CMC 356 Universal relay test and commissioning tool set.

​

 To test each type and generation of protection relays, the CMC 356 is the universal solution. It has six powerful current sources (three-phase mode: up to 64 A/860 VA per channel) and has an exceptional dynamic range. These advantages ensure that the unit can test even high-load electromechanical relays with exceptionally high power requirements.

 The CMC 356 is the main choice for applications that require the greatest amount of power, amplitude and versatility. Its ability to perform wiring and plausibility checks or current transformers is priceless for commissioning engineers. It does this using a primary injection of high currents from the test set.
