Product Detail:

Chigadzirwa chinoenderana neyakajairwa GB14048.2-2008 GB/T22387-2008

Iko kune yemagetsi overcurrent kuburitswa muRCCB yakangwara yasara yazvino yakashanda yedunhu breaker.Ikozvino yakarongerwa yedunhu rinoputika inogadziriswa maererano nemutoro wemutsara.Iyo nhanho-nhatu yekudzivirira curve inochinjika uye iyo RCCB inogona kuwana hierarchical dziviriro neakaderera edunhu mabreak.Iyo yemagetsi overcurrent kuburitswa ine yakakwirira kuchengetedzwa kwechokwadi uye haina kukanganiswa neambient tembiricha uye yekuisa chinzvimbo.Icho chigadzirwa chakasimudzirwa che thermal magnetic overcurrent release.Kune marudzi maviri: ehupfumi RCCB uye yakajairwa RCCB.

Iyo yakangwara moled kesi yasara yazvino yakashanda yedunhu breaker ine RS485 serial interface iyo inogona kuseta yekudzivirira hunhu paramita kuburikidza nemugadziri.Uye iyo RCCB inogona kusangana nezvinodiwa zvekutaurirana network.

Normal Working Conditions:

Ambient tembiricha: -20℃~+60℃
Relative air humidity: Kana avhareji yepamwedzi tembiricha yemwedzi wakanyorova isingapfuure 25 ℃, avhareji yepamwedzi yepamusoro tembiricha yemwedzi haipfuure 90%.Uye iyo condensation pamusoro pechigadzirwa nekuda kwekushanduka kwekushisa kunofanira kuverengwa.
Kuiswa nzvimbo: Iyo yakakwira haipfuure 2000 metres, zvikasadaro inoda kushandiswa nekuderera.
Dhigirii rekusvibisa: Level 3
Kuisa chikamu: III
Simba rekupa sine wave distortion iri pasi pe5%.
Kuisa mamiriro: Iyo yekunze magineti yenzvimbo yekuisa haipfuure 5 nguva geomagnetic munda mune chero nzira.Hapana chinoputika, hapana gasi rinoparadza, hapana mvura nechando kupinda nechisimba, yakaoma, uye inofefetera.
