The Type VXE recloser can be equipped with a variety of
factory-installed accessories to meet specific application
requirements.
Extra-Creepage Bushings
When VXE reclosers are to be installed where extensive
salt spray, smog, smoke, or other atmospheric contami-
nants reduce the effectiveness of porcelain insulation,
Extra-Creepage Bushings can be supplied. Standard
Type VXE15 recloser bushings provide 295 mm (11-5⁄8
in.) of creepage; extra-creepage accessory bushings pro-
vide 432 mm (17 in.). Type VXE27 recloser bushings pro-
vide 432 mm (17 in.) of creepage; extra-creepage acces-
sory bushings provide 673 mm (26-1⁄2 in.).
Bushing-Type Multi-Ratio
Current Transformer
A 450:5 multi-ratio current transformer for load metering
can be factory installed externally on the source- or load-
side bushing. This transformer has only one primary turn:
the bushing rod. Taps on the secondary winding provide
the different ratios. The available ratios and their corre-
sponding terminal connections (labeled A, B, C, and D)
are shown in Table 7. The terminal arrangement for the
tapped secondary is accessible when the cover plate on
the transformer housing is removed.
Low-Voltage Closing
The VXE recloser can employ 120 Vac or 240 Vac low-
voltage closing. The low-voltage ac closing accessory
provides a bridge rectifier, surge varistors, and the factory-
installed wiring to accommodate the low-voltage closing
power. Customer low-voltage power is connected at the
2-pin connector (polarity independent) in the recloser
head. This accessory requires a low-voltage closing coil.
Cable-Locking Sleeve
To prevent detachment of the control cable from the VXE
control cabinet by unauthorized personnel, a cable-locking
sleeve is available to enclose the cable plug. The plug is
passed through the sleeve and the sleeve is then fas-
tened from inside the control cabinet. There is no access
to the cable receptacle without opening the locked cabi-
net door and detaching the sleeve.
SCADA Input/Output Board
An optional factory-installed SCADA input/output circuit
board is available for the VXE control to provide remote
operation capabilities. The SCADA I/O board also includes
dry contacts to provide remote status information.
All remote features are accessed through a 19-pin recep-
tacle (Type MS 22-14 female) mounted on the bottom of
the control cabinet.
Remote Lockout
Remote lockout provides the ability to trip and lock out
the recloser from a remote signal. Operation requires a
momentary contact closure of 0.1 second between pins
D and B.
Remote Close With Cold-Load Pickup
The remote close with cold-load pickup feature provides
the control with the capability of being remotely closed
from lockout by momentary contact closure (0.1 second)
between pins E and B.
Cold-load pickup is active for a programmable time, during
which the control will be in the one-operation-to-lockout
mode and overcurrent timing will be on TCC2. If no over-
current is present during this interval, the control will
reset to the programmed operating sequence.
Remote Non-Reclose
Remote non-reclose provides the ability to remotely
place the control in the non-reclose mode by momentary
contact closure (0.1 second) between pins F and B.
Recloser Open/Close Status Indicator
The recloser status indicator provides a dry contact
(SPDT rated 1 A at 28 Vdc) to indicate open or closed
status of the recloser contacts. Contact closure occurs
between pins H and K when the recloser is closed.
Remote Lockout Status
The remote lockout status feature provides an open con-
tact between pins L and K when the control is not locked
out and a closed contact between pins M and K when the
control is locked out. Contacts are rated 1 A at 30 Vdc.
Remote Non-Reclose Status
The remote non-reclose status indicator provides a
closed contact (rated 1 A at 28 Vdc) to indicate when the
recloser is in the normal reclosing mode. Contact closure
occurs between pins J and K when the recloser is in the
reclose mode.
Remote Analog Current Monitor
The remote analog current monitor provides a 0 to 0.5
mA dc signal corresponding to 0 to 500 A of line current,
between pins C (+) and B (-). The factory calibration point
is set at 35 A with a 2.5 kΩ resistor across the output with
accuracy of ±10% from 15 to 400 A.
