CRS - (Citadel Racking System ) - Son of DH-P
(Patent pending)
The Westinghouse DH-P circuit breaker produced at the fabled East Pittsburgh switchgear
works had a unique and ingenious racking device that allowed the breaker to fully rack in
or fully rack out and then the racking screw would simply Spin Free. This provided positive
feedback to the Operator that the breaker was in its final and correct position and insured the
switchgear could not be damaged by over racking in either direction.
The Citadel breaker and switchgear improves on this exceptional safety concept by improving
the ruggedness and simplicity of the parts required for this feature to operate.
Once a Citadel breaker is fully racked in or fully racked out – the racking screw will simply
spin free.
(Kirk type) Key Lock (Optional)
On the very front / center floor of the Citadel switchgear can be optionally mounted a bracket
that operates with a key type lock (or a pad lock).
Manually rotating the bracket in the UP position allows operating personnel to turn the key-
lock and extend a lock bolt that will hold the bracket up or insert a hasp lock that will provide
the same “lock in place” functionality. In the UP position the bracket negates the ability to
insert the racking tool, thereby locking the breaker in place.
