Systems' warranty shall run only to the first Buyer of a product from Hubbell Power Systems, from Hubbell Power Systems' distributor, or from an original equipment manufacturer reselling the Hubbell
Power Systems' product, and is non-assignable and non-transferable and shall be of no force and effect if asserted by any person other than such first Buyer. This warranty applies only to the use of the
product as intended by Seller and does not cover any misapplication or misuse of said product.
Warranty - Application
Hubbell Power Systems, Inc. does not warrant the accuracy of and results from product or system performance recommendations resulting from any engineering analysis or study. This applies regardless
of whether a charge is made for the recommendation, or if it is provided free of charge.
Responsibility for selection of the proper product or application rests solely with the purchaser. In the event of errors or inaccuracies determined to be caused by Hubbell, its liability will be limited to the

Single-Phase Recloser
Description
The Versa-Tech
®
Recloser is a unique and patented design.
The interrupter, drive mechanism, control, and housing
are raised to the system potential. The entire assembly is
then insulated from ground using a standard polymer post
insulator. This compact simplified design eliminates the
potential for an insulation breakdown failure.
Magnetic/vacuum-interruption technology
Fault interruption occurs in the reclosers vacuum
interrupter. The vacuum interrupters state-of-the-art
contacts utilize axial magnetic fields to interrupt in diffuse
mode for maximum interrupter life. The vacuum interrupter
is supported by an insulating support housing with bonded
silicone rubber over-molding for maximum weather
resistance.
The drive for the vacuum interrupter is provided by a
mechanism with a magnetic actuator. The actuators rare-
earth neodymium magnet provides the latching and holding
force for the vacuum interrupter in the closed position. A
spring provides the pressure to hold the vacuum interrupter
in the open position. Together, the rare-earth magnet and
the spring arrangement allow the mechanism to be stable
in the open or closed position without the need for external
power. To open the vacuum interrupter, a coil on the magnetic
actuator is pulsed in one direction. To close, the same coil is
pulsed in the other direction. Energy to open and close the
recloser is provided by a set of capacitors.
Microprocessor electronic control
The control for the recloser is provided by a microprocessor-
based electronic circuit. The controls design allows complete
flexibility and user choice of minimum trip, time-current
curves and sequencing parameters. User access to all
parameters is provided through an RS-232 serial connection.
Current sensing for the control occurs through a 1000:1
current transformer.
Self-powered operation
No external transformer power for the recloser is required.
Power for the control and the mechanism is converted from
fault or load current using two power current transformers.
The open and close capacitors that drive the recloser are
charged by the load or fault current through the power
current transformers. Using this approach the recloser will
continue to open and close as necessary without the need
for external power or even the hot-stick replaceable lithium
battery pack. The low self-discharge lithium batteries are
required only for closing the recloser after lockout or manual
open.

Automatic operation
In the closed position, the Versa-Tech
®
Recloser, operates
automatically per the user-programmed settings.
Manual operating Handle
The Manual Operating Handle allows manual operation of
the recloser with a hotstick.
Non-reclosing lever
The Non-Reclosing Lever is shown above in its normal (or up)
position. When this handle is rotated to the down position,
the recloser will trip using TCC1 and lockout on any current
above the minimum trip. The Non-Reclosing lever does not
interfere with the Manual Operating Handle.
Lockout beacon
The Lockout Beacon is a unique feature to aid the utility
lineman in identifying a locked out recloser. This high-
brightness, sunlight-visible amber LED will flash once
every 3 seconds when the recloser has sequenced to lockout.
The beacon will continue to flash every 3 seconds until the
lineman closes the recloser or 4 hours have passed. After
4 hours, the flashing beacon will automatically shut off.
Powered by the reclosers lithium batteries, the beacons duty
cycle was set to have a negligible effect on battery life.
Operations counter
The Operations Counter is an electromechanical counter
which records the number of open operations, both manual
and automatic, initiated by the control.

8-Year battery replacement
Battery power is used for these func-
tions only: To close the recloser after
installation or lockout, the radio if load
current is less than 5 amps, and the
flashing lockout beacon. The batteries
are made of a very stable lithium chem-
istry, which is designed with a low self
discharge that they can function cor-
rectly for up to 10 years. Hubbell Power
Systems recommends that users replace
the batteries on an 8 year cycle.
The battery bayonet was designed to
be replaced using a hot stick while
the recloser is in service. The battery
bayonet utilizes a twist lock design. It
is easily removed by pushing in slightly
and turning.
