Instructions for installation,

VCP-W vacuum circuit breakers
EATON

Outdoor storage of the breaker element is NOT recommended.
If unavoidable, the outdoor location must be well drained and a
temporary shelter from sun, rain, snow, corrosive fumes, dirt, falling
objects, and excessive moisture must be provided. Containers
should be arranged to permit free circulation of air on all sides
and temporary heaters should be used to minimize condensation.
Moisture can cause rusting of metal parts and deterioration of high
voltage insulation. A heat level of approximately 400 watts for each
100 cubic feet (2.83 cubic meters) of volume is recommended with
the heaters distributed uniformly throughout the structure near the
floor.
Indoor storage should be in a building with sufficient heat and air
circulation to prevent condensation. If the building is not heated, the
same general rule for heat as for outdoor storage should be applied.
3.5 Tools and accessories
Tools and accessories, both standard and optional, are available for
use with the circuit breaker element (Figure 3). If not specified
accessories can be used for 36 in. wide and 26 in. wide breakers.
Spin-free levering-in crank:
Used to crank breaker between
DISCONNECT, TEST, and CONNECTED positions.
Extension rails:
Permits breaker to be withdrawn from its compart-
ment.
Rail clamps:
Used to secure breaker to extension rails.
Lifting yoke:
Used to lift breaker.
Manual charging handle:
Used to charge closing springs manually.
Portable lifter:
Used to lift breaker to or from extended rails.
Breaker lift pan:
This accessory enables the breaker to be lifted
from the ground to any height cell without the extension rails. It
consists of a portable lifter and a MV breaker lift pan.
•
Portable lifter;
•
MV breaker lift pan with short extension rail kit for 36”or 26” wide
breaker.
Drawout ramp:
Used to insert or withdraw breaker from lower
compartment without portable lifter.
Docking transport dolly:
Used to insert or withdraw breaker from
lower compartment without portable lifter or move breaker from one
location to another.
Electrical levering-in device:
BPI pan assembly:
Integral Motorized Racking (MR2) used to electrically move
breaker between DISCONNECT/TEST, or DISCONNECT, TEST, and
CONNECTED positions is available. Specified by description as
opposed to a style number.
If the external electric levering-in device which mounts to the door or
pan assembly is used, then the breaker can be moved between the
DISCONNECT and CONNECTED positions.
The process of levering the breaker from the DISCONNECT to the
TEST position would need to be performed manually (approximately
6 turns).
Non-BPI pan assembly:
Used to electrically move the breaker between DISCONNECT/TEST
and CONNECTED positions.
Truck operated cell (TOC) switch:
Indicates when breaker is in the
CONNECT position. Furnished with standard push on wire termi-
nals. Optional ring tongue terminals are available.
Mechanism operated cell (MOC) switch:
Provides additional
normally open and closed contacts for when control and protection
scheme exceeds the available auxiliary contacts in the breaker.
Furnished with standard push on wire terminals. Optional ring
tongue terminals are available.
This feature is available in two different configurations:
1.) Functions in both the TEST and CONNECT positions, or
2.) Functions only in the CONNECT position.
Eaton strongly recommends use of the TEST and CONNECT position
configuration.
Test jumper:
Used to operate breaker electrically while breaker is on
extension rails or transport dolly.
Test cabinet:
Used to provide power to operate breaker outside its
compartment for the purpose of testing functionality.
Key provisions with positional interlock:
This enables locking of
the levering-in cage when the breaker is in the TEST position with a
padlock or keyed cylinder lock.
Wheel conversion kit (MG & TD only):
Due to how the manual
ground and test device is designed this is the best direct roll-in
wheel kit to use.
Wheel conversion kit for direct roll-in:
This wheel kit can be used
to convert a standard breaker or electrical ground and test device to
a direct roll-in version.
Conversion kit ROF to non-ROF:
This kit is used to convert a direct
roll-in cell to a non direct roll-in cell. It provides the teeter totter
feature that prevents removing a breaker from the breaker cell when
the extension rails or MV breaker lift pan are not in place. Also,
the short ramp feature in the front of each rail would need to be
removed.
Conversion kit non-ROF to ROF:
This kit is used to convert a non-
direct roll-in cell to a direct roll-in cell. It provides the ramp feature
that goes on the end of each rail to help guide the steel wheels on
the side of the breaker up onto the rail rolling surface. This is only
to be used in the lower switchgear cells that are level with the floor.
The teeter totter feature that keeps the breaker from being rolled out
of the cell would need to be removed.
Secondary conversion kit:
This kit converts an automatic secondary
in a BPI pan assembly to a manual enabled automatic secondary.
When the release lever is raised above the stop feature the second-
aries will slide forward to automatically connect, see section 8.2 for
more details.
Closed door racking guide:
This feature can be added to the front
of the BPI pan assembly to provide a guide for the manual levering-
in tool when the switchgear door is closed to guide the levering-in
crank socket onto the levering-in drive screw nut.
