    Manual 2. Product Description 2.1. Description of the Communication Module The EB-MODBUS-RTU communication module serves as an interface for connection to a higher-level controller and is compatible with circuit breakers of the variants EB-08, EB-18, and EB-38. To ensure error-free operation, the maximum number of 40 circuit breakers must not be exceeded.
