功能性
緊湊型 SIRIUS 3RW40 軟起動(dòng)器所需的空間僅為用于比較額定值 wye-delta 起動(dòng)的接觸器所需空間的三分之一。這不僅節(jié)約了控制柜和標(biāo)準(zhǔn)安裝導(dǎo)軌的空間，還*省去了 wye-delta 起動(dòng)器所需的布線工作。這對(duì)于高電機(jī)額定值尤為明顯，這些高額定值極少用作高技術(shù)解決方案。

 同時(shí)，連接起動(dòng)器和電機(jī)所需的電纜從六根減少到三根。緊湊的外形尺寸、短起動(dòng)時(shí)間、簡(jiǎn)單布線和快速調(diào)試使得軟起動(dòng)器具有明顯的成本優(yōu)勢(shì)。

 這些軟起動(dòng)器的旁通觸點(diǎn)在工作時(shí)由一個(gè)集成固態(tài)滅弧系統(tǒng)保護(hù)。從而在故障時(shí)可防止對(duì)旁通觸點(diǎn)的破壞，如線圈操作機(jī)構(gòu)或主操作彈簧的短暫的控制電壓故障、機(jī)械震動(dòng)或與壽命相關(guān)的部件缺陷。

 特別強(qiáng)大的操作機(jī)構(gòu)的起動(dòng)電流會(huì)在本地供電系統(tǒng)上施加一個(gè)不可控制的負(fù)荷。軟起動(dòng)器通過其電壓軟起動(dòng)降低了該起動(dòng)電流。 通過可調(diào)電流限值功能，SIRIUS 3RW40 軟起動(dòng)器為供電系統(tǒng)緩解了不少壓力。一達(dá)到選擇的電流限值，剩下的只需設(shè)置軟起動(dòng)期間的起動(dòng)起點(diǎn)（軟起動(dòng)升降率由起動(dòng)電壓和軟起動(dòng)時(shí)間決定）。從此刻開始，可通過控制軟起動(dòng)器電壓以使電機(jī)電流保持為常數(shù)?？赏ㄟ^電機(jī)軟起動(dòng)完成、本征設(shè)備保護(hù)脫扣或電機(jī)過載保護(hù)脫扣來結(jié)束該過程。該功能的結(jié)果就是電機(jī)的實(shí)際軟起動(dòng)時(shí)間要比軟起動(dòng)器上選擇的軟起動(dòng)時(shí)間長。
