Inspection
Thoroughly inspect the sectionalizer for visible damage. Do not install the sectionalizer if there is damage
to any of the parts.
Storage
If the sectionalizer will not be installed immediately, it must be stored in a clean, dry location at ambient
temperatures from -40°C to 85° C.
Installation
Select a properly rated sectionalizer for each installation with consideration to continuous current,
actuating current, BIL, and number of counts. If applicable, ensure the nameplate rating for continuous
current and counts matches the applications requirements. Should there be any concern on the use of
this sectionalizer as rated, consult your supervisor BEFORE installation.
Securely attach mounting bracket to crossarm or pole. Install the sectionalizer mounting assembly on
the mounting bracket with the external tooth lockwasher placed between the mounting bracket and the
sectionalizer bushing support pin (see Figure 1). Tighten the nut finger-tight. Locate the sectionalizer on
the mounting bracket to provide maximum clearance for the operator and to provide maximum ease of
operation. Securely tighten the carriage bolt nut.
To attach electrical leads to the top and bottom terminals, loosen the nuts on both terminals, wire brush
the conductors, and apply a coating of oxidation inhibitor to both leads. Insert leads into terminals and
tighten nuts to approximately 20 lbf (Nm)

Operation & Resetting
In the event of a permanent fault, the sectionalizer will operate and drop open to isolate the faulted section
of line. Always repair the fault and reset the sectionalizer before placing the sectionalizer into service.
All resettable sectionalizers can be reset by using an adjustable wrench. Insert the opening of the
adjustable wrench into the hole on the back of the trunnion as shown in Figure 2. Rotate the trunnion with
the wrench until the trunnion is completely latched as shown in Figure 3. Slowly, remove the wrench from
the trunnion. The trunnion* will snap open if it is not fully closed. If this should occur repeat this step.
All resettable sectionalizers manufactured after March 2015 also include an “in-air” resettable
trunnion* which may be used to reset the CRS/PRS units in the cutouts. To do so, insert the hookstick,
press the sectionalizer downward and backward towards the pole, and then replace it into the cutout
between the top and bottom contacts. If the pin is not reset, the unit will not fit nor stay in place within the
cutout, i.e., it will drop out. If this occurs, please repeat the aforementioned steps to reset it. (see Figure 4).
The resettable sectionalizers are not loadbreak devices. The sectionalizer must be opened using only
approved loadbreak type tools or a similar device designed for use with cutouts. Follow all instructions
provided with such tools. The sectionalizers are equipped with “hooks” for use with these types of
loadbreak tools.
*If the device is fitted with an 'in-air' resettable trunnion, it will have a yellow donut-shaped sticker around the top potted portion. The
sticker is reflective such that if the unit drops out at night, a lineman can shine a flashlight at it and see that the unit is 'in-air' resettable
and does not need to be removed from the cut-out before being put back in service.
Ensure trunnion is latched.
Sectionalizer will not function if trunnion is not latched properly.
Follow recommended latching procedure in this manual.

To close the sectionalizer for the first time, or after properly repairing a fault, insert a hook stick into
the opening in the trunnion and place the sectionalizer module into the hinge as shown in Figure 5.
Remove the hook stick. Position yourself to the side of the sectionalizer. Place the hook stick in the
hook stick ring and rotate to the position shown in Figure 6. Look away from the sectionalizer and
quickly and firmly push the sectionalizer into the closed position. Remove the hook stick from the ring
carefully to avoid opening of the sectionalizer.

Operation Considerations
To ensure PRS devices operate on the first count, 5 Amps load or more is required to be on the line.
This ensures that all capacitors to fire the solenoid, hold counts, and record counts are fully charged.
Additionally, please be conscious of any downline devices (capacitor banks, generators, etc.) that could
cause backfeed on the line. If this backfeed exceeds 500mA (200mA for CRS), the sectionalizer will not
increment its count since the deadline condition is not met. The device must see an actuating current
(fault) for 1 cycle and deadline condition of 500mA (200mA for CRS) for 5 cycles in order to increment its
count and subsequently dropout if all counts are met.
Maintenance
All sectionalizers are tested at the factory prior to shipment. The mechanism for this device is
sealed from the environment and is not user-serviceable. Replace any modules that show evidence of
excessive pitting or burning. Replace any broken or cracked porcelain, polymer, and/or arc chute if it is
damaged. Inspect all contacts for evidence of excessive pitting or burning due to arcing and replace if
necessary. Check that the pivot of the trunnion is clean and that the trunnion moves freely when resetting
the trunnion. The trunnion and/or internal mechanism, if damaged, can be replaced at the factory.
If additional information is needed, contact your Hubbell Power Systems Representative or
HPS Customer Service at [phone] or email at [e-mail].

Notes
• The suggested actuating current of the sectionalizer should be 80% of the minimum trip value of the
upstream recloser. Where hydraulics are used, this value is 1.6 times the continuous current rating of the
recloser.
• The count to drop out MUST be at least 1 operation less than the number operations to lock-out of the
upstream recloser.
• The reset time of the sectionalizer should be greater than or equal to the reset time of the upstream
recloser.
• Sectionalizers showing as hardware revision '1' include modifications to the control board which allow
for an increased hold up time of 900 seconds. Older boards having hardware revision '0' have a hold up
time of approximately 90 seconds.
• Sectionalizers showing a hardware revision of '1' have a power up time (from a dead state) of
approximately 3.5 cycles (60 milliseconds) plus 0.5 additional cycle to increment the count and charge
the firing capacitor at 300A fault current. Older boards showing a hardware revision of '0' have a power
up time (from a dead state) of approximately 9 cycles (150 milliseconds) plus 1.5 additional cycles to
increment the count and charge the firing capacitor at 150A fault current. *Note that higher fault values
decrease the charge times of the firing capacitor and lower fault values increase the charge times of the
firing capacitor; however, the power up times are hardware dependent.
• When operating on a fast curve with lightly loaded lines, please consider setting the sectionalizer to 2
counts less than the upstream recloser if there is insucient time for the sectionalizer to power up and
increment its count.
