\"Protector<\/p>\n

Protector limitador de corriente trif\u00e1sico de 4 hilos JGFH-125JS<\/a>\u00a0 es un protector integral con una variedad de funciones de protecci\u00f3n tales como sobretensi\u00f3n, subtensi\u00f3n, sobrecorriente, fuga, p\u00e9rdida de fase y falta de cero, y el producto es modular, inteligente, visualizado, etc., y soporta el protocolo de comunicaci\u00f3n est\u00e1ndar Modbus485, y todos los par\u00e1metros de protecci\u00f3n tales como sobretensi\u00f3n<\/a>, La protecci\u00f3n contra sobretensiones, subtensiones y sobrecorrientes puede ajustarse en funci\u00f3n de la demanda de potencia, para garantizar que no se produzcan sobretensiones, subtensiones, sobrecorrientes, corrientes de fuga, cortocircuitos, p\u00e9rdidas de fase, etc. en la l\u00ednea. En caso de fallo, como la falta de cero, el protector puede cortar instant\u00e1neamente el suministro el\u00e9ctrico para proteger los equipos el\u00e9ctricos de posibles da\u00f1os.<\/p>\n

Condiciones de trabajo<\/h2>\n
\n

1. El primer retardo de encendido normal es de 20 segundos y se cierra autom\u00e1ticamente; En caso de sobretensi\u00f3n, subtensi\u00f3n, sobrecorriente y fuga cuando se enciende por primera vez, el producto se desconectar\u00e1 autom\u00e1ticamente en 3 segundos;<\/p>\n

2. La temperatura ambiente no supera los +40 \u00b0C, no es inferior a -5 \u00b0C, y la temperatura media de 24 horas no supera los +35 \u00b0C; A +40 \u00b0C, la humedad del aire ambiente no supera los 50%.<\/p>\n

3. La altura del dial marino en el lugar de instalaci\u00f3n no superar\u00e1 los 2000 metros.<\/p>\n

4. Nivel de contaminaci\u00f3n III.<\/p>\n

5. En el entorno de instalaci\u00f3n, no hay ning\u00fan medio con riesgo de explosi\u00f3n, ning\u00fan gas corrosivo y aislante y polvo conductor, y ninguna invasi\u00f3n de lluvia y nieve.<\/p>\n
