ʻO AC DC Residual Current Circuit Breakers (RCCB) a me Residual Current Circuit Breaker me ka Overload Protection (RCBO) he mau mea koʻikoʻi i loko o nā ʻōnaehana uila no ka hōʻoia ʻana i ka palekana i nā haʻalulu uila a me nā pōʻino ahi. Eia ka hana a kēlā me kēia ʻāpana:

Miniature Circuit Breaker (MCB): ʻO nā MCBs he mau mea electromagnetic i hoʻolālā ʻia e pale i nā kaʻa uila mai ka overcurrents a me ka pōkole pōkole. Loaʻa iā lākou i nā hoʻonohonoho pole like ʻole, me 1P (hoʻokahi pole), 2P (pālua pole), 3P (ʻekolu pole), a me 4P (ʻehā pole), ma muli o ka noi kikoʻī.

Earth Leakage Circuit Breaker (ELCB): Ua hoʻolālā pono ʻia nā ELCB e ʻike i nā au liʻiliʻi liʻiliʻi i hoʻokumu ʻia e nā hewa o nā mea uila a i ʻole nā ​​​​wiea. Hāʻawi lākou i ka palekana mai ka haʻalulu uila ma ka wehe koke ʻana i ke kaapuni ke ʻike ʻia kahi leakage.

ʻO ke koena o kēia manawa (RCCB): Hoʻohana ʻia nā RCCB e pale aku i ka haʻalulu uila ma muli o ka hoʻopili pololei ʻana me nā ʻāpana ola a i ʻole ka hoʻopili pololei ʻana ma o nā mea hana hewa. Ke nānā mau nei lākou i ke koena ma waena o nā au e komo mai ana a me nā au i waho, a laila e ʻike a wehe i ke kaapuni inā loaʻa kahi imbalance o kēia manawa.

RCBO: ʻO ka RCBO kahi hui o kahi MCB a me kahi RCCB a i ʻole kahi ELCB. Hoʻohui ia i ka pale ʻana i nā overcurrents (hana MCB) a me ka pale ʻana i ka leaka honua a i ʻole ke koena o kēia manawa (RCCB a i ʻole ELCB hana) i loko o kahi ʻāpana hoʻokahi.

He mea nui e hoʻomaopopo ʻo AC (alternating current) a me DC (direct current) e pili ana i nā ʻano o ke au uila e hoʻohana ʻia nei. Hoʻolālā ʻia kekahi o kēia mau mea haʻihaʻi kaapuni e hana pono me nā au AC a i ʻole DC, aʻo nā mea ʻē aʻe e hiki ke hana i nā mea ʻelua. I ke koho ʻana i kahi kaapuni, he mea koʻikoʻi ke koho i ke ʻano kūpono no ka ʻōnaehana uila kikoʻī a me ka noi.
