Universal remote power racking system (Type RPR-2)
For maximum safety during drawout breaker levering
operations, the universal remote power racking system
(RPR-2) can be employed on Magnum, as well as other
drawout low- and medium-voltage power circuit break-
ers that use rotation of a shaft for insertion or removal.
Remote control is accomplished by an operator pendant
with an INSERT and REMOVE pushbutton station and a
25-foot connecting cable. The RPR-2 requires 120 Vac, 15
A power from a common plug receptacle. Status indication
and selectable torque limitation matched to the breaker
racking mechanism are also provided. More info can be
found at eaton.com/eess.
Lifting yoke and floor lifting device
Magnum breakers include lifting ears on each side to
accept a lifting yoke (or suitable sling) to facilitate lifting
using a skyhook from a top of gear lifter, floor lifter or
crane. Various lifting yoke style numbers are available for
all Magnum frame types in both three-pole and four-pole
configurations.
A roll-on-the-floor lifting device is equipped with a skyhook
for use in conjunction with a breaker lifting yoke or suitable
sling to lift the breaker from above. Shelf-type roll-on-
the-floor lifters can also be used to lift the breaker from
underneath without a lifting yoke.
Test cabinet
The test cabinet is a separately mounted device with
open and close pushbuttons that facilitate bench testing
of electrically operated Magnum breakers. An input power
cord is provided for connection to a 120 Vac, 15A plug
receptacle. The test cabinet output power is matched to
the breaker control voltage(s) and is connected to the
breaker via a cord that plugs into the breaker secondary
contacts.
Auxiliary power module
Providing auxiliary control power to the PXR trip unit will
provide full functionality even when the circuit breaker
is open or when the circuit breaker is under very light
load such that the self-powering current transformer
cannot provide energy to power the trip unit. The relays
and communication channels require auxiliary control
power for operation. Auxiliary control power is connected
to the circuit breaker’s secondary terminal block. We
recommend an isolated supply such as the Eaton PSG
family, 24 Vdc. 0.5A.
Remember: auxiliary control power is not required to
provide current protection features. Protection is active
well before any overload. The trip unit begins to power-up
at very low levels of current (approximately 40A).
