NexBlue Zen Current Sensor 3P 80A

The NexBlue Zen Current Sensor 3P 80A is a three-phase current sensor for installers of EV charging installations. It continuously measures energy consumption within the installation and uses these measurements to adjust the charging power of connected charging stations, supporting dynamic load balancing so that the grid connection is not overloaded.

The module supports multiple charging points and can operate locally and through the cloud within a load management system, so charging sessions continue when an internet connection is temporarily unavailable. It can also monitor solar installations so that available solar energy can be used for charging electric vehicles. Intended applications include commercial sites, apartment complexes and larger charging installations.

The module mounts on a DIN rail in the distribution board and includes current transformer (CT) clamps for current measurement. Listed specifications include a supply voltage range of 85–264 VAC, power consumption of 3 W, and communication via RS485, LAN, WiFi, Bluetooth and RF. It is suitable for TT, IT and TN networks.
