R7-125 series earth leakage circuit breaker ua hoʻohana nui ʻia no AC 50 Hz, helu ʻia ka uila.

230/400V, helu ʻia i kēia manawa 6A i 63A, loaʻa ka leakage uila haʻalulu, overload, pōkole kaapuni pale hana, etc. Hiki ke hoʻohui i ka hana pale overvoltage e like me nā koi o nā mea kūʻai aku; Hoʻohana nui ʻia i ke kūkulu ʻana i nā kukui a me ka pale ʻana i ka ʻōnaehana hoʻoili mana. Hiki ke hoʻonui ʻia ma lalo o ka volta, ma luna o ka hana pale voltage e like me nā koi o ka mea hoʻohana; ʻO kēia huahana e like me ka maʻamau IEC61009-1 a me GB16917.7.
