Product Description

The TAXNELE TVPS3-100LW smart three-phase relay is a multifunctional device for protecting, monitoring and controlling three-phase electrical installations. The product combines the functions of a protection relay with those of a smart energy meter, offering a local LCD display and remote access through compatible mobile apps.

The device is designed for three-phase systems and allows monitoring of important electrical parameters: voltage, current, active power, power factor, frequency, temperature and energy consumption. The bidirectional metering function allows energy to be tracked in both directions, making it useful in applications where consumption and energy flows need to be monitored.

TAXNELE TVPS3-100LW offers multiple protection functions: overvoltage, undervoltage, overcurrent, undercurrent, leakage current, high temperature, voltage imbalance between phases, current imbalance, phase loss and phase sequence. Protection parameters are adjustable, while timer, countdown and remote control functions allow integration into smart home scenarios or technical applications.

The three-phase relay must be installed by an authorised electrician or qualified personnel, in accordance with the wiring diagram, applicable technical standards, the manufacturer's instructions and the requirements of the three-phase installation. Residual current / leakage current protection may require an external current transformer, depending on the product configuration.
