The CMC 356 is the universal solution for testing all genera and types of protection relays. Its powerful six power sources (three-phase mode: up to 64 A / 860 VA per channel) with a large dynamic range, makes the device capable of testing even high-load electromechanical relays with very high power requirements.

The CMC 356 is the first choice for applications with the highest versatility, amplitude and power. Commissioning engineers will certainly appreciate the ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
