ABB REA 101 loka aizsardzības relejs

 Apraksts

The ABB REA101 ir ātrs loka kļūdu aizsardzības relejs vidēja un zema sprieguma sadalnes iekārtām.
Tas nosaka loka kļūdas ar optisko šķiedru sensoriem un izsūta izslēgšanas signālus 2,5 ms laikā.
Šī ātrā reakcija palīdz samazināt iekārtu bojājumus un uzlabo personāla drošību.
Relejs viegli integrējas esošajās sistēmās ar elastīgām montāžas un komunikācijas iespējām.
