Introducing the Omicron CMC 356

The CMC 356 is a universal solution for testing all generations and types of protection relays. This piece of electrical test equipment features six powerful current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range. As a result, the unit is 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. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using a secondary current injection from the test set.
