Multi-functional Smart Metering RCBO MT61GR

MT61GR

The MT61GR Multifunctional Smart RCBO is an all-in-one electrical safety and management solution. It provides the same advanced features as the MT61GP—including high-precision energy metering and remote control—with the added critical layer of Residual Current Protection (Leakage Protection). This device is digitally implemented via an MCU and features an integrated design that eliminates the need for external CT wiring, saving space while offering comprehensive protection against overvoltage, overload, and leakage. With its ability to perform automatic reclosing after nuisance trips, the MT61GR is ideal for ensuring safety and power continuity in smart homes, telecom stations, and renewable energy sites.

All-in-One Integration

Integrates metering, protection, auto-recloser, remote control, and residual current protection (different from the MT61GP) into a single unit, eliminating the need for separate professional wiring and saving significant cabinet space.

Advanced Metering 

• Bi-directional Tracking: Measures both imported and exported energy, perfect for solar/wind applications.
High Accuracy: Offers Class 0.5 accuracy for voltage/current and Class 1.0 for active energy.
• Multi-Tariff Support: Features a 4-tariff system to optimize energy costs across peak and off-peak hours.
• Detailed Data: Monitors power factor, demand, and phase angles.

Intelligent Control

• Remote Operation: Supports remote opening and closing via standardized Modbus RTU protocol as well as App and software platform.

Versatile Communication: Standard RS-485 port with optional GPRS, WiFi, or 4G connectivity.

Real-time Feedback: LED indicators show network and device status at a glance.

Programmable Logic: Enables remote trip/close functions for energy fee management.

Reliable Reclosing

Auto-Recovery: Automatically recloses after temporary faults to minimize downtime.

•Smart Logic: Distinguishes between nuisance trips and permanent faults to protect the system.

•Reduced Maintenance: Decreases the need for manual on-site resets in remote locations.

Integrated Design

•All-in-One Unit: Combines metering, CT, recloser, and breaker to save 50% cabinet space.

•Simple Installation: Standard DIN-rail mounting with no external CT wiring required.

•LCD Interface: Features a clear graphic screen and 3-button menu for easy local setup.

Enhanced Safety 

•Total Protection: Guards against over/under voltage, overload, phase loss, and residential current protection.

•Maintenance Lock: Includes a physical "Safe Operation Lock" to protect personnel during service.

•Fault Logging: Stores the last 20 fault events with timestamps and cause analysis.

•Industrial Build: Features 6kA breaking capacity and V0 flame-retardant housing.
