澳大利亚采购需求：AFDD（电弧故障检测装置）、断路器、低压保护装置、RCBO（剩余电流动作断路器）

I'm reaching out to inquire about the certification status of your latest arc fault detection devices for the Australian market. Specifically, do these units have the necessary approvals for sale and use in Australia? Additionally, do you have an established distributor within the country to facilitate purchasing and support? I'm also interested in whether your product range includes a three-phase version, as this is crucial for my requirements. Lastly, I want to confirm if these devices come with RCD protection included, as I prefer a model without that feature. Looking forward to your detailed response on these points!
