Caracter\u00edsticas:<\/strong><\/p>\n

\u2022 Este \u00e9 um tipo de dispositivo de prote\u00e7\u00e3o contra surtos de alta qualidade, \u00e0 prova de fogo e resistente \u00e0 corros\u00e3o. Reaja rapidamente com velocidade com forte capacidade de carga.<\/p>\n

\u2022 Simples e f\u00e1cil de usar. Mais confi\u00e1vel e mais seguran\u00e7a.<\/p>\n

\u2022 Janela indicadora de status de trabalho, vermelho significa falha, o que pode efetivamente reagir ao status de trabalho a tempo.<\/p>\n

\u2022 Prote\u00e7\u00e3o contra surtos, evita que a rede el\u00e9trica dom\u00e9stica receba impacto excessivo durante raios.<\/p>\n

\u2022 Projeto de instala\u00e7\u00e3o em trilho Din remov\u00edvel de 35 mm.<\/p>\n

\n

Aplicativo:<\/strong><\/p>\n

\u2022 Protege as instala\u00e7\u00f5es el\u00e9ctricas contra descargas atmosf\u00e9ricas directas e descarrega a contracorrente dos raios que se espalham do condutor de terra para os condutores da rede.<\/p>\n

\u2022 Usado para sistema de energia CA, sistema de distribui\u00e7\u00e3o de energia, dispositivos terminais, equipamentos eletr\u00f4nicos, edif\u00edcios, empresas industriais e institutos m\u00e9dicos, etc.<\/p>\n

Instala\u00e7\u00e3o:<\/strong><\/p>\n

DPS Tipo 1 ou Tipo 1+2 (Iimp \u2265 12,5 kA) obrigat\u00f3rio na fonte de instala\u00e7\u00e3o (quadro de distribui\u00e7\u00e3o principal em edif\u00edcios secund\u00e1rios).<\/p>\n

Instala\u00e7\u00f5es com mais de 10 m de altura (edif\u00edcios de apartamentos, edif\u00edcios de escrit\u00f3rios, hot\u00e9is, etc.): DPS tipo 2 recomendado para prote\u00e7\u00e3o de \u00e1reas privadas e distribuidores de piso (\u00e1reas comuns) al\u00e9m de DPS tipo 1 ou tipo 1+2.<\/p>\n
