el\u00e9ctricas. Los gabinetes el\u00e9ctricos suelen incluir componentes electr\u00f3nicos que, en algunos casos, podr\u00edan generar chispas. Las chispas pueden causar riesgos de explosi\u00f3n al entrar en contacto con materiales inflamables. Por lo tanto, es fundamental utilizar gabinetes que ofrezcan la protecci\u00f3n necesaria contra explosiones.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Se utilizan envolventes NEMA 7 en \u00e1reas donde pueden producirse vapores inflamables. Por ejemplo, este tipo de envolvente es adecuado para plantas qu\u00edmicas y refiner\u00edas de petr\u00f3leo. Las envolventes NEMA 7 garantizan la seguridad al evitar explosiones.

Debido a su prop\u00f3sito, la norma NEMA 7 se compone de materiales de alta resistencia como el aluminio o el hierro fundido. Estos materiales pueden resistir explosiones internas. Adem\u00e1s, estos gabinetes cuentan con rutas de escape de llamas para liberarlas de forma segura.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Los gabinetes NEMA 4X est\u00e1n fabricados con diferentes materiales, como aluminio, acero inoxidable e incluso pl\u00e1stico.

Estos sellos impiden que las llamas sean dispersadas por el viento. NEMA 7 puede prevenir la propagaci\u00f3n del fuego y garantizar la integridad del gabinete gracias a sus sellos.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Aunque los gabinetes NEMA 4X tambi\u00e9n cuentan con sellos, estos son resistentes a la intemperie.

Los gabinetes NEMA 7 son m\u00e1s costosos que los NEMA 4X debido a sus procedimientos de prueba, construcci\u00f3n robusta y los materiales utilizados en su dise\u00f1o. Estos gabinetes deben someterse a pruebas para garantizar que cumplan con los requisitos de protecci\u00f3n contra explosiones.
