series Intelligent type universal circuit breaker Appliance RDW2-1600 Intelligent type Air circuit breaker, is mainly applied to power distribution network of rated operational voltage up to 690V, rated current from 200A to 1600A. It used to distribute power and protect circui and power-supply equipment against damages of overload, under-voltage, short-circuit, single-phase grounding(leakage) this kind fault. And circuit breaker has Intelligent protection functions, accurated selective protection function, and it can rise power-supply reliability to aviod unneccessary power interruption. And it also has common communication port to connect with fieldbus conveniently and realizes the remote function to meet the requirements of control center and automatic system. The corresponding leakage transformer and intelligent controller can realize leakage protection. This protection has isolation functions, the sign is . This productio which rated operational current below 630A, is also can be used to power-distribution network of AC50(60)Hz, 400V for protecting Motor against overload, short-circuit, phase-loss, under-voltage and grounding fault this kinds fault. Under normal condition, it also can be used to transfer circuit unfrequently and start motor unfrequently. This production conforms to standard of GB14048.1-2012, GB14048.2-2008, GB14048.4-2010.

Action feature is delay type, conforms to Tabel 7.(Not including controller inherent action time 20ms.) Rated residual action current :3A,10A,20A,30A Rated residual no-action current Minimum :

series Intelligent type universal circuit breaker Table 7 Ultimate no drive time residual current 4.5.8 Grounding or residual current protection type Grounding or residual current protection is a protection for equipment because the equipment has leakage current to earth. According to leakage current, it is divied into Grounding protection and residual current protection. Grounding protection is protected by controller according to 3-phases and neutral current vector sum. According to poles, it has 3PT, 4PT,(3P+N)T, three type protection mode.(see Fig 3.) Residual current protection is...
