Smart Circuit Breaker


MT61-GP is an integrated system of smart meters, breakers, and communications.
• Electrical parameter monitoring
• Full Protection
• Prepaid metering function with AMR
• Billing system and online payment
• Bidirectional Communications
• Remote control and remote lock
• Tamper event detection, recording, and reporting
• Power event alarms
• Current is up to 80A





Individual Device


This system is a kind of "all-in-one device", which integrates smart meter breakers, protection, remote control, communication, etc. It includes single-phase two wires and three phases four wires, and the rated current is up to 100A. Based on MT61GP smart circuit breaker, we developed a system called "Smart Power Management Platform" which is mainly used for smart electrical safety, metering and billing management, and smart power monitoring management.


Minimum Space Requirement


Compared to traditional 2P and 4P MCB, it only has an extra controller of 36mm width.


Easy to Installation


The device can be mounted in 35mm Din Rail very easily and individually.




Active and reactive energy metering (accuracy: class 1.0) Respective Measurement of Forward / reverse active energy (Programmable)


Maximum demand (MD) Measurement


Multi-tariff Measurement: 4 tariffs (Sharp, Peak, Flat, Valley) and 24-hour shifts & automatic Switch to the other standby tariff 12 monthly billings record (data item programmable)


7 digits


Data Frozen: daily, weekly, monthly, and quarterly data frozen and transferred to the cloud server


Strong Anti-tamper Functions: Electricity theft detection, terminal cover locked, and alarm for opening meter box door


Full Protection


This system includes all the protections: Overload, Short Circuit, Over/Under Voltage, Phase Loss, Unbalance, High-temperature




RS485, GRPS2G/3G, NB-IoT




Modbus and MQTT


Electrical Faults Analysis


The device may realize the real-time analysis of all electrical faults: short circuits, earth leakage, overload, over/under voltage, and overheated.


Monitoring in Real-time


The device may make realize real-time monitoring of electrical circuit parameters: Current, voltage, active Power, reactive power, Power factor, Frequency, Temperature


Over/under voltage value and over current protection value limit


The over/under voltage value and over current protection value can be adjustable through a software platform.
