QCX5-9PM,QCX5-12PM,QCX5-16PM,QCX5-22/20PM 磁力起動(dòng)器
一、 QCX5系列磁力起動(dòng)器適用于交流50Hz或60Hz,額定工作電壓660V及以下,額定工作功率為15kW及以下的電路中,作為控制交流電動(dòng)機(jī)啟動(dòng),停止及過(guò)載保護(hù)之用。QCX5系列磁力起動(dòng)器有交流接觸器、熱過(guò)載繼電器組成,裝于具有一般防塵能力的金屬防護(hù)外殼內(nèi),并有易于操作的按鈕。熱過(guò)載繼電器具有溫度補(bǔ)償及自動(dòng)與手動(dòng)復(fù)位功能,可以板動(dòng)調(diào)節(jié)鈕進(jìn)行電流整定。熱過(guò)載繼電器還帶有斷相保護(hù)機(jī)構(gòu),當(dāng)電動(dòng)機(jī)在斷相運(yùn)轉(zhuǎn)時(shí),能夠切斷電動(dòng)機(jī)電源進(jìn)行斷相保護(hù)。
