无论插头是否插入,插座和连接器在正确安装后都应保证其所定义的防护等级。插头和装置插头的防护等级仅适用于插入相应的连接器且防护盖(如有)盖上时。插头插座必须对应IP 44 或IP 67。额定电流为 100/125A 的插头插座防护等级必须达到 IP 67,额定电流为100/125 A 插座安装在箱体上构成成套设备时的防护等级可以为IP44。对于防护等级为IP67 的插座,卡口旋式装置的使用已成为标准,目的是为了简化使用,尤其是在恶劣环境下。防护等级IP44 或IP67 已在产品上标示出。
使用SCHUKO®插座时,请注意,由于结构的原因,只有在盖子关闭时才能达到防护等级。否则,可能无法防止地面接触区域的水渗入(参见DIN VDE 0620-1和DIN 49440及以下)
