一、用途及適用范圍 INTRODUCTION AND APPLICATIONS T系列熱繼電器適用于交流50HZ或60HZ,電壓至660V,電流至500A的電力線路中。一般用作三相感應(yīng)電動機的過載與斷相保護(hù),常與B系列交流接觸器配合組成電磁起動器。本產(chǎn)品是引進(jìn)德國ABB公司制造技術(shù)的產(chǎn)品。 注:T16為手動復(fù)位,其他為手動和自動復(fù)位。具體見《產(chǎn)品使用說明書》 T series thermal overload relay is mainly suitable for A.C.electric power system with voltage up to 660V,current up to 500A,50-60HZ.It is generally used for the protection of overload and phase-tacking in circuits with three-phasse induce motors and is offen made up electromagnetic starters with B series A.C.contactors. Note:T16 is manually reset aucomatic to the other.AS shown on 《The operating introduction》 二、動作特性:三相負(fù)載平衡時的動作時間 MOTION CHARACTERISTIC:THREE-PHASE BALANCE MOTION TIME |
