Entellisys Low Voltage Switchgear
Chapter 7. Operating the Switchgear
Drawout Operation
All breakers are supported on the drawout rails mounted on
the sidewalls of the breaker compartments. On EntelliGuard
breakers, two wheels on each side of the breaker rest on each
drawout rail.
Motion is provided by a mechanism mounted on the breaker.
This mechanism drives racking cams that engage pins
anchored to each side of the compartment.
The cams are driven by a removable racking handle that
engages the mechanism. On small frame breakers, the
handle is inserted through an opening in the breaker
escutcheon; on large frame breakers, the handle is inserted in
an opening in the upper right side of the door.
Turning the handle in a clockwise direction drives the
breaker into the compartment. As the breaker disconnect
fingers engage the stationary studs, a high force will be felt.
Turn the racking handle as far as it will go to be sure the
disconnect fingers are completely engaged.
The position indicator in the breaker escutcheon gives the
position of the breaker as it moves through the door cutout.
