Porduct Overview

EKR3L smart RCBO offers not only overload, short-circuit, and leakage protection like traditional circuit breakers, but also the ability to be remotely controlled and monitored through the Tuya APP or RS485 platform. It also provides an automatic reclosing function to improve the reliability of the circuit power supply.

EKR3L Smart RCBO combines traditional RCBO protection features with modern smart home technology, providing users with enhanced safety, convenience, and control over their electrical systems. It is particularly useful for remote management of electrical circuits and can be integrated into broader smart homes or building automation systems.

Features

Traditional protection:

Overload protection
Short-circuit protection
Leakage protection (residual current)

Smart Capabilities:

Remote control through Tuya APP or RS485 platform
Wi-Fi, ZigBee, RS485, or Dry contact communication options
Supported Apps: Tuya, Smart Life

Advanced Functions:

Remote opening and closing control
Timing tasks (power on/off scheduling)
Real-time switch status monitoring
Optional built-in automatic reclosing function

Automatic, Manual Mode:

Automatic mode allow remote control (Tuya APP, RS485)
Manual Mode, only supports local manual operation

Mechanical Padlock:

When the mechanical lock is pulled out, the switch enters a locked state, preventing the switch from being turned on. To restore the device, press down the mechanical lock.

Applications:

Smart home systems, which can be integrated into the overall home automation solution.
Commercial buildings, which can achieve centralized energy management.
Industrial facilities, which can remotely monitor and control individual circuits.
Locations where electricity consumption requires regular control, such as billboard lighting and public area lighting.
