The Fixed Mounted Citadel was developed to maximize ease of conversion of older
breakers.
In order to maintain (or upgrade) the original breaker so that it incorporates “trip free”
racking and “close-spring discharge”; the Citadel is provided with assemblies that
access the trip and close linkages. Both are easily accessed via extension rods.
The extension rods are located at a convenient point, extending through the lower right
hand bottom of the breaker’s mechanism enclosure. Each extension rod comes with
threaded inner diameters to accept an M6 bolt.
NBS takes no responsibility nor warrants the interface connections provided by any
breaker conversion company between the original breaker’s “trip free”, & “spring
discharge” systems, and those of the Citadel.
When the Citadel mechanism is held mechani-
cally tripped, the main contacts of the vacuum
interrupters briefly touch (kiss) as the breaker
goes through a close/trip cycle.
DANGER
It is imperative that the Citadel element is not
allowed to have its contacts briefly touch (kiss)
while it is being racked off the main voltage
primary connections.
