The TUYA Smart Energy Sensor 3P+N 63A Modbus RS485 HS083854 is an advanced device engineered to track energy consumption effectively and accurately in three-phase systems with a neutral wire, while also being applicable to single-phase setups. This smart energy sensor provides real-time measurements of essential electrical parameters including voltage, current, power, electricity consumption, and frequency. Designed for industrial, commercial, or larger residential installations, it allows simultaneous monitoring of multiple phases or individual circuits, ensuring comprehensive power management and seamless integration into automated energy systems.
Advantages
The device delivers high measurement accuracy with an energy measurement accuracy of 1 percent, meeting Class 1 standards. Supporting a current measurement up to 63A, it enables reliable monitoring of energy consumption across demanding electrical circuits. The integrated Modbus RS485 communication interface utilizing the Modbus RTU model ensures stable and fast data transmission compatible with industrial control systems and large facilities. Additionally, the sensor can analyze phase balance in three-phase systems and compare parameters of multiple circuits. Its flexible installation configuration allows placement after a main circuit breaker, fuse, or distribution panel without occupying DIN rail space.
Suitable for
- Industrial and commercial electrical installations
- Larger residential energy monitoring systems
- Real-time electrical parameter tracking of voltage, current, and frequency
- Three-phase with neutral (3P+N) and single-phase system integration
- Automated energy management systems utilizing Modbus RS485 communication
The device may not be suitable for installations where electrical currents exceed the nominal limit of 63A or in environments lacking protection against moisture, as it features an IP20 protection class. It is also unsuitable for placement before a main circuit breaker or fuse, or downstream of control devices such as contactors, variable frequency drives, or motor starters, where electrical faults, voltage pulses, harmonics, or instantaneous current surges could damage the unit.

The TUYA Smart Energy Sensor must be installed in a dry location or inside special protective boxes if moisture exposure is possible. Mount the device downstream in the electrical circuit, specifically after a main circuit breaker, fuse, or distribution panel, to monitor specific circuits or devices accurately. Ensure the wiring respects the measuring cavity diameter and that the communication interface is correctly connected to your Modbus RTU network for reliable data transmission and real-time monitoring.
What to consider before purchase
- Verify that your electrical system maximum current does not exceed the 63A nominal limit of the device
- Confirm compatibility with Modbus RS485 communication protocols for your automation setup
- Check that the installation environment is dry or equipped with appropriate protective enclosures
- Ensure proper downstream placement location after circuit protection devices
For optimal performance and safety, always install the TUYA Smart Energy Sensor 3P+N 63A Modbus RS485 in dry conditions downstream of main circuit breakers or fuses, avoiding placement near motor starters or variable frequency drives to prevent damage from current surges.
