JCM1- Hoʻoheheʻe ʻia ka hihia kaapuni
JCM1 moʻo MoldedʻO Case Circuit Breaker (ma hope aku i kapa ʻia ʻo circuit breaker) he ʻano hou o ka break circuit i hoʻomohala ʻia e kā mākou hui me ka hoʻolālā holomua honua a me ka ʻenehana hana.
Ka pale ʻana i ka ukana, Pale kaapuni pōkole, Ma lalo o ka pale uila
Hoʻohālikelike ʻia ka volta insulation a hiki i 1000V, kūpono no ka hoʻololi pinepine ʻana a me ka hoʻomaka ʻana o ka kaʻa
Hoʻohālikelike ʻia ka volta hana a hiki i 690V,
Loaʻa ma 125A, 160A, 200A, 250A, 300A, 400A, 600A, 800A

Hoʻolauna:
ʻO ka Molded Case Circuit Breakers (MCCB) kahi mea pono o nā ʻōnaehana uila, e hāʻawi ana i ka pale overload a me ka pale pōkole.I ka hapanui o nā hihia, hoʻokomo ʻia nā MCCB i ka papa hāʻawi mana nui o kahi hale, e ʻae i ka ʻōnaehana e pani maʻalahi i ka wā e pono ai.Loaʻa nā MCCB ma nā ʻano nui a me nā helu, ma muli o ka nui o ka ʻōnaehana uila.
Ma kēia alakaʻi, e uhi mākou i nā ʻāpana a me nā hiʻohiʻona o kahi MCCB maʻamau, pehea lākou e hana ai, a me nā ʻano ʻano i loaʻa.E kūkākūkā pū mākou i nā pono o ka hoʻohana ʻana i kēia ʻano haʻihaʻi i kāu ʻōnaehana uila.
ʻO 1000V ka volta insulation i helu ʻia, kūpono ia no ka hoʻololi pinepine ʻana a me ka hoʻomaka ʻana o ka kaʻa i nā kaʻa me AC 50 Hz, helu ʻia ka volta hana a hiki i 690V a helu ʻia i kēia manawa a hiki i 800ACSDM1-800 me ka ʻole o ka pale kaʻa).

He aha ka MCCB?
He ʻano pōkole ʻo MCCB no Molded Case Circuit Breaker.He laʻana maʻamau ia o kahi mea hana palekana uila i hoʻohana pinepine ʻia ma mua o ka hoʻohana ʻole ʻia inā ʻoi aku ka kiʻekiʻe o ke au o ka haʻawe ma mua o ka palena o kahi mea haʻihaʻi kaapuni liʻiliʻi.
Hāʻawi ka MCCB i ka palekana mai nā hewa kaapuni pōkole a hoʻohana ʻia no ka hoʻololi ʻana i nā kaapuni.Hiki ke hoʻohana ʻia no nā helu kiʻekiʻe o kēia manawa a me ka pae hewa, i ka hihia o kekahi mau kumu kūloko.ʻO nā helu ākea o kēia manawa a me ka mana haʻihaʻi kiʻekiʻe i Molded Case Circuit Breaker ʻo ia hoʻi ua kūpono lākou no nā kumu ʻoihana.
Pehea ka hana o ka MCCB?
Hoʻohana ka MCCB i kahi mea ʻike wela (ka mea wela) me kahi mea electromagnetic maʻemaʻe o kēia manawa (ka mea magnetic) e hoʻolako i ka mīkini huakaʻi no ka pale a me ka hoʻokaʻawale ʻana.Hāʻawi kēia i ka MCCB e hāʻawi:
ʻO ka pale ʻana i ka ukana,
Hoʻopaʻa hewa ʻana i ka uila i nā ʻauwai pōkole, a
Hoʻololi uila no ka wehe ʻana.
He aha ka ʻokoʻa ma waena o MCB a me MCCB?
ʻO MCB a me MCCB ka mea maʻamau i hoʻohana ʻia i nā mea pale kaapuni.Hāʻawi kēia mau mea hana i ka pale ʻana ma luna o nā kaapuni o kēia manawa a me ka pōkole.He liʻiliʻi nā ʻokoʻa ma waena o kēia mau mea ʻelua ma waho o ka mana helu o kēia manawa.Loaʻa ka mana o MCB i kēia manawa ma lalo o 125A, a loaʻa ka MCCB a hiki i ka helu o 2500A.
