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

Os p\u00e1ra-raios BR-25M atendem \u00e0s classes de requisitos Classe I e Classe II conforme IEC 61643-11.<\/p>\n

Conex\u00f5es rotuladas.<\/p>\n

O protetor contra surtos el\u00e9tricos funciona desviando a energia extra do surto el\u00e9trico para longe do circuito principal, geralmente para a \u201cterra\u201d.<\/p>\n

Os dispositivos de prote\u00e7\u00e3o contra surtos (SPD) conectados ao quadro de distribui\u00e7\u00e3o principal monitoram constantemente a tens\u00e3o de alimenta\u00e7\u00e3o.<\/p>\n

\n

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

Esses dispositivos protegem os sistemas consumidores de baixa tens\u00e3o contra sobretens\u00e3o.<\/p>\n

Aplicado em Classe I + Classe II (Classe B + C) para sistema de alimenta\u00e7\u00e3o TT e TN-S.<\/div>\n
