ZAPTEC Sense (Max 60) 3-Phase Bundle with 600A Split-Core CTs (ZM000829)

Dynamic load balancing and energy monitoring for high-capacity three-phase EV charging installations require precise current measurement at the main distribution board. The ZAPTEC Sense (Max 60) 3-Phase Bundle addresses this by providing a DIN-rail mounted sensing unit and three split-core current transformers with a 60 mm aperture, rated for up to 600 A. It communicates with Zaptec Pro and Zaptec Go chargers via Powerline Communication (PLC), enabling automatic adjustment of charging current to prevent overloads and optimize energy use.

Who is it for

Electricians and installers setting up Zaptec charging systems in residential or commercial buildings with three-phase power and high current capacity (up to 600 A). It is essential for installations where dynamic load balancing is required to protect the main fuse and ensure efficient charging across multiple vehicles.

Main features

• Measures current on all three phases with 600 A split-core CTs, suitable for cable diameters up to 60 mm.
• Communicates with Zaptec Pro and Zaptec Go via Powerline Communication (PLC) for real-time load management.

Tips

Ensure the current transformers are installed around the main incoming cables before the distribution board, and verify that the Zaptec charger firmware is up to date for optimal PLC communication. For installations with longer cable runs, consider using RS485 or Ethernet for reliable data transmission.
