# Panel mounted circuit breaker (CBE equipment circuit breaker)

DD-Frame intelligent protection and monitoring (RMU) circuit breaker (D8)

The Intelligent Protection Device (IPD) is a monitoring unit integrated with a CBI DD-Frame circuit breaker. The IPD measures current and circuit breaker status. It transmits information via an RS-485 serial bus, enabling the host system to monitor current usage and ON/OFF/trip status. The unit features an active health monitor that enables condition-based maintenance through the storage of operational counts (load, no-load, overload, and operating environment) in memory. Each device has a unique and traceable identity through the reading of manufacturing information. Visible tri-color LEDs on the top and bottom are configurable to display various statuses.

# Panel mounted circuit breaker (CBE equipment circuit breaker)

DD-Frame circuit breaker (D7) with remote control unit (RAU)

The Remote Actuator Unit (RAU) is a factory-preset module that enables automatic opening and closing of DD-Frame circuit breakers. The RAU internally drives the circuit breaker ON and OFF. The RAU is mounted to the left of the circuit breaker and can drive up to three-pole circuit breakers. The RAU is only suitable for circuit breakers with standard operating handles. The RAU is equipped with LEDs to indicate the operating mode (PULSE or CONSTANT). Colored indicators show the position of the connected circuit breaker latching mechanism - green for OFF, red for ON. The RAU provides the option to set the drive signal voltage between pulse or constant mode - selectable via a switch on the front of the RAU.

Remote control unit (RAU) with lock - DD-Frame circuit breaker (D5)

The Remote Actuating Unit (RAU) is a factory-preset module that enables automatic opening and closing of DD-Frame circuit breakers. The RAU internally drives the circuit breaker ON and OFF. The RAU is mounted to the left of the circuit breaker and can drive up to three-pole circuit breakers. The RAU is only available with circuit breakers that have a standard operating handle. The unit has an LED that provides indication of the operating mode (remote or manual) and status. It also has colored indicator lights that show the position of the interlock mechanism of the connected circuit breaker - green for OFF, red for ON. The RAU provides the option to set the operating mode between remote or manual, selectable via a switch on the front of the RAU.
