從1P到4P(1P的厚度是18MM,2P是36MM......),1P就是1根線進(jìn)出,2P就是2根線進(jìn)出,以此類推。家里一般就用到1P或者2P,1P和2P的區(qū)別就是1P只能斷開1根火線,2P是能同時(shí)斷開火線和零線也就是1P+N,所以相對(duì)來說2P的更好點(diǎn)。如果你負(fù)載的設(shè)備額定電壓是220V時(shí),就可以用1P或2P的空氣開關(guān),如果是380V,就需要3P或4P了,對(duì)負(fù)載設(shè)備不需要零的就只選3P就可以了,如電動(dòng)機(jī)、風(fēng)機(jī)、水泵等只用3P空氣開關(guān);如是380V的開水器、熱水器之類的設(shè)備,就需要4P了,而且還要帶漏電保護(hù)功能的空氣開關(guān),這是為防止漏電事故,保障人身安全是必須的要用的。
空氣開關(guān)型號(hào)有哪些?

轉(zhuǎn)子流量計(jì)在工業(yè)生產(chǎn)過程中應(yīng)用較廣,可以測(cè)量多種介質(zhì)的流量,特別適用于中小管徑和低雷諾數(shù)的中小流量測(cè)量。轉(zhuǎn)子流量計(jì)結(jié)構(gòu)簡(jiǎn)單,靈敏度高,量程比寬(10:1),壓力損失小且恒定,對(duì)直管段的要求不高,刻度近似線性,價(jià)格便宜,使用維護(hù)簡(jiǎn)便。但儀表受被測(cè)介質(zhì)密度、粘度、溫度、壓力等因素的影響,其精度一般在1.5級(jí)左右。
目前家庭使用DZ系列的空氣開關(guān)(帶漏電保護(hù)的小型斷路器),常見的有以下型號(hào)/規(guī)格:C16、 C25、C32、C40、C60、C80、C100、C120等規(guī)格,其中C表示脫扣電流,即起跳電流,例如C32表示起跳電流為32安,一般安裝6500W熱水器要用C32,安裝7500W、8500W熱水器要用C40的空開。
