Remote Racking Operator for AKD-10
3-2 Description Large Frame Remote
Racking operator – 3200-5000A Frame
WavePro Breakers
The remote racking operator consists of a drive
train, control switches, and attachment brackets.
The drive train is made of a gear motor (1, fig 2),
a square drive socket (2, fig 2), which couples the
breaker.
Two control switches and a circuit breaker are
included with each remote racking operator.
The START switch (3, fig 2) housed in the hand-
held box (4, fig 2) controls the power to the
motor. Pushing the button closes the switch and
in turn supplies power to the motor. This control
switch is spring loaded; therefore, continuous
pressure on the button is required to keep the
motor running. The motor directional control
switch (5, fig 2) is mounted on the motor
housing. Two positions are provided , “IN” and
“OUT”. For racking toward the CONNECT
position the switch should be set in “IN”. For
racking toward the DISCONNECT position, the
switch should be set to “OUT”. The circuit
breaker (6, fig 2) senses the motor stall current
when the breaker reaches the end of its travel
which causes the motor to stall. The higher
motor stall current trips the circuit breaker to the
OFF position and in turn shuts off the power to
the motor.
The ¼ turn shaft (item 7) is designed to provide
the means for attaching the remote racking
operator to the front of the Large Frame Breaker
ATTACHMENT / REMOVING DEVICE
Attaching the Remote Racking Operator to
the Large Frame WavePro or Entellisys
circuit breaker
The circuit breaker must be in the OPEN position
before attempting to attach the Remote Racking
Operator to the breaker. Slide either the upper or
lower Racking Screw Access Cover (located on
the upper right corner of the breaker cubicle
door) to the left. This will expose two openings
in the breaker cubicle door. The upper opening is
for the ¼-turn latch rod and the lower opening is
for the square drive coupling. Position the
Remote Racking Operator so that the square
drive coupling and ¼-turn latch rod are aligned
with the openings in the breaker cubicle door.
Push the Remote Racking Operator toward the
breaker so that the square drive coupling engages
the square racking shaft and the ¼-turn latch rod
engages the breaker frame. If the coupling and
the shaft are not in alignment, the motor shaft
extension on the back of the motor housing can
be rotated in either direction until the square
drive aligns with the square racking shaft. When
they are in alignment, the Remote Racking
Operator will slide further through the breaker
cubicle door. Rotate the ¼-turn latch rod
counter-clockwise to lock the Remote Racking
Operator to the breaker.
Removing the Remote Racking Operator from
the Large Frame WavePro circuit breaker
Hold the Remote Racking Operator securely and
rotate the ¼-turn latch rod clockwise to release
the Remote Racking Operator from the breaker.
Pull the Remote Racking Operator away from the
breaker cubicle door. The Racking Screw Access
Covers will close automatically.
