Intelligent Modular Unit
Definition
A modular unit is a mechanical and electrical assembly containing one or more products to perform a function in a switchboard (incoming protection, motor command, and control).
The circuit breaker with its internal communicating components ( MicroLogic control unit or MicroLogic trip unit) and external ULP modules (IO module) connected to one communication interface is called an intelligent modular unit (IMU).
An IMU is composed around a circuit breaker from the following ranges:
-
MasterPact MTZ circuit breakers
-
MasterPact NT/NW circuit breakers
-
ComPacT NS1600b-3200 circuit breakers
-
ComPacT NS630b-1600 circuit breakers
-
PowerPacT P- and R- frame circuit breakers
-
PowerPacT H-,J-, and L- frame circuit breakers
-
The information related to the new generation of ComPacT NSX and PowerPacT H-, J-, and L- frame circuit breakers in this guide applies to the existing range ComPact NSX and PowerPact H-, J-, and L- frame circuit breakers also.
The information related to the new generation of ComPacT NS and PowerPacT P-, and R-frame circuit breakers in this guide applies to the existing range ComPact NS and PowerPact P- and R-frame circuit breakers also.
The exceptions are mentioned wherever applicable. The new ranges are based on the same technical and dimensional architecture as that of the exiting range of circuit breakers.
-
ComPacT NS and PowerPacT P- and R-frame circuit breakers are supported by IFE interface with firmware version 004 and later.
ULP Modules Per Circuit Breaker Range
The following table lists the compatible ULP modules for each range of circuit breakers.
For more information on the ULP System and its components, refer to the ULP System User Guides.

Remote Controller
A remote controller is a device that is able to communicate with an IMU using a communication interface, such as the IFE Ethernet interface. For example, FDM128 Ethernet display for eight devices, supervisor, PLC, BMS, SCADA system, and so on, are remote controllers.
For the description of Modbus registers and commands, refer to the Modbus Communication Guides.
