Para a Classe II de equipamentos el\u00e9tricos, de acordo com o m\u00e1ximo permitido da temperatura da superf\u00edcie, ela pode ser dividida em T1 (450\u2103) e T2 (300\u2103).\u2103<\/span>), T3 (200<\/span>\u2103<\/span>), T4 (135<\/span>\u2103<\/span>), T5 (100<\/span>\u2103<\/span>), T6 (85<\/span>\u2103<\/span>) E outros seis de temperatura grupos, e equipamento na temperatura mais alta do grupo pode ser aplicado para as condi\u00e7\u00f5es de uso em temperatura mais baixa do grupo.<\/span><\/p>
