Product Profile
Product Profile
DRAFT package — pending confirmation. PDF type code lists communication method 5 = RS485, but all product appearance photos are printed as EKR0 WiFi with Tuya badge and antenna. Do not treat gallery photos as dedicated RS485 hardware photos until confirmed.
EKR0 Smart RCBO combines the functions of traditional circuit breakers with modern electronic technology to provide overload, short circuit, and leakage protection for circuits rated at 63A. It also supports remote control through the RS485 communication platform, allowing monitoring and adjustment of various electrical parameters. The EKR0 Smart RCBO has been widely used in smart building power management, industrial power monitoring, and energy efficiency optimization.
This draft page is for the RS485-only communication variant of EKR0 (type code communication method: 5).
