Accessories for Drawout Breakers

(cont.)

Padlocking Provisions

All WavePro breakers are furnished with
standard padlocking provisions for opera-
tor safety. The breaker may be placed in a
“trip-free” position by utilizing the padlock
provision on the breaker escutcheon which
holds the OPEN button depressed. This
padlocking feature holds up to three locks.

The breaker may also be padlocked in the
TEST or DISCONNECT position. When in
either of these positions, the breaker lines
up with padlocking provisions in the com-
partment or on the drawout rails and will
accept up to three padlocks to secure the breaker in either
the TEST or DISCONNECT position.

“PM-Ready”

In its most basic form, a manually operated WavePro break-
er, with a Power+™ or MicroVersaTrip Plus™ trip unit and
no other accessories, may be able to be supplied without
secondary disconnect points. The “PM-Ready” option equips
the breaker with a secondary disconnect and inputs for
24Vdc auxiliary power, communications and 3-phase voltage
signals. If the breaker is already equipped with any combina-
tion of ground fault protection, zone selective interlocking,
shunt trip, auxiliary switch, bell alarm, undervoltage device,
electric lockout, or is electrically operated, the PM-ready
wiring is automatically included and does not have to be
specified. This “PM-Ready” option makes upgrading a
WavePro breaker to MicroVersaTrip PM as simple as chang-
ing the trip unit. Breaker cubicles can be equipped with the
necessary wiring to further simplify a PM-upgrade.

Racking Tool

(Equipment accessory)

The racking tool is a special drive wrench with a square

⁄

socket that engages the racking mechanism on the breaker.
One racking tool is used for all WavePro™ circuit breakers.
0324B4721G001 Without universal joint – all applications

except as noted below (standard)

0324B4724G001 With universal joint – must use for outdoor

applications when there is a large frame
(3200 – 5000A) breaker or fuse rollout
on the extreme right end of the line-up.
Can be used on all other breaker
applications, also.

Remote Charge Indicator Switch

(Field installable kit available)

The remote charge indicator switch is a normally open dry
contact that closes when the closing springs of the breaker
are fully charged. This option is available on manually and
electrically operated breakers. The contact is rated 4.0 amps
at 120Vac and 0.5 amps at 125Vdc.

Remote Close Accessory with One-Shot
Electronic Close Circuit

(Field installable

kit available)

The remote close accessory is an electrically
operated solenoid, which when energized,
closes the breaker. It is suitable for control interlock schemes
in which manual closing capability would not be convenient
or would be too slow. It is an optional accessory for a manual-
ly operated breaker but is always supplied with electrically
operated breakers. The remote close accessory consists of the
“one-shot” electronic close circuit, with built-in anti-pump
feature, and the closing solenoid. The remote close accessory
is continuously rated and operates as follows.

Applying control voltage to the close circuit produces a
250msec pulse to the closing coil which in turn releases the
energy stored in the closing springs. The anti-pump feature
prevents the breaker from repeatedly closing if the close sig-
nal is maintained. A momentary close signal (

1⁄

second dura-

tion) is sufficient to close the breaker but if the close signal is
maintained while the breaker is closed, the signal must be
removed and then reapplied in order to reclose the breaker.
Reset time for the anti-pump circuit is approximately 2.5 sec-
onds. For applications requiring rapid reclosure of a circuit
breaker, a momentary close signal should be used. This
allows the anti-pump circuit to reset while the closing springs
are recharging and the breaker is then ready to reclose with-
out any additional time delays. A close signal applied to a
closed breaker will provide a pulse to the close coil but the
closing mechanism is mechanically blocked thereby prevent-
ing the closing springs from discharging. The close signal
must be removed as stated above before the breaker can be
reclosed. Control power requirements for electrically charg-
ing and closing the breaker are shown in Tables 9.2 and 10.1.
