GE Industrial Solutions Remote Racking Operator: Low Voltage AKR Circuit Breakers - Manual (Page 3)

Remote Racking Operator for AKR Breakers
3
Section 1. Introduction
The remote racking operator allows the user to
move a drawout circuit breaker between the
CONNECT, TEST, and DISCONNECT positions via
an electric racking motor and gearbox attached
to the front of the breaker. The remote racking
operator requires 115Vac, 50/60Hz control
power. A control box connected to the operator
with a thirty-foot cable permits control from a
remote location.
Prior to the initial use of the remote racking
operator, a one time modification must be
made to each breaker and breaker
compartment door.
The remote racking operator is portable and is
designed for attachment to the AKR Low
Voltage Circuit Breaker in AKD-8 Switchgear.
For all AKD-6 applications, contact a GE
Distributor.
Section 2. Receiving, Handling and Storage
2-1 Receiving and Handling
Each remote racking operator is carefully
inspected and packed for shipment. Immediately
upon receipt of the device, an examination
should be made for any damage sustained in
transit. If damage or rough handling is evident, a
damage claim should be filed immediately with
the transportation company, and the GE
Distributor should be notified.
The device should be removed from the shipping
box with sufficient care so that no damage will
result from rough handling. “Loose parts”
associated with the apparatus may be included in
the box. Care should be taken to make certain
that these parts are not overlooked. The shipping
box will include the remote racking device, two
couplers, two mounting brackets, and one
mounting plate to be used with AKR 30/50
breakers only.
The bracket for the AKR 30/50 breaker has a long
shaft that is welded to it while the bracket for the
AKR 30S, 75/100 and 125 breaker has a short
shaft welded to it as shown in Figure 1. Remove
the two wing nuts and washers that are attached
to the motor. Align the two holes in the bracket
with the studs on the racking motor. Reattach
and tighten the two washers and wing nuts to the
motor. Assemble the support plate to the AKR
30/50 bracket only by using the ¼-20 hardware
that was supplied and tighten.
2-2 Storage
The remote racking operator should be protected
against condensation, preferably by storing it in a
warm, dry environment at moderate
temperatures such as 40 degrees F to 100
degrees F. The storage area should be clean and
contain no corrosive gasses.
If the device is stored for any length of time, it
should be inspected prior to use to insure its
proper mechanical and electrical working
condition.
