ʻO ka JCRB2-100 Type B RCDs nā mea hana palekana uila i hoʻolālā ʻia e hāʻawi i ka pale piha i nā ʻano hewa like ʻole i nā ʻōnaehana uila hou. ʻO kā lākou mau hiʻohiʻona nui:

ʻO ke ʻano o ka hele ʻana: 30mA

ʻO ka ʻike ʻana o ka 30mA ma ka JCRB2-100 Type B RCDs, ʻo ia ka mea e pani koke ka hāmeʻa i ka lako mana inā ʻike ia i kahi leaka uila o 30 milliamps (mA) a i ʻole. He mea koʻikoʻi kēia kiʻekiʻe o ka naʻau no ka hōʻoia ʻana i kahi kiʻekiʻe o ka pale ʻana i nā haʻalulu uila a i ʻole nā ​​​​ahi ahi i hoʻokumu ʻia e nā hewa o ka honua a i ʻole nā ​​au leakage. Hiki ke pilikia loa ka leakage o 30mA a i ʻole, hiki ke hōʻeha nui a make paha ke waiho ʻole ʻia. Ma ka hele ʻana i kēia pae haʻahaʻa o ka leakage, kōkua ka JCRB2-100 i ka pale ʻana i kēlā ʻano pōʻino mai ka hiki ʻana mai, e ʻoki koke i ka mana ma mua o ka hiki ʻana o ka hewa ke hōʻeha.

2-Pole / Māhele Hoʻokahi

Hoʻolālā ʻia nā JCRB2-100 Type B RCD ma ke ʻano he 2-pole, ʻo ia ka mea i manaʻo ʻia no ka hoʻohana ʻana i nā ʻōnaehana uila hoʻokahi. Loaʻa nā ʻōnaehana hoʻokahi i nā hale noho, nā keʻena liʻiliʻi, a me nā hale kūʻai māmā. Ma kēia mau hoʻonohonoho, hoʻohana mau ʻia ka mana hoʻokahi no ka hoʻoulu ʻana i nā kukui, nā mea hana, a me nā ukana uila liʻiliʻi ʻē aʻe. ʻO ka hoʻonohonoho 2-pole o ka JCRB2-100 hiki iā ia ke nānā a pale i nā mea hoʻokele ola a me ke kūʻokoʻa i kahi kaapuni hoʻokahi, e hōʻoiaʻiʻo ana i ka pale piha ʻana i nā hewa e hiki mai ana ma kēlā me kēia laina. ʻO kēia ka mea i kūpono i ka hāmeʻa no ka mālama ʻana i nā mea hoʻonohonoho hoʻokahi-phase, i laha ʻia i nā kaiapuni o kēlā me kēia lā.

Ka helu o kēia manawa: 63A

ʻO ka JCRB2-100 Type B RCDs i kēia manawa he 63 amps (A). Hōʻike kēia helu i ka nui loa o ke au uila hiki ke mālama pono ʻia ma lalo o nā kūlana hana maʻamau me ka ʻole o ka hele ʻana a i ʻole ke kaumaha. I nā huaʻōlelo ʻē aʻe, hiki ke hoʻohana ʻia ka JCRB2-100 e pale i nā kaʻa uila me nā ukana a hiki i 63 amps. ʻO kēia helu helu o kēia manawa e kūpono i ka hāmeʻa no kahi ākea o nā hale noho a me nā noi kalepa māmā, kahi e hāʻule pinepine ai nā ukana uila i loko o kēia pae. Eia nō naʻe, he mea nui e hoʻomaopopo ʻoiai inā aia ka manawa i loko o ka helu 63A, e holo mau ana ka JCRB2-100 inā ʻike ʻo ia i kahi leakage o 30mA a ʻoi aku paha, no ka mea, ʻo ia kona pae naʻau tripping no ka pale hewa.

Ka helu Voltage: 230V AC

Loaʻa i ka JCRB2-100 Type B RCDs ka helu voltage o 230V AC. ʻO ia ke ʻano ua hoʻolālā ʻia lākou e hoʻohana ʻia i nā ʻōnaehana uila e hana ana ma kahi volta nominal o 230 volts alternating current (AC). He mea maʻamau kēia helu volta i ka nui o nā hale noho a me nā noi pāʻoihana māmā, e kūpono ana ka JCRB2-100 no ka hoʻohana ʻana i kēia mau kaiapuni. He mea nui e hoʻomaopopo ʻaʻole pono e hoʻohana ʻia ka hāmeʻa i nā ʻōnaehana uila me nā volt i ʻoi aku ka kiʻekiʻe ma mua o kāna volta helu helu, no ka mea hiki ke hōʻino i ka hāmeʻa a i ʻole e hoʻololi i kona hiki ke hana pono. Ma ka hoʻopili ʻana i ka helu 230V AC voltage, hiki i nā mea hoʻohana ke hōʻoia i ka JCRB2-100 e hana palekana a maikaʻi hoʻi i loko o kāna pae uila i manaʻo ʻia.

Kaha Kaapuni Pokole i kēia manawa: 10kA

ʻO ka mana o ka JCRB2-100 Type B RCD i kēia manawa he 10 kiloamps (kA). ʻO kēia helu helu e pili ana i ka nui loa o ke au pōkole pōkole e hiki ai i ka mea hana ke kū ma mua o ka loaʻa ʻana o ka pōʻino a hāʻule paha. Hiki ke au i ke au o ke kaapuni pōkole i loko o nā ʻōnaehana uila ma muli o nā hemahema a i ʻole nā ​​kūlana kūlohelohe, a hiki ke kiʻekiʻe loa a hiki ke luku ʻia. Ma ka loaʻa ʻana o ka mana pōkole o kēia manawa o 10kA, ua hoʻolālā ʻia ka JCRB2-100 e hoʻomau i ka hana a hāʻawi i ka pale ʻoiai inā loaʻa kahi hewa pōkole nui, a hiki i 10,000 amps. ʻO kēia hiʻohiʻona e hōʻoia i ka mea hiki ke mālama pono i ka ʻōnaehana uila a me kāna mau ʻāpana inā loaʻa nā hewa kiʻekiʻe.

ʻO ka helu palekana IP20

Loaʻa i ka JCRB2-100 Type B RCDs kahi helu pale IP20, e kū nei no ka helu "Ingress Protection" 20. Hōʻike kēia helu i ka pale ʻana o ka mea paʻa i nā mea paʻa i ʻoi aku ka nui ma mua o 12.5 millimeters ka nui, e like me nā manamana lima a i ʻole nā ​​​​mea hana.

1.He aha ka ʻano B RCD?

ʻAʻole pono e huikau nā ʻano B RCD me nā ʻano B MCB a i ʻole RCBO e hōʻike ʻia ana ma nā hulina pūnaewele he nui.

He ʻokoʻa loa nā ʻano B RCD, akā naʻe, ua hoʻohana ʻia ka leka like i hiki ke alakaʻi hewa. Aia ka ʻAno B ʻo ia ka ʻano wela ma kahi MCB/RCBO a me Type B e wehewehe ana i nā hiʻohiʻona magnetic i kahi RCCB/RCD. ʻO ia ke kumu e loaʻa ai iā ʻoe nā huahana e like me RCBO me ʻelua mau hiʻohiʻona, ʻo ia ka mea magnetic o ka RCBO a me ka mea wela (hiki ke lilo i Type AC a i ʻole A magnetic a me kahi Type B a C thermal RCBO).

2.Pehea e hana ai nā ʻano B RCD?

Hoʻolālā pinepine ʻia nā ʻano B RCD me ʻelua ʻōnaehana ʻike i kēia manawa. Hoʻohana ka mea mua i ka ʻenehana 'fluxgate' e hiki ai i ka RCD ke ʻike i ka manawa DC maʻemaʻe. Hoʻohana ka lua i kahi ʻenehana e like me Type AC a me Type A RCDs, ʻo ia ka voltage kūʻokoʻa.
