Circuit Breaker Racking Unit - Model CBRU-EX

CBRU - Circuit Breaker Racking Unit
EX- Extractor

The Circuit Breaker Racking Unit was designed to eliminate the dangerous and arduous task of 'racking" or engaging medium to high voltage circuit breakers.

By removing the ServiceTechnician from the blast area or danger zone of the High Voltage Circuit Breaker and replacing the 'manual racking"operation with remote controlled CBRU, the risks (Blowout and Flashback} associated with engaging and disengaging HVCB's are eliminated.The picture above (right) is just one of the devastating effects that can be associated
with the racking operation
