Power Meter Functions
In addition to protection functions, MicroLogic A/P/H trip units offer all the functions of Power Meter products as well as operating assistance for the circuit breaker.
MicroLogic A/P/H trip unit measurement functions are made possible by the MicroLogic trip unit’s intelligence and the accuracy of the sensors. They are handled by a microprocessor that operates independent of protection functions.
Display Function
FDM121 Display Unit (One to One)
The FDM121 switchboard display unit can be connected to a communication (COM) option (Breaker Communication Module [BCM ULP]) using a circuit breaker ULP cord to display all measurements on a screen. The LCD screen is 3.78 x 3.78 in. (96 x 96 mm). The FMD121 display unit requires a 24 Vdc power supply. The COM option (BCM ULP) unit is supplied by the same power supply via the circuit breaker ULP cord connecting it to the FDM121. See FDM121 Display for more information.

For all FDM, in addition to the information displayed on the MicroLogic trip unit LCD, the FDM screen shows demand, power quality, and maximum/minimum ammeter values along with histories and maintenance indicators.
Measurement Function
Instantaneous RMS Measurements
The MicroLogic trip unit continuously displays the RMS value of the highest current of the three phases and neutral (Imax). The navigation buttons can be used to scroll through the main measurements.
In the event of a fault trip, the trip cause is displayed.
The MicroLogic A trip unit measures phase, neutral, and ground fault currents.
MicroLogic P/H trip units offer voltage, power, power factor, frequency, and cos φ in addition to the measurements provided by MicroLogic A trip units.
Maximum/Minimum Ammeter
Every instantaneous measurement provided by MicroLogic A trip units can be associated with a maximum/minimum ammeter. The maximum for the highest current of the three phases, neutral, and demand current can be reset using the FDM display unit or the communication system.
Energy Metering
The MicroLogic P/H trip units also measures the energy consumed since the last reset of the meter. The active energy meter can be reset using the MicroLogic trip unit keypad, the FDM display unit, or the communication system.
Demand and Maximum Demand Values
MicroLogic P/H trip units also calculate demand current and power values. These calculations can be made using a block or sliding interval that can be set from five to sixty minutes in steps of one minute. The window can be synchronised with a signal sent through the communication system. Whatever the calculation method, the calculated values can be recovered on a PC through the communication network.
Ordinary spreadsheet software can be used to provide trend curves and forecasts based on this data. They provide a basis for load shedding and reconnection operations used to adjust consumption to the subscribed power.
Power Quality
The MicroLogic H trip unit calculates power quality indicators taking into account the presence of harmonics up to the fifteenth harmonic, including the total harmonic distortion (THD) of current and voltage.

Histories
Maintenance Indicators
MicroLogic trip units have indicators for, among other items, the number of operating cycles, load profile, and operating times (operating hours counter).
It is possible to assign an alarm to the operating cycle counter to plan maintenance.
The various indicators can be used together with the trip histories to analyze the level of stresses the device has been subjected to.
Contact Wear
Contact wear algorithms only function on MasterPacT circuit breakers, and contact wear cannot be selected for PowerPacT or ComPacT circuit breakers.
Each time a MasterPacT circuit breaker opens, the MicroLogic P/H trip unit measures the interrupted current and increments the contact-wear indicator as a function of the interrupted current, according to test results stored in memory. Breaking under normal load conditions results in a very slight increment. The indicator value may be read on the FDM display.
It provides an estimation of contact wear calculated on the basis of the cumulative forces affecting the circuit breaker. When the indicator reaches 100%, it is advised to visually inspect the contacts per the instructions in the circuit breaker user guide.
Circuit Breaker Load Profile
MicroLogic A/P/H trip units calculate the load profile of the circuit breaker protecting a load circuit. The profile indicates the percentage of the total operating time at four current levels (% of circuit breaker In):
-
0 to 49% In
-
50 to 79% In
-
80 to 89% In
-
≥ 90% In.
This information can be used to optimize use of the protected equipment or to plan ahead for maintenance interval extensions.
Management of Installed Devices
Each circuit breaker equipped with a COM option (BCM ULP) can be identified using the communication system:
-
serial number
-
firmware version
-
hardware version
-
device name assigned by the user.
This information together with the previously described indications provides a clear description of the installed devices.

FDM121 Display
MicroLogic trip unit measurement capabilities come into full play with the FDM121 display. It connects to the COM option (BCM ULP) with a circuit breaker ULP cord and displays the MicroLogic trip unit information. The result is a true integrated unit combining a circuit breaker and a power meter. Additional operating assistance functions can also be displayed.
An FDM121 display unit can be connected to ULP communication devices using a prefabricated cord to display all measurements, alarms, histories and event tables, maintenance indicators, and management of installed devices on a screen.
The FMD121 display unit requires a 24 Vdc power supply.
The FDM121 is a display that can be integrated with the PowerPacT H/J/L/P/R or MasterPacT NW/NT circuit breaker systems. It uses the sensors and processing capacity of the MicroLogic trip unit. It is easy to use and requires no special software or settings. It is immediately operational when connected to the circuit breaker by a ULP cord.
It also provides monitoring and control with the use of the I/O application module, the motor mechanism module, or the circuit breaker communication module (BCM ULP).
The FDM121 has a large display, but requires very little depth. The anti-glare graphic screen is backlit for easy reading even under poor ambient lighting and at sharp angles.
FDM121 Display of MicroLogic Trip Unit Measurements and Alarms
The FDM121 is intended to display MicroLogic trip unit measurements, alarms and operating information. It cannot be used to modify the protection settings.
Measurements can be easily accessed using a menu. All user-defined alarms are automatically displayed. The display mode depends on the priority level selected during alarm set-up:
-
high priority: a pop-up window displays the time-stamped description of the alarm and the orange Alarm LED flashes;
-
medium priority: the orange Alarm LED goes continuously on;
-
low priority: no display on the screen.
All faults resulting in a trip automatically produce a high-priority alarm, without any special settings required. In all cases, the alarm history is updated. The MicroLogic trip unit saves the information in its non-volatile memory in the event of an FDM121 power loss.
FDM121 Status Indications and Remote Control
When the circuit breaker is equipped with the Breaker Communications Module (BCM ULP), the FDM121 display can also be used to view circuit breaker status conditions:
-
O/F: ON/OFF
-
SD: trip indication
-
SDE: fault-trip indication (overload, short-circuit, or ground fault).
When the circuit breaker system is equipped with the I/O application module, the FDM121 can monitor and control:
-
cradle management
-
circuit breaker operation
-
light and load control
-
custom applications.
When the circuit breaker is equipped with the COM option (BCM ULP) (including connection to shunt close [XF] and shunt trip [MX1] communication voltage releases), the FDM121 display can also be used to control (open/close) the circuit breaker.
Two operating mode are available:
-
local mode: open/close commands are enabled from the FDM121 while disabled from the communication network;
-
remote mode: open/close commands are disabled from the FDM121 while enabled from the communication network.
FDM121 Main Characteristics

-
A 24 Vdc type auxiliary power supply must be connected to a single point on the ULP system. The FDM121 display has a two-point screw connector on the rear panel of the module for this purpose. The ULP module to which the auxiliary power supply is connected distributes the supply via the ULP cable to all the ULP modules connected to the system and therefore also to MicroLogic trip unit. See wiring diagram later in this section.
-
Two RJ45 jacks.
The MicroLogic trip unit connects to the internal communication terminal block on the PowerPacT or ComPacT circuit breaker with the circuit breaker ULP cord. Connection to one of the RJ45 connectors on the FDM121 automatically establishes communication between the MicroLogic trip unit and the FDM121 and supplies power to the MicroLogic trip unit measurement functions.
When the second connector is not used, it must be fitted with a line terminator.
