IFM Interface

The IFM interface enables an intelligent modular unit (IMU) containing a circuit breaker equipped with a communicating MicroLogic trip unit to be connected to a two-wire Modbus-SL RS-485 serial line Modbus network.

Each circuit breaker has its own IFM interface and a corresponding Modbus address.

The IFM interface with part number LV434000 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.
