ABB current transformer

The ABB current transformer CM‑CT 200/5 is used for the precise measurement of alternating currents in systems with external transformer metering. Its compact housing with low installation depth makes integration into existing control cabinets easier. With an output current of 5 A, it supports standards‑compliant downstream processing in energy meters and monitoring systems. The transformer is suitable for industrial environments and technical infrastructures where reliable current measurement is required for protection and evaluation functions.

• TechnologyThe CM‑CT 200/5 is based on a classic closed iron core and provides stable conversion from 200 A primary current to 5 A secondary current. This technology ensures a consistent measurement characteristic and reduces measurement errors under typical grid loads. Thanks to its compact design, electromagnetic stray fields remain low, supporting clean signal transmission.
• ConnectivityThe transformer provides a standardized 5‑A secondary output that is used for common energy meters, evaluation modules, and monitoring systems. This interface enables low‑loss and standards‑compliant transmission of measurement signals, allowing the CM‑CT to be easily integrated into existing measurement chains.
• Mounting conceptWith its compact dimensions, the current transformer is suitable for narrow control cabinets and can be mounted directly around the conductor to be measured. The robust housing design ensures secure fixation and minimizes the influence of vibrations. The design supports fast installation without additional mechanical effort.
• CompatibilityThe CM‑CT 200/5 is designed for measuring devices that support a 5‑A input, including energy meters, power analyzers, and protection devices. It is suitable for a wide range of industrial applications where precise current measurement is required.
