Kei te pirangi koe ki nga Kaiwhati Porowhita Leakage o te Ao teitei me te roa?CDADAe whakarato ana i nga otinga whakaritenga OEM matawhānui. Hei kaihanga pono me o maatau wheketere, ka tukuna e matou he raihana 3-tau mo o maatau hua.

He aha te mea he Wehenga Whakawhiti Haowhiti Leakage (CBR)?

HeKaiwhati iahiko Leakage o te whenua (CBR), e mohiotia ana anoKaiwhati iahiko turuturu o te whenua me te parenga o te ia (CBR) mo ia IEC 60947-2 Annex B, he taputapu whakamarumaru ngaohiko iti e whakakotahi ana.te toenga o naianei (te turuturu whenua) whakamarumaru mete taumaha me te tiaki iahiko poto i roto i te waeine take whakarewa kotahi. E mahi ana i nga ngaohiko reiti ki te415V AC (50/60Hz) me nga whakatauranga o naianei mai i16A ki te 800A, Ka noho nga CBR hei taputapu whakamarumaru matawhānui mo nga tono hangahanga ahumahi, arumoni, me te tino nui.

Kaore i rite ki te takitahiWehenga Waahi Iahiko Naianei (RCCBs)e whakarato ana i te whakamarumaru riipapa whenua anake, ka whakauru nga CBR:

Te whakamarumaru ngaa-aukume, hiko hiko ranei (Nga pihi L-S-I)

Te kitenga o naianei toenga (10mA ki te 1000mA tairongo)

Te kaha pakaru iahiko-poto tae atu ki te 85kA

Ko tenei whakaurunga ka whakakore i te hiahia mo nga huinga MCB/RCCB motuhake, te whakaiti i te waahi whakaurunga me te whakapai ake i te pono o te ruruku.
