Advanced Features and Communications
Basic Metering is standard. The metering option
displays current for all three phases.
Advanced Metering is optional. This feature displays
current , voltage, real power, reactive power, apparent
power, peak power demand, energy, frequency, and
power factor for all three phases. Proper operation
of the advanced metering function requires multiple
system accessories including power supplies, voltage
conditioners, junction boxes, and interconnect cables.
Modbus Communications is optional. The
communications option allows the breaker/trip unit to
communicate all breaker data to an outside network.
Waveform Capture is optional. This option stores eight
cycles worth of data into digital memory that can be
output via the trip unit’s DB-15 connector, or over the
Modbus interface.
Two Programmable Output Contacts (two) are optional.
This feature is included on breakers/trip units that are
optioned with any of the following functions or features
• Ground Fault Alarm
• Zone Selective Interlock
• Reduced Energy Let-Through
• Protective Relays
Breakers/trip units optioned with any of the above
features have a 20-pin harness/connector and require
accessories that accommodate the 20-pin connector
(see section on equipment interfaces).
Rating Plugs
The microEntelliGuard TM Trip Unit uses a rating plug to
establish or change the current rating of the breaker.
Each breaker frame/sensor combination has multiple
rating plugs available that are interchangeable
within the trip unit . Rating plugs available for
microEntelliGuard TM Trip Units are shown in Table 2.
These rating plugs are compatible with EntelliGuard trip
units. Note that the same rating plug catalog number
can be used across multiple breaker sensor ratings.
For example, GTP0150U0104 is a 150 amp-rating plug
that can be used in the Spectra microEntelliGuard TM G
frame with 150 amp or 400 amp sensors.
