and/or RCCBs and/or RCBOs, and designed either for factory assembly or for assembly on site. These devices are intended to reclose main protective devices (hereinafter referred to as “MPD”) such as circuit-breakers complying to EN 60898 1 and/or EN 60898 2, RCCBs complying to EN 61008 1 and RCBOs complying to EN 61009 1 after tripping of those devices in order to re-establish continuity of service. In detail, this European Standard applies to the following types of ARD:  ARD with assessment means, reclosing only if both the prospective line current and the prospective earth-fault current do not exceed given values;  ARD with assessment means, reclosing only if the prospective line current does not exceed a given value;  ARD with assessment means, reclosing only if the prospective earth-fault current does not exceed a given value;  ARD that reclose without any assessment. NOTE 1 The assessment cannot substitute the verifications required by HD 60364 6:2007. NOTE 2 The requirements and tests for the assessment function in IT systems are under consideration. This European Standard does not apply to ARDs with multiple settings adjustable by means accessible to the user in normal service. This European Standard states:  the terms and definitions used for ARD (Clause 3);  the classification of ARD (Clause 4);  the characteristics of ARD (Clause 5);  the preferred values of the operating and influencing quantities (Clause 5);  the marking and information to be provided for ARD (Clause 6);  the standard conditions for installation and operation in service (Clause 7);  the requirements for construction and operation (Clause 8);  the list of minimum requirements to be tested (Clause 9).

Naprave za avtomatski ponovni vklop odklopnikov - Odklopniki na diferenčni tok z nadtokovno zaščito (RCBOs) - Odklopniki na diferenčni tok (RCCBs) za gospodinjsko in podobno uporabo (ARDs)

Ta evropski standard se uporablja za naprave za avtomatski ponovni vklop (ARD)  v gospodinjski in podobni uporabi, kadar naznačena napetost ne presega 440 V izmenične napetosti, pri čemer so te naprave namenjene uporabi v kombinaciji z odklopniki in/ali odklopniki na diferenčni tok (RCCB) in/ali odklopniki na diferenčni tok z nadtokovno zaščito (RCBO) ter zasnovane za sestavo v tovarni ali na kraju samem.
Te naprave so namenjene ponovnemu vklopu glavnih zaščitnih naprav (MPD), kot so odklopniki, skladni s standardom EN 60898-1 in/ali EN 60898-2, odklopniki na diferenčni tok, skladni s standardom EN 61008-1, in odklopniki na diferenčni tok z nadtokovno zaščito, skladni s standardom EN 61009-1, po njihovem izklopu, da se znova vzpostavi neprekinjeno delovanje.
Ta evropski standard se uporablja za naslednje vrste naprav za avtomatski ponovni vklop:
− naprave za avtomatski ponovni vklop z možnostjo ocene, ki napravo znova vklopijo le, če pričakovani linijski tok in pričakovani zemeljskostični tok ne presegata navedenih vrednosti;
– naprave za avtomatski ponovni vklop z možnostjo ocene, ki napravo znova vklopijo le, če pričakovani linijski tok ne presega navedene vrednosti;
– naprave za avtomatski ponovni vklop z možnostjo ocene, ki napravo znova vklopijo le, če pričakovani zemeljskostični tok ne presega določene vrednosti;
– naprave za avtomatski ponovni vklop, ki napravo znova vklopijo brez kakršne koli ocene.
OPOMBA 1: Ocena ne more nadomestiti preverjanj, zahtevanih v standardu HD 60364-6:2007.
OPOMBA 2: Zahteve in preskusi za funkcijo ocenjevanja v sistemih IT se obravnavajo.
Ta evropski standard se ne uporablja za naprave za avtomatski ponovni vklop z več nastavitvami, ki jih lahko uporabnik nastavi med običajnim delovanjem.
Ta evropski standard določa:
− izraze in definicije, ki se uporabljajo za napravo za avtomatski ponovni vklop (točka 3);
− klasifikacijo naprave za avtomatski ponovni vklop (točka 4);
− značilnosti naprave za avtomatski ponovni vklop (točka 5);
− prednostne vrednosti obratovalnih in vplivnih veličin (točka 5);
− označevanje in informacije, ki se predložijo za napravo za avtomatski ponovni vklop (točka 6);
− standardne pogoje za nameščanje in delovanje med obratovanjem (točka 7);
− zahteve za izdelavo in delovanje (točka 8);
− seznam minimalnih zahtev, ki jih je treba preskusiti (točka 9).
