1. ʻO ke kiʻekiʻe o ke kiʻekiʻe (18 modulus 63A), ka mana haʻihaʻi maʻamau (4.5kA) a me ka hiki ke hoʻololi i nā lako.
2. Loaʻa i ke kolamu uwila ka pono o ka palekana kiʻekiʻe.
3.current-limiting contact system magnetic blown arc extinguishing device, e pale i nā huahana a me nā lako e kū i ka nui pōkole-circuit current, hoʻomaikaʻi i ka huahana arc extinguishing Hiki ke hōʻoia i ka hoʻomaikaʻi ʻana i ka hiki
4. ʻO ka pūpū a me nā kī hana ke ʻano o ka nylon PA i lawe ʻia mai me ka pale ahi kiʻekiʻe e pale i ka wela a me ka hopena.
5. He moʻolelo kona ʻano, kūpono kona ʻano, a he nui ka pale patent

Hoʻopili mau ʻo Yuanky i ke kumumanaʻo o ka mea kūʻai aku i ka mea nui a me ka maikaʻi ma mua, a ke nānā nei i ka hui pū ʻana me ʻoe.
