40A 63Amp B Mtundu RCCB 4 Pole 10KA 300mA RCD Mtundu B wa EV Charger Station
Mitundu ya B ndi ma RCCB omwe amakhudzidwa ndi zotsalira zapano zomwe zimapangidwira ntchito zamafakitale pomwe pamakhala kugwiritsa ntchito zida zambiri monga ma frequency converter, zida zamankhwala ndi makina a UPS.Zowonongeka zamtundu wa RCCB Type B zidachitika chifukwa cha mafunde osalala a DC kapena mafunde okhala ndi zotsalira zotsalira zomwe ndizofala pamapulogalamu apamwambawa.
Ma RCCB amtundu wa A/AC sangathe kuzindikira mafunde otsalira osalala a DC.Kuphatikiza apo, mafunde otsala osalala a DC amapangitsa kuti zida za Type A zisamve chidwi ndi mafunde otsalira a AC komanso mafunde otsalira a DC zomwe zimapangitsa kuti pakhale chiwopsezo chachikulu chachitetezo pamayikidwe otere.Pogwiritsa ntchitoType B RCBs mukugwiritsa ntchito kotere titha kutsimikizira chitetezo chokwanira pakuyika konse.Pazifukwa izi, amawonedwa ngati zida zapadziko lonse lapansi popeza amapereka chitetezo kumayendedwe onse oyenda omwe alembedwa mu EN 62423.
