FDM121 Front Display Module for One Circuit Breaker

The FDM121 display shows the measurements, alarms, and operating assistance data from the Intelligent Modular Unit (IMU). The FDM121 display can control a circuit breaker that is equipped with a motor mechanism or with the pre-defined application performed by the IO module.

The FDM121 display with part number TRV00121 or STRV00121 is compatible with the following ranges of circuit breaker:

MasterPacT MTZ circuit breakers
MasterPacT NT/NW circuit breakers
ComPacT NS circuit breakers
PowerPacT P- and R-frame circuit breakers
ComPacT NSX circuit breakers
PowerPacT H-, J-, and L-Frame circuit breakers

NOTE:

The information related to the new generation of ComPacT NS and PowerPacT P- and R-frame circuit breakers in this document applies to the existing range ComPact NS and PowerPact P- and R-frame circuit breakers also. The exceptions are mentioned wherever applicable.
The information related to the new generation of ComPacT NSX and PowerPacT H-, J-, and L-Frame circuit breakers in this document applies to the existing range ComPact NSX and PowerPact H-, J-, and L-frame circuit breakers also. The exceptions are mentioned wherever applicable.
These new ranges are based on the same technical and dimensional architecture as that of the existing range of circuit breakers.
