In a world where electrical safety and reliability take precedence, the Janitza RCM 202-AB stands out as one of the most advanced and reliable tools. Specifically designed for measuring and monitoring differential currents in grounded AC systems, such as TN and TT systems, this digital DIN rail meter ensures the integrity of your installations.
What truly sets the device apart is its ability to analyze differential currents via up to two connected current transformers while simultaneously monitoring the transformer connection for any wire breaks or short circuits. The device, which complies with the IEC 62020 standard, monitors differential currents of both type A and type B, providing optimal protection against ground faults.
For businesses in critical sectors such as hospitals and the process industry, the ability of the RCM 202-AB to continuously monitor ground fault currents is invaluable. Early detection of unwanted currents can prevent costly damage to machinery and avoid risky situations that could even lead to fires.
This high-tech differential current monitor is not only efficient but also extremely user-friendly. With easy installation and full integration with the GridVis® software via the serial RS485 interface, the device enables continuous monitoring.
Key features of the RCM 202-AB:
- Monitoring of differential currents in grounded AC systems (TN and TT systems)
- Compliance with the IEC 62020 standard
