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

Imp: 7kA<\/p>\n

Exibi\u00e7\u00e3o visual.<\/p>\n

Preciso e f\u00e1cil de instalar.<\/p>\n

\u00c9 a combina\u00e7\u00e3o de Classe B (10\/350us) e classe C (8\/20us), utilizada na liga\u00e7\u00e3o equipotencial da zona ZPR 0 e ZPR 2.<\/p>\n

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

Geralmente \u00e9 usado na ind\u00fastria el\u00e9trica.<\/p>\n

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

Fia\u00e7\u00e3o de acordo com a marca do protetor contra surtos de acordo com o esquema el\u00e9trico.<\/p>\n

Quando instalado de acordo com o diagrama de instala\u00e7\u00e3o mostra a conex\u00e3o, onde l (L1, L2, L3) para a linha, n \u00e9 neutro, fio terra PE, n\u00e3o se confunda. Ap\u00f3s a conclus\u00e3o da instala\u00e7\u00e3o, verifique se a unidade de prote\u00e7\u00e3o est\u00e1 conectada, feche a chave do disjuntor autom\u00e1tico (fus\u00edvel) e verifique se o status de funcionamento est\u00e1 normal.<\/p>\n

O protetor em uso durante a janela de exibi\u00e7\u00e3o de falhas deve verificar e visualizar periodicamente o estado quando a janela vermelha de exibi\u00e7\u00e3o de falhas ou o terminal remoto emite sinais de alarme, o protetor falha, deve ser reparado ou substitu\u00eddo em tempo h\u00e1bil.<\/p>\n
