The modular, multi-phase CMC 500 relay test set can reduce testing efforts by up to 80% and allow for a complete validation of protection systems. It sets new benchmarks for output performance, versatility, cybersecurity, and workplace safety. With up to seven voltages (300 V each) or ten currents (30 to 60 A per channel, 450 A single-phase), the CMC 500 supports a wide range of applications, making it ideal for field use and commissioning in conventional, hybrid, and digital IEC 61850 substations.

The device is available in five variants, each compact and lightweight (12.1-15.6 kg) to suit specific needs.
