Abstract

"APARELHO PARA PROTEGER UM DISPOSITIVO ELéTRICO POLIFáSICO DE SOBRECARGA DE CORRENTE, CONJUNTO CONTATOR E APARELHO DE COMUTAçãO ELéTRICA". Um conjunto contator modular (108) inclui um contator (114A, 114A<39> , 114B, 114C) para cada fase (A, B, C) ou pólo de um dispositivo elétrico. O conjunto contator (108) é aplicável a tanto um dispositivo de comutação quanto um dispositivo de isolação ou proteção de carga. Como tal, cada contator (114A, 114A<39> , 114B, 114C) é construído tal que cada um (114A, 114A<39> , 114B, 114C) inclua múltiplos conjuntos de contatos (118A, 118A<39>, 118B, 118C, 120A, 120A<39>, 120B, 120C) . Além disso, os contatores (118A, 120A) dentro de um único conjunto contator (114A ) ou alojamento pode ser controlado independentemente tal que os contatos (118A, 120A) de um contator (114A) possam ser abertos sem abrir os contatos (118A<39>, 118B, 118C, 120A<39>, 120B, 120C) dos outros contatores (114A<39>, 114B, 114C) do conjunto contator (108).
