描述

許多時候，引起斷路器跳閘的原因就是斷路器的選型錯誤。尤其是在進(jìn)行電路改造時，一定要注意觀察斷路器的型號，必要時，應(yīng)及時更換。

斷路器在進(jìn)行選型時應(yīng)做如下考慮：

電線線方：斷路器的電流，應(yīng)小于電線的載流量。否則，很可能發(fā)生過載不跳閘的情況，起不到保護(hù)作用。

總開關(guān)電流：支路開關(guān)的電流，應(yīng)小于總開關(guān)電流，以免發(fā)生越級跳閘的現(xiàn)象。

插座數(shù)量：如果該回路插座數(shù)量過多，應(yīng)考慮增加斷路器電流和干路電線的線方，以免造成過載。

斷路器級數(shù)：一般情況下，從經(jīng)濟(jì)角度和安全角度考慮，普通五孔插座回路的斷路器可以使用單極斷路器，而大功率電器所用的三孔插座回路，需要使用二極斷路器。

斷路器的保護(hù)功能：所有插座回路，必須使用帶漏電的斷路器，電燈回路和主開關(guān)不建議使用漏電斷路器，以免發(fā)生誤動作。

常見的漏電斷路器選型為1PC16漏電斷路器、1PC20漏電斷路器和2PC32漏電斷路器。Cxx即斷路器的額定電流為xx安。

一般來說，家用配電箱支路開關(guān)的斷路器電流不得大于32A，因為樓道內(nèi)的電線為6平方，單用戶電流過大，容易造成樓道失火。
