In為斷路器的額定電流,一般指環(huán)境溫度為40攝氏度時的整定值。
10In應(yīng)該是指磁保護(短路保護)的動作值,10In一般用于配電,電動型用12In。
選用時應(yīng)預(yù)算所處線路的額定電流,再乖以安全系數(shù)。對于高溫場所,必須考慮斷路器的降容,具體可參考廠家提供的降容系數(shù)。
淺析低壓斷路器中的微型斷路器
低壓斷路器過去叫自動空氣開關(guān),簡稱空氣開關(guān)或者自動開關(guān),其用途很廣泛,可用于分配電能,不頻繁地啟動異步電動機,對主、支路及電動機等實行保護,在它們發(fā)生嚴重的過載或者短路以及欠電壓等故障時自動切斷電路,它的功能融合了熔斷器式斷流器與過流、欠壓、熱繼電器的功能。并且,斷路器在分斷故障電流后一般不需要更換零部件便可重新恢復(fù)供電,這些優(yōu)點使得它得到越來越廣泛的應(yīng)用。尤其在建筑電氣上,已經(jīng)全部使用斷路器作電路短路、過載保護。

低壓斷路器的主要參數(shù)有:額定電壓、額定電流、極數(shù)、脫扣器類型及其額定電流、整定范圍、電磁脫扣器整定范圍、主觸點分斷能力等。
在選擇低壓斷路器的時候,應(yīng)遵從以下原則:
1,額定電流和額定電壓應(yīng)大于或等于線路、設(shè)備的正常工作電壓和工作電流;
2,極限通斷能力應(yīng)大于或等于電路最大短路電流;
3,欠電壓脫扣器的額定電壓應(yīng)等于線路的額定電壓;Siemens C79298-A3184-B976 C79298A3184B976
