從外形結構區分，電(dian)控柜、配(pei)電(dian)柜（配(pei)電(dian)盤）是一類的，電(dian)控箱和配(pei)電(dian)箱是一類的。

電控箱(xiang)和(he)配電箱(xiang)是六(liu)面(mian)密封，一般都是掛墻安裝，箱(xiang)的頂部和(he)下部有敲落孔，便于電線、電纜的出入電控、配電箱(xiang)。

電控(kong)柜(ju)、配電柜(ju)為五面密封，沒有底部，一般都是落地靠墻(qiang)安裝。

配(pei)電(dian)盤一般(ban)為(wei)兩面密(mi)封，也有三(san)面、四(si)面、五(wu)面密(mi)封的，配(pei)電(dian)盤都是(shi)落地安裝，但(dan)后(hou)面不能靠墻，配(pei)電(dian)盤的后(hou)面必須留有操作和維護空間。

配電盤(pan)具體幾面密封，訂貨時(shi)需(xu)要(yao)(yao)提出要(yao)(yao)求。比如五個(ge)配電盤(pan)并排連續安裝，只(zhi)有(you)第(di)一(yi)個(ge)左側(ce)需(xu)要(yao)(yao)擋板，第(di)五個(ge)右側(ce)需(xu)要(yao)(yao)擋板，第(di)二、三、四個(ge)左右兩(liang)側(ce)均敞(chang)開。如果一(yi)個(ge)配電盤(pan)獨立安裝使用，左右兩(liang)側(ce)需(xu)要(yao)(yao)都有(you)擋板。

大部分情況(kuang)下配電盤后(hou)面都(dou)是敞開的(de)，根(gen)據用戶(hu)需要后(hou)面也可以有門，既(ji)能防(fang)塵(chen)，又方便操(cao)作和維護(hu)。

從功(gong)能角度區分，配電(dian)盤、配電(dian)柜和配電(dian)箱是(shi)屬于一類的，電(dian)控箱和電(dian)控柜是(shi)屬于一類的。

一般來(lai)說配(pei)(pei)(pei)(pei)電(dian)(dian)盤是(shi)將電(dian)(dian)能(neng)(neng)分配(pei)(pei)(pei)(pei)給(gei)下級配(pei)(pei)(pei)(pei)電(dian)(dian)柜(ju)、配(pei)(pei)(pei)(pei)電(dian)(dian)箱(xiang)，或者直接將電(dian)(dian)能(neng)(neng)分配(pei)(pei)(pei)(pei)給(gei)用(yong)電(dian)(dian)設備， 配(pei)(pei)(pei)(pei)電(dian)(dian)柜(ju)、配(pei)(pei)(pei)(pei)電(dian)(dian)箱(xiang)直接將電(dian)(dian)能(neng)(neng)分配(pei)(pei)(pei)(pei)給(gei)用(yong)電(dian)(dian)設備，有(you)時也用(yong)配(pei)(pei)(pei)(pei)電(dian)(dian)柜(ju)是(shi)將電(dian)(dian)能(neng)(neng)分配(pei)(pei)(pei)(pei)給(gei)下級配(pei)(pei)(pei)(pei)電(dian)(dian)箱(xiang)。

 電控箱、電控柜是主要用于(yu)控制用電設備(bei)，同時也(ye)兼有將電能分配(pei)給用電設備(bei)的功能。

配(pei)(pei)電(dian)(dian)(dian)(dian)柜(ju)(ju)、配(pei)(pei)電(dian)(dian)(dian)(dian)箱(xiang)及配(pei)(pei)電(dian)(dian)(dian)(dian)盤(pan)內(nei)主要安(an)(an)裝(zhuang)刀開(kai)(kai)關(guan)(guan)、刀熔開(kai)(kai)關(guan)(guan)、空氣開(kai)(kai)關(guan)(guan)、熔斷器(qi)(qi)(qi)、磁(ci)力起動器(qi)(qi)(qi)（接觸器(qi)(qi)(qi)）、熱繼電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，有時也會安(an)(an)裝(zhuang)電(dian)(dian)(dian)(dian)流(liu)互感(gan)器(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)壓(ya)互感(gan)器(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)流(liu)表(biao)(biao)、電(dian)(dian)(dian)(dian)壓(ya)表(biao)(biao)、電(dian)(dian)(dian)(dian)度表(biao)(biao)等(deng)，電(dian)(dian)(dian)(dian)控(kong)(kong)箱(xiang)、電(dian)(dian)(dian)(dian)控(kong)(kong)柜(ju)(ju)內(nei)除(chu)了(le)安(an)(an)裝(zhuang)上述電(dian)(dian)(dian)(dian)氣元器(qi)(qi)(qi)件之外，還(huan)會安(an)(an)裝(zhuang)中間繼電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)、時間繼電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)、控(kong)(kong)制按鈕、指示燈、轉換開(kai)(kai)關(guan)(guan)及其他功能的(de)開(kai)(kai)關(guan)(guan)和控(kong)(kong)制設備，有的(de)甚至將(jiang)變(bian)頻器(qi)(qi)(qi)、PLC、單片機、I/O轉換器(qi)(qi)(qi)件、交直流(liu)變(bian)壓(ya)穩壓(ya)器(qi)(qi)(qi)等(deng)安(an)(an)裝(zhuang)在電(dian)(dian)(dian)(dian)控(kong)(kong)箱(xiang)、電(dian)(dian)(dian)(dian)控(kong)(kong)柜(ju)(ju)里面(mian)(mian)，個別還(huan)會將(jiang)溫(wen)度、壓(ya)力、流(liu)量(liang)的(de)顯示儀表(biao)(biao)安(an)(an)裝(zhuang)在電(dian)(dian)(dian)(dian)控(kong)(kong)箱(xiang)、電(dian)(dian)(dian)(dian)控(kong)(kong)柜(ju)(ju)上面(mian)(mian)。
