Power Meter Functions
In addition to protection functions, Micrologic A/E trip units offer all the functions of Power Meter
products as well as operating assistance for the circuit breaker.
Micrologic A/E 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 Functions
Micrologic Trip Unit LCD
The user can display all the protection settings and the main measurements on the LCD screen of the
trip unit.
• Micrologic A trip unit: instantaneous rms current measurements
• Micrologic E trip unit: voltage, frequency and power measurements and energy metering, in
addition to the measurements offered by Micrologic A
To make the display available under all conditions and increase operating comfort, an external power
supply is recommended for Micrologic A trip unit. It is required to:
• display faults and interrupted current measurements
• use all the functions of Micrologic E trip unit (such as metering of low power and energy values)
• ensure operation of the communication network
The external power supply can be shared by several devices. For description, see page 109.
FDM121 Display Unit (One to One)
The FDM121 switchboard display unit can be connected to a communication (COM) option (Breaker
Communication Module [BSCM]) 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 (BSCM) unit is supplied by the same power supply via the circuit
breaker ULP cord connecting it to the FDM121. See page 72 for more information.
