The
moving & stationary
secondary contact block frame assemblies are rugged
mounting frames for holding the secondary male and female contact block(s). These
rugged mating frames provide positive alignment between the two halves. The moving
assembly is mounted on the lower right hand side of the breaker carriage when looking
at the breaker from the rear and holds the male contact block(s). The stationary assembly
is mounted on the lower left hand rear side of the switchgear cell when looking at the cell
from the front and holds the female contact block(s).
The moving secondary block mounting frame has four large alignment devices two
Pins and two Ports (
#3
- photos above) that have their interface opposites on the
cell’s stationary coupling side. These coupling alignment Pins & Ports provide positive
positioning of the two halves as they approach and engage each other for final electrical
connection.
As the Citadel breaker is fully racked into the connected position - the two halves of the
secondary contact block assembly (moving and stationary) will automatically engage
with each other and make up the various control circuits designed into the switchgear
assembly.
Screw type terminals hold the secondary wiring securely in the contact block. Wiring is
enveloped in a flexible grounded metal mesh shroud. This provides protection and allows
the movement of the secondary wiring as may be needed.
The
moving & stationary
secondary contact block frame assemblies will have one (1)
set of secondary contact blocks as standard (
#1
- photo above) and an optional set on
the cell side when the B-MOC option is purchased (
#2
- photos above).
