ABB current transformer

The ABB current transformer CM‑CT 500/5 is suitable for precise current measurements in power distribution systems and monitoring applications. With its transformation ratio of 500/5 A, it supports the reliable acquisition of high currents while maintaining a compact design. The device enables stable measurement performance in industrial environments and is optimized for control cabinet applications. Thanks to its robust construction and clearly structured terminals, it facilitates integration into measurement and monitoring tasks, for example in combination with energy meters or power analysis systems.

• TechnologyThe transformer operates according to the classic principle of a conventional measuring current transformer and delivers a standardized secondary current of 5 A for further processing in energy metering devices. The fixed core geometry ensures reproducible measurement results and minimizes deviations under variable loads. This makes the model suitable for precise and long-term stable current measurement in low-voltage distributions.
• ConnectivityThe transformer provides a standardized 5‑A secondary output for measuring devices, energy meters, and monitoring systems. This allows it to be easily integrated into existing measurement chains. The clearly structured terminals support safe and error-free wiring, which is particularly relevant when used in complex energy management architectures.
• Mounting conceptThe compact design enables space-saving installation in the control cabinet. The device is mounted firmly around the conductor, ensuring stable mechanical alignment. The standardized dimensions make it easier to combine with additional measurement components without requiring extra space for special mounting brackets.
• CompatibilityThe current transformer is suitable for use in energy meters, monitoring modules, and analysis devices that expect a 5‑A transformer secondary current. With a rated primary current of 500 A, it can be used in typical industrial and commercial low-voltage distributions, for example in combination with modern energy meters for load monitoring.
