Core Features & Project-Focused Advantages

Multi-Protocol Compatibility for Seamless Industrial System Integration

Unlike standard smart circuit breakers, this ZigBee DIN-rail MCB supports multiple communication protocols including Tuya ZigBee, Tuya WIFI, RS485, and dry contacts, enabling seamless integration with existing industrial control systems, building management systems (BMS), and third-party automation platforms. This flexibility makes it the ideal choice for complex industrial projects requiring cross-system linkage and centralized control.

High-Speed Circuit Protection & Customizable Auto-Reclosing

Engineered for industrial-grade safety, the device features a 6KA breaking capacity, with tripping time ≤0.1S and short circuit response time ≤0.04S, delivering instant protection against circuit faults to prevent equipment damage and electrical hazards. It also supports customizable automatic reclosing, with adjustable reclosing time settings, to restore power automatically after transient faults, minimizing downtime for critical industrial operations and reducing on-site maintenance intervention.

Scalable Design for Bulk Industrial Deployment

With standard DIN-rail mounting and a compact 2P form factor, the auto-reclosing smart MCB fits seamlessly into standard industrial distribution cabinets, supporting bulk installation in manufacturing plants, large commercial buildings, and infrastructure projects. It supports customizable protection thresholds to match diverse industrial load requirements, with a wide rated current range (10A to 63A) to adapt to different power distribution scenarios.

Product Operate Guide

Optimized for fast on-site deployment by engineering teams, the ZigBee smart MCB installation and pairing process follows these streamlined steps:

Download and install the Tuya Smart APP, register and log in with your project management account, and ensure your ZigBee gateway is online and connected to the same network as your mobile device.

Complete wiring per the official schematic: connect upper terminals to the main power supply and lower terminals to the load, then power on the device and confirm the LED indicator is active.

10 seconds after power-on, press and hold the pairing button until the status indicator flashes, confirming ZigBee pairing mode activation.

In the Tuya APP, click the "+" icon in the top right corner, select the "Circuit Breaker" device category, and choose the ZigBee MCB option to enter the pairing interface.

The app will automatically detect the device via the ZigBee gateway; follow the on-screen prompts to complete the network connection.

Wait for the pairing process to finish, then set a project-specific device name and label.

Configure custom protection parameters and control rules as required for your project, then complete deployment.

FAQ

Can this MCB integrate with our existing industrial BMS via RS485 protocol?

Yes. The RS485 compatible smart MCB natively supports RS485 communication, along with dry contact and ZigBee protocols, enabling seamless integration with most mainstream industrial building management systems, PLC control systems, and third-party automation platforms for custom project requirements.

How does the auto-reclosing function work for industrial applications?

The device’s customizable auto-reclosing function can be configured with specific reclosing times and retry counts based on your project needs. After a transient fault (such as a temporary overvoltage event) triggers a trip, the device will automatically reclose after the set delay, restoring power without on-site manual intervention, while locking out and sending an alarm for permanent faults to ensure safety.
