Porduct Overview

EKR3 smart MCB provides not only overload and short-circuit protection like traditional circuit breakers, but also the ability to remotely control the closing and timing of the MCB through the Tuya APP or RS485 platform, as well as obtain the switch status of the device.

EKR3 smart MCB is an ideal choice for smart home and industrial automation systems, offering circuit protection, remote control, and monitoring capabilities to improve energy management efficiency, enhance power safety, and provide users with more control options.

Features:

Traditional protection: Overload protection, Short-circuit protection
Multiple communication methods: WiFi (Tuya), ZigBee (Tuya), RS485, Dry Contact
Advanced functionalities: Remote closing and timing control of the circuit breaker, Real-time switch status monitoring
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.
