System Diagnostics
Digitrip RMS 610 and 910 models of
trip units provide long delay, short
delay, instantaneous, and ground fault
cause of trip LEDs on the front of the
unit. Their display shows a magnitude
of trip information, as well as remote
signal contacts, for improved system
alarming.
System Monitoring
Digitrip 610 and 910 Trip Units
have the capability to monitor
phase currents, as well as neutral or
ground currents. This information is
displayed on a large digital display
mounted on the unit.
Digitrip RMS 910 Trip Units can
also provide the user with power
and energy monitoring capability.
Peak power demand, present power
demand, and total energy, as well as
forward and reverse energy can be
monitored with this unit.
Series G Molded Case Circuit Breakers
15 – 2500 Amperes for UL, CSA & IEC Applications
Series G Electronic Trip Units
Digitrip RMS 910 Trip Units have the
additional capability of monitoring
line-to-line voltage, as well as system
power factor. Both parameters are dis-
played in the digital display window
and are supported by LEDs to indicate
which parameter is being displayed.
Harmonics Monitoring
Digitrip RMS 910 Trip Units are capa-
ble of displaying values of current
harmonics in the digital display win-
dow. Percentage of harmonic content
can be monitored for each phase,
up to the 27th harmonic. Additionally,
a total harmonic distortion value can
be calculated and displayed.
Communications
Digitrip RMS 910 units have built-in
communications options to allow all
protection, monitoring, and control
information to be transmitted back to a
central location via the Cutler-Hammer
PowerNet

system.
Field Testing
Integral field testing capability is
provided on all 610 and 910 Trip Units.
No additional test set is needed to per-
form both trip and no trip field testing.
