Ma ke ʻano he mea hana palekana uila ʻoihana, hoʻolauna ʻo YUANKY i ka KNL6-63 Series Residual Current Circuit Breaker (RCCB), kahi mea palekana kiʻekiʻe i hoʻolālā ʻia e pale i nā limahana a me nā ʻōnaehana uila mai nā haʻalulu uila a me nā pōʻino ahi i hoʻokumu ʻia e nā kahe leakage. Loaʻa i kēia RCCB 2-pole kahi volta hana i helu ʻia o 230/400V, ke au inoa a hiki i ka 63A, a me ka hiki ke haki pōkole o 10kA, e hāʻawi ana i ka hana paʻa a hilinaʻi no nā noi ʻoihana, kalepa a me nā hale noho honua.

Ma muli o ke Kānāwai o kēia manawa ʻo Kirchhoff, hana ka KNL6-63 me kahi Core Balance Current Transformer (CBCT) kūloko e nānā i ke kaulike o ke au i loko o nā uea ola a me ke kūlike ʻole. Ma lalo o nā kūlana maʻamau, ua like nā au e komo mai ana a me nā au e puka ana; ke loaʻa kahi hewa leakage (e laʻa, ka insulation i hōʻino ʻia a i ʻole ka hoʻopili ulia pōpilikia), hoʻāla ke kaulike ʻole o ke au i ka hāmeʻa, kahi e holo koke ai i loko o ≤0.1s (≤0.04s ma 5 × IΔn) e ʻoki i ka mana. ʻO kahi pihi hoʻāʻo i kūkulu ʻia e ʻae i ka hōʻoia maʻalahi o ka hana, e hōʻoiaʻiʻo ana i ka hana hilinaʻi lōʻihi.

Kūlike me nā kūlana honua e like me IEC 61008, CE a me SIRIM, kākoʻo ka KNL6-63 i nā pae ʻike he nui (30mA, 100mA, 300mA, 500mA) e hoʻokō i nā koi mākeke like ʻole. Hoʻomaʻalahi kona hoʻolālā modular liʻiliʻi i ka hoʻokomo maʻalahi ʻana i nā papa hāʻawi, ʻoiai ʻo nā mea insulation kiʻekiʻe e hōʻoiaʻiʻo i ka lōʻihi i nā wahi ʻino. Hoʻohana nui ʻia i nā hale noho, nā hale kalepa, nā mīkini ʻoihana, nā keʻena hāʻawi mana a me nā ʻōnaehana solar, he hopena palekana hilinaʻi ia no nā hoa honua, e kōkua ana iā lākou e hoʻokō i nā kūlana palekana ʻāpana a loaʻa ke komo ʻana i ka mākeke.
