Liebert® CROSS Chassis ensures maximum reliability to critical loads by eliminating system failures that are caused by problems in distribution rather than by the failure of the power source itself. The advanced control logic of Liebert CROSS Chassis provides the load with the highest safety through the 'break before make' (BBM) switching device which is available in any mode of operation and with any kind of load. Liebert CROSS Chassis can be fully customized according to customers’ load and environmental requirements. Available in 160-450 A, Liebert CROSS Chassis is delivered with both three-phase input and three-phase output.


  • Ensures redundant power to critical loads

  • Enables automatic transfer of the load to the priority line whenever its parameters fall within certain values

  • Maximum reliability with redundant control logic


  • Liebert® CROSS Chassis ensures redundant power to critical loads through its ability to switch between two independent alternative power sources

  • Fixed priority mode of operation: Liebert® CROSS Chassis will transfer the load to the chosen priority power line whenever its parameters fall within certain values always in accordance to the users selection

  • The no priority mode allows Liebert® CROSS Chassis to consider both lines to be equally acceptable

  • The BBM modality on both poles, ensures that the two sources will never be directly connected

  • Liebert® CROSS Chassis ensures switching between independent AC power sources in both synchronous and asynchronous conditions, relative to the input waveforms and within CBEMA guidelines Emergency switching, allowing the transfer to take place within milliseconds

  • Downstream short-circuit recognition, caused by loads or distributions
