Introdu\u00e7\u00e3o geral<\/strong><\/h3>\n

O contator a v\u00e1cuo CKG3 \u00e9 usado principalmente no sistema de energia com CA de 50 Hz e tens\u00e3o nominal de 7,2 kV, para fazer ou interromper o circuito e dar partida eletromagn\u00e9tica com o dispositivo de prote\u00e7\u00e3o adequado e o painel de distribui\u00e7\u00e3o F-C.<\/p>\n

Condi\u00e7\u00f5es de trabalho<\/strong><\/h3>\n

A altitude acima do mar n\u00e3o deve ser superior a 1.000 m;<\/p>\n

A temperatura ambiente \u00e9 de -5 a 40\u00b0C;<\/p>\n

Temperatura m\u00e9dia em 24 horas limitada abaixo de 35\u00b0C;<\/p>\n

Quando a temperatura mais alta for 40\u00b0C, a umidade relativa n\u00e3o deve ser superior a 50%;<\/p>\n
