ABB current transformer

The ABB current transformer CM-CT 600/5 is designed for the precise detection of high primary currents and enables reliable measurement and protection technology in power distribution systems. With its compact housing and standardized dimensions, it is suitable for control cabinet applications with limited installation space. The transformer reduces high currents to a usable secondary signal of 5 A, allowing measuring devices and protection relays to be operated safely. Thanks to its robust design and straightforward integration, it is a commonly used solution for industrial power monitoring and energy acquisition.

• TechnologyThe transformer operates based on a classic inductive measurement principle and reliably transforms high primary currents into a 5 A secondary current. The solid-core design ensures stable measurement values even under fluctuating load conditions. Thanks to its standardized design, this model is particularly suitable for precise energy measurements in AC networks, where a constant, low-distortion signal characteristic is essential.
• ConnectivityThe current transformer provides a standardized 5‑A secondary output, allowing it to be integrated into common measurement and protection systems. The clearly structured terminals simplify the connection to measuring devices and ensure secure signal transmission. This makes it easy to integrate the transformer into existing energy monitoring solutions.
• Mounting conceptThe compact housing with an installation height of 79mm and a width of 61mm enables space-saving installation in the control cabinet. The solid-core construction ensures a secure fit, supporting safe cable routing. Installation is carried out in the classic manner by passing the primary conductor through the transformer, allowing for quick integration into existing installations.
• CompatibilityThe rated secondary current of 5A meets common industry requirements and allows use with standard measuring devices, energy meters, and protection relays. This makes the transformer suitable for a wide range of monitoring and protection applications in industrial power systems.
