Mea Wehe Kaapuni liʻiliʻi (MCB) CJM2-63-2
Kūkulu a me nā hiʻohiʻona
- Kiʻekiʻe pōkole-pōkole kaha 10KA
- Hoʻolālā ʻia e pale i ke kaapuni e lawe ana i kēia manawa nui a hiki i 63A
- Hōʻike kūlana hoʻopili
- Hoʻohana ʻia e like me ke kī nui i ka hale a me ka hoʻonohonoho like

ʻO nā hiʻohiʻona pale o kēia manawa
| Hoao | ʻAno kaʻahele | Hoao i keia manawa | Mokuaina mua | ʻO ka manawa hele a i ʻole ka mea hoʻolako manawa ʻole | |

He aha ka MCB?
ʻO ka mea haʻihaʻi kaapuni liʻiliʻi (MCB) kahi ʻano o ka mea haʻihaʻi kaapuni liʻiliʻi ka nui.ʻOki koke ia i ke kaapuni uila i ka wā o ke ʻano maikaʻi ʻole o nā ʻōnaehana lako uila, e like me ka overcharge a i ʻole ke ʻano pōkole.ʻOiai hiki i ka mea hoʻohana ke hoʻonohonoho hou i ka MCB, hiki i ka fuse ke ʻike i kēia mau kūlana, a pono ka mea hoʻohana e hoʻololi iā ia.
ʻO ka MCB kahi mea electromagnetic e pale ana i nā uwea uila a me nā ukana mai ka ʻāʻī ʻana, pale i ke ahi a me nā pilikia uila ʻē aʻe.ʻOi aku ka palekana o ka MCB, a hoʻihoʻi koke i ka mana.No ka hoʻouka ʻana a me ka pale kaapuni transient i nā noi noho, ʻo ka MCB ka koho kaulana loa.He wikiwiki loa ka MCB a ʻaʻole pono e mālama.Hoʻohana ʻia ka manaʻo hoʻohui bi-metal i nā MCB no ka pale ʻana i ke au kahe a me ke au kaapuni pōkole.
