RAU Remote Controlled MCB 0,5-300A for AC and DC applications

The CBI DD-frame is a very compact and reliable Hydraulic-Magnetic circuit breaker ideal for battery applications, power supplies and distribution of larger loads in branch protection circuits. For applications including energy storage, battery management and telecom UPS systems, it is an advantage to be able to fully control the status of the MCB; - Remotely switching to OFF and ON, as well as being able to remotely reset the MCB after an electrical fault. A CBI DD-frame can be fitted in remote areas as well as in places where it’s not necessarily easy to access the circuit breaker in the equipment but still have full control in terms of operating the MCB. Using the CBI RAU together with a CBI DD-frame in your application enables you to take your equipment to the next level in terms of remote accessibility, as well as giving the possibility to dramatically reduce maintenance cost and system down time if a non-fatal fault tripping occurs. The RAU enable easy remote control of a complete system and is a way to save cost as well as space. Traditional solutions to remotely enable on/off of a system is contactors and MOSFET solutions. These solutions are costly, require space and also create energy losses. Another benefit for the RAU solution is that you get possibility to also control the circuit breaker itself and by that get the possibility to reset the breaker after an overload or similar noncritical fault. It’s easy to imagine the benefits with this if the fault occurs at a remote location which might take hours or even days to reach. The RAU can also in a simple way maximize the usage of the battery capacity in for instance a telecom site. At a mains failure you can easily prioritize the loads and by that get best possible uptime for the most critical loads. When power is back you can then remotely switch back load by load.

The CBI RAU is a factory fitted module that enables the automated switching of the DD-frame circuit breakers. The unit can actuate the circuit breakers both ON and OFF. The actuation of the circuit breaker pole occurs completely internally. The RAU unit is mounted on the left hand side of the circuit breakers and can be connected up to a three pole unit. The RAU connects to circuit breakers with a standard toggle. The circuit breakers can be manually operated when in the remote mode. Two indicators are present on the front face of the RAU. The first is a LED that provides an indication which indicates the mode of operation as well as showing the units status. The second is a color flag indication which indicates the position of the latching mechanism of the connected circuit breakers. The unit has a select switch, providing the ability to specify the operation mode – remote or manual. A signal output provides feedback to the user that there is power on the load side of the circuit breakers. The connection of the control signal is done via a standard connection terminal block, Phoenix 1780002 or equivalent, which is included with the RAU module.

The RAU unit is powered with a DC voltage but it can also be used to control AC circuit breakers.
