概述
The current measuring modules are designed as system
连接到3RB24评估单元的组件。使用
这些评估单元测量了电动机电流，并
measured value sent to the evaluation unit for evaluation.
The current measuring modules in sizes S00 to S3 up to 55 mm
wide are equipped with straight-through transformers and can
be snap-fitted under the evaluation units. The larger evaluation
units are installed directly on the contactor or as stand-alone
单位。
