CBRU - Circuit Breaker Racking Unit

FX - Flexi ble Drive Position

T - Trolley Mounted

The CBRU-FXT is the base unit of Jeff Hort Engineering's range of Circuit Breaker Racking Units and is designed to meet 80% of all racking requirements of High Voltage Circuit Breakers.

The CBRU-FXT can be used to rack horizontally, vertically or scissor lift actions.The CBRU-FXT has been tried and tested on a range of manufacturer's circuit breakers including: Reyrolle, GEC, Siemens, Westinghouse ABB, Hawker Sidley, Honeywell.

With the unique designed spring loaded drive head with quick release Fitting and any number of drive couplings the CBRU·FXT can meet all your circuit breaker maintenance and service requirements ....... with Safety .... the nun1ber`0lIE prlorlty.

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
