The KF86P protection relay tester and KFA300 handheld mini relay tester, recommended by Kingsine Electric ,utilize innovative technologies. They make full use of space and finely distribute the structure of each module. For after-sales maintenance, only module replacement is required, and there is no need for accuracy calibration after module replacement. Once assembly is complete, it can be used directly, truly achieving "Plug and Play".

Innovative“Plug and Play ”After-sales service advantages：

• Simple structure, beginners can achieve independent installation.
