Operations Counter –
Field installable kit available (Breaker accessory)
The operations counter mounts on the breaker as a five-
digit, non-resettable counter actuated by the breaker
closing mechanism.

"PM-Ready" – (Breaker accessory)
In its most basic form, a manually operated WavePro breaker,
™
with a Power+ or MicroVersaTrip Plus
other accessories, may be able to be supplied without sec-
ondary 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 combination of
ground fault protection, zone selective interlocking, shunt
trip, auxiliary switch, bell alarm, undervoltage device, electric
lockout, MicroVersaTrip PM
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 changing
the trip unit.
Position Switch – By-pass switch or TOC truck-operated-
contact (Equipment accessory)
This accessory is available with either two NO and two NC or
six NO and six NC electrically separate contacts. The switch
changes state when the breaker is racked from the CONNECT
to the TEST position. The position switch is used to indicate
the drawout position of the breaker, enable/disable control
circuits, and/or bypass auxiliary contacts when the breaker
is in the TEST/DISCONNECT/WITHDRAWN positions.

Racking Tool – (Equipment accessory)
The racking tool is a special drive wrench with a square 1⁄2"
socket that engages the racking mechanism on the breaker.

Remote Charge Indicator Switch –
Field installable kit available (Breaker accessory)
The remote charge indicator switch is a normally open or
normally closed dry contact that changes state when the
closing springs of the breaker are fully charged. This option is
available on manually or 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 (Breaker accessory)
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 manually 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 signal
is maintained. A momentary close signal (1/2 second duration)
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
seconds. 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 without
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 preventing 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 charging and
closing the breaker are shown in Tables 15.3 and 16.1.
