SPEAR™ Single-Phase Recloser System
INSTALLATION AND OPERATION INSTRUCTIONS

Recloser service information
Service requirements
The SPEAR single-phase recloser has been designed with a
minimum mechanical life of 10,000 operations. The SPEAR
single-phase recloser requires minimum routine inspection
to check for physical damage and verify proper operation.
It should not be necessary to access the mechanism of the
SPEAR single-phase recloser. If entry is required, the trip
and close capacitor must be discharged prior to any contact
with the mechanism. The capacitor retains an electrical
charge, even with the control cable disconnected.
WARNING
Personal injury . The trip and close capacitor retains
an electrical charge . Always discharge the trip and
close capacitor prior to performing any service on the
mechanism . Contact with a charged capacitor can result
in skin burn or electrical shock .

Discharge trip and close capacitor
To discharge the trip and close capacitor:
1. Remove the recloser from service. Refer to the
Removing recloser from service
section of this
manual.
CAUTION
Equipment damage . Always unplug the control cable
from the control prior to discharging the capacitor .
Failure to do so can result in resistor damage .

2. Unplug the control cable from the control.
WARNING
Falling equipment . Use the lifting lugs provided and
follow all locally approved safety practices when lifting
and mounting the equipment . Lift the unit smoothly
and do not allow the unit to shift . Improper lifting
can result in severe personal injury, death, and/or
equipment damage .

IMPORTANT
When the head casting and mechanism are removed from
the tank, the center of gravity changes. Secure an additional
strap to the horizontal side arm to prevent the module from
tipping.
3. Loosen bolts that secure head casting and remove
mechanism from tank.
4. Locate the white Discharge button on the actuator
5. Push and hold in the Discharge button. The Discharge
LED will light up and gradually dim as capacitor energy
is discharged. This will take approximately 45 to 60
seconds.
6. When the light completely dims, release the button.

After approximately twenty minutes, the discharged
capacitor may have recharged up to 7 V. If this
occurs, the discharge LED will light up if the
discharge button is pushed. Press the discharge
button to discharge.
8. Reinstall the module: center it over the tank lip and
tighten the four bolts that secure the module to 25–40
ft•lbs (34 –54 Nm).
Frequency of inspection
Because these reclosers are applied under widely varying
operating and climatic conditions, service intervals are
best determined by the user based on actual operating
experience. However, solid-insulated, vacuum-interrupting
reclosers should be inspected every ten years.
The recloser control 24 VDC control battery has a life
expectancy of four years. It is recommended that the
battery be replaced after four years or if the battery fails
a battery test (after sufficient recharge time) - whichever
occurs first.
High-potential withstand tests
Each SPEAR single-phase recloser is carefully tested
and adjusted at the factory to operate according to the
published data. The recloser leaves the factory ready for
installation, but to ensure there was no damage during
