The CMC 356 is the universal solution for testing all generations and types of protection relays from the oldest electro-mechanical relays to modern IEC 61850 based IEDs. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. The flexible software allows the testing of all types of relays, i.e. basic over-current and earth-fault relays (non-directional or directional), complex motor protection relays and/or sophisticated power transformer differential relays or feeder distance protection relays.
