KDP-20家居安防配电箱是主要针对民用建筑而设计的综合保护配电箱，适用于交流220V单相电源民用配电系统。具有SPD后备保护、过载保护、过 /欠压保护、漏电保护和短路保护的综合功能，既可防止雷电感应和线路浪涌对室内各种用电及通讯设备的冲击和侵扰，又能在电源系统因缺相、相位不平衡、铁磁 谐振、高压断线等故障引起电压突变时，避免造成对家用电器、办公自动化设备、照明设备等电子、电器产品的破坏，还能实现电 源                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                过压、欠压的自动保护和自动复位，同时可防止因电器设备漏电对人身的伤害。
本品具有智能化、功能全、接线方便、结构紧凑、外形美观等特点，是单相电源系统必备的防雷、防漏电、防过压、防欠压、防短路装置，也是办公场所、民用住宅电源设备安全保护的理想选择。
该智能配电单元应安装在电源配电系统的进线端，内部安装了与防雷、防过压、防欠压综合智能化保护模块，还安装了具有过载、短路、漏电保护的开关和保护器，可有效防止接线错误及系统故障而产生的意外事故。
该产品为喷塑铁制箱体，保护等级为IP40。外形采用预埋嵌入式结构，箱内为一路进线、五路出线，并可根据客户需要增加出线。为使防雷、防漏电功能有效，必须将箱内的接地排与箱外就近的大地端子可靠连接。
