GE WavePro LVPCB Application Manual page 3

WavePro circuit breakers are the newest generation of GE
low voltage power circuit breakers. WavePro builds on the
experience of the AKR breaker line to bring new conve-
nience and safety features while retaining the robustness of
GE's long-standing power circuit breaker products. WavePro
breakers are ANSI designed and carry the UL label. They
are designed to withstand short circuit stresses equal to their
short time interrupting ratings. This means that maximum
selectivity with downstream devices can be attained because
instantaneous trips are not required to achieve the breaker's
short circuit rating. This attests to the ruggedness of the
WavePro design and places it ahead of insulated case
breakers and other maker's power circuit breakers in many
critical applications. WavePro breakers can be applied on
power systems from 208 to 600 volts and have current ratings
of 800 through 5000 amperes. Short circuit interrupting
ratings for WavePro breakers range from 30kA to 200kA
rms symmetrical.
Why Specify Low Voltage Power Circuit Breakers?
All circuit breakers perform the function of basic circuit
protection. What separates low voltage power circuit break-
ers (LVPCB) from insulated case (ICCB) and molded case
(MCCB) circuit breakers are features and ratings that make
the equipment application safer to operate, easier to main-
tain, and maximize equipment uptime. Some of the key dif-
ferences are:
LVPCB
Maximum ambient 40°C equipment ambient
operating temperature (55°C breaker ambient)
Nominal/Maximum 240/254v
operating voltage 480/508v
600/635v
Short circuit testing 30 cycles @ 15% PF
(Instantaneous trips not required
for interrupting rating)
Switchgear/Switchboard Drawout (closed door)

Greater Convenience And Operational Safety
General Electric pioneered the closed door drawout design
for low voltage power circuit breakers with the AK line of
breakers. WavePro retains that safety feature and adds more
features. Control, status and circuit information are all
available on the front of the breaker with the breaker
compartment door closed. All breakers have a flush-mounted
handle for charging the closing springs. Operation of the
breaker can be accomplished through manual OPEN/
CLOSE buttons on the escutcheon. The escutcheon also
includes indicators for closing spring status, main contact
status, and breaker drawout position. Trip units are mounted
behind a sealable cover for easy viewing of the display and
access to the rating plug test receptacle. When equipped
with a bell alarm, the target/reset button is also mounted in
the escutcheon. The charging handle and the close and open
push buttons are double insulated from live components to
provide additional operator safety. A standard padlock device
allows you to install up to three padlocks to prevent acciden-
tal or unauthorized closing of the breaker.
Field Installable Accessories
WavePro breakers feature standardized wiring to dedicated
secondary disconnect points for all accessories. This allows
you to easily add accessories to the breaker should it
become necessary after the breaker is installed. Field
installable accessories include auxiliary switch, shunt trip,
undervoltage device, electrical lockout device, bell alarm
with or without lockout, "hidden-on" button, close and trip
push button covers, remote close accessory, remote charge
indicator and operations counter. Trip units can be upgraded
easily and the breakers can be made "power management
ready" so that stepping up to the top-of-the-line MicroVersaTrip
PM trip unit is as easy as replacing the trip unit — no
additional modifications to the breaker are required.
Three Choices Of Advanced, Solid-State Trip Units
For basic functionality, the Power+™ trip unit gives you
straightforward means of providing overload and short
circuit protection on a WavePro circuit breaker. Tripping
characteristics are easily adjusted by simple-to-use rotary
switches. The trip unit is upgradeable to ground fault by
simply inserting a ground fault rating plug. An optional
target module allows for target monitoring and also functions
as a trip unit health indicator. Enhanced MicroVersaTrip
ICCB/MCCB
Plus™ and MicroVersaTrip PM™ trip units give you two ways
25°C equipment ambient
(40°C breaker ambient) to monitor and control the WavePro breaker with unprece-
240/240v
dented ease. A simple keypad lets you program and display a
480/480v
variety of functions including tripping characteristics, remote
600/600v
communications, status information and protective relaying,
3 cycles @ 20% PF
and allows integration with GE POWER LEADER™ Power
Management Systems. The trip unit display also allows view-
Drawout (not closed door) ing of many standard metering parameters as well as pickup
or Stationary
alarms, trip target indications and fault status information.
