1.0 Installation
DANGER!
Ensure that the breaker to be serviced matches the breaker listed. If the breaker to be
serviced does not match, please call CBS ArcSafeTM for more information regarding remote
switching applications for your particular model of breaker.
1. Prior to installation, inspect the breaker to be remotely operated. Please note the style of the
vents located below the breaker’s charge/close arm. Two styles of vents are shown here:
2. Identify which style of vents are present on the gear to be remotely operated, either style “A”
or “B”. The RSA-104 comes configured for Style A type vents. However, if Style B type vents
are present, the actuator can be adjusted to accommodate these as well.
3. To install the RSA-104 Remote Switch Actuator (RSA), first ensure that the handle adapter
attached to the RSA’s motor is properly aligned with the breaker’s charge/close handle
position.
4. Next, insert the two lower locating tabs located on the bottom side of the RSA into the vents as
shown. NOTE: For Style B type vents, the tabs will be located to fit one set of vents to the
right.

5. Rotate the actuator toward the handle, ensuring that the locating tabs are still secure. Place
the handle adapter over the breaker’s handle and continue to rotate the actuator onto the
breaker as shown.
6. Insert the two upper locating tabs into the vents and lock the magnet into place by rotating the
handle 180° clockwise.
ATTENTION!
The location of certain items such as mimic bus, stickers, and/or placards may interfere with
the installation of the RSA. These items may need to be removed or repositioned for proper
RSA installation.
7. Next install the threaded locking hook. Loosen the locking collar and use the locating collar to
insert the hook through the vertical vent and rotate 180° so that the hook is facing downward.
To tighten, hold the locating collar in place and turn the locking collar clockwise until the hook
is secured against the inside of the breaker.
8. Lastly, install the trip solenoid assembly so that the head of the solenoid is positioned roughly
in the center the hole as shown. Secure the assembly to the cabinet by rotating the handle of
the attached magnet 180° clockwise.
9. The RSA-104 unit is now ready to operate.

2.0 Operation
1. Ensure that the unit is properly installed on the circuit breaker as described in Section 1.0 and
that the charge/close arm is in the up position.
2. Install the 3 pin twist style connector from the RSO-III onto the motor control box and install
the 4 pin threaded connector onto the trip solenoid assembly.
ATTENTION!
Please ensure that all cables are clear of moving parts. Failure to do so could damage cables
and/or actuator.
3. This RSA was tested on a fully maintained and functioning breaker within the CBS ArcSafe
facility. During this testing the optimum settings for closing the breaker were found and
recorded on a placard located on the RSA. Please refer to these settings when setting the “#
Strokes”, “T1”, and “T2”.Once the timing is correctly set, the unit is now fully operational and
ready to use.
DANGER!
These settings may or may not apply to your breaker exactly as listed. These settings are only a
starting point for remote operations. If during the operation the desired effects are not
achieved, these may be adjusted.
4. Power on the RSO-III.
ATTENTION!
Please ensure that either the batteries on the unit are fully charged or the unit is plugged into
AC power.
5. Press the “CHARGE/CLOSE” button to actuate the breaker arm downward to close the breaker.
DANGER!
Built onto the RSA-104 there are 2 microswitch stops that prevent the RSA handle adapter from
over rotating. However, these are not meant to make the applicable settings obsolete, they
are simply in place to stop the motion of the actuator for small amounts of over-travel and may
be adjusted to achieve optimum results on the gear being operated.
6. The breaker is now able to be tripped. Press the “TRIP”button located on the RSO-III faceplate
to open the breaker.

*Ensure that personnel using this equipment are adequately trained in the operation
of the switchgear they are planning to work with; that they are correctly stationed
outside the arc flash boundary; and that they comply with all applicable Federal,
State, Local, and In-house safety regulations and procedures. Attention should be
given to distance, angle, and personal protective equipment (PPE).
