Porduct Overview

EKR3S Smart MCB offers overload and short-circuit protection for circuits up to 100A, and can also monitor various electrical parameters in real-time, with remote control capabilities through the Tuya APP or RS485 platform.

EKR3S 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
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, Electricity metering (only 1P&2P)
Automatic, Manual Mode: Automatic mode allows 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.
