SIRIUS 3RB2906 current measuring module for overload relays

The current measuring modules are intended for use as system components for connection to the 3RB22 to 3RB24 evaluation units. The motor current is recorded using these evaluation units and the measured value for evaluation transferred to the evaluation unit.

The current measuring modules up to size S3 are equipped with straight-through transformers and can be snap-fitted under the evaluation units. The larger evaluation units are fitted directly on to the contactor or individually fitted upright.
