Product information

Description

The ORNO three-phase current transformer OR-WE-533 is designed for monitoring electrical parameters in three-phase installations with line voltages up to 440 V and currents up to 63 A. It measures and logs voltage, current and derived power values, and communicates measurement data via Tuya Smart Wi‑Fi for remote access and integration with compatible smart-home platforms. The device is intended for use in commercial and residential distribution boards where continuous energy monitoring and logging are required.

Advantages

This three-phase current transformer combines direct measurement and local logging with wireless connectivity, allowing both on-site data recording and remote monitoring through Tuya Smart-compatible apps. The unit supports simultaneous measurement of three phases, enabling accurate load analysis and detection of imbalance or unusual consumption patterns. Compact dimensions and straightforward mounting make it suitable for retrofit and new installations without major panel modification.

Suitable for

  • Monitoring energy consumption in small commercial premises and multi‑family buildings
  • Load balancing and phase imbalance detection in three‑phase electrical systems
  • Remote reading and integration with Tuya Smart Wi‑Fi home automation platforms
  • Logging and historical analysis of voltage, current and power for maintenance or energy optimization

Key specifications

  • Operational voltage: up to 440 V (three‑phase systems)
  • Rated current range: up to 63 A per phase
  • Measurement functions: voltage, current and calculated active power/energy
  • Connectivity: Tuya Smart Wi‑Fi for remote monitoring and cloud logging
  • Installation type: panel/ DIN-rail compatible or clamp mounting suited for distribution boards
  • Data logging: local recording with periodic upload to cloud via Wi‑Fi

How to use

Install the transformer in the distribution board following local electrical regulations and isolate power before starting work. Connect the three phase conductors and neutral according to the product wiring diagram and secure current sensors or clamps around each phase conductor as specified. Configure Wi‑Fi connectivity using the Tuya Smart app: put the device in pairing mode, connect to the home network and complete the setup in the app to enable remote reading and cloud logging. Verify measured values against a reference instrument after installation to confirm correct wiring and calibration.

Usage recommendations

Use the device within the specified voltage and current limits and ensure proper enclosure and protection in distribution panels. For reliable Wi‑Fi operation, place the unit where it receives adequate signal strength or use a local access point/mesh node nearby. Regularly review logged data to detect load changes or anomalies and schedule periodic inspections to ensure secure connections and correct sensor positioning.
