Introduction

Overview

The IFM Modbus-SL interface for one circuit breaker enables an intelligent modular unit (IMU) with a ComPact, PowerPact or MasterPact circuit breaker, 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.

Types of IFM Interface

The part number of the IFM interface is LV434000. The IFM interface part number LV434000 completely replaces the IFM interface with part number TRV00210 or STRV00210.

NOTE:
  • The IFM interface data for the IFM interface with part number LV434000 is the same as for the IFM interface with part number TRV00210 or STRV00210.

  • The IFM interfaces with part number TRV00210 or STRV00210 are not compatible with MasterPact MTZ circuit breakers.

IFM Interface Features

The main features of IFM interface are:

  • Single Modbus serial line interface provided in

    • RJ45 connector interface

    • Stacking connection interface

  • HMI rotary dials for address settings and padlock option

  • Pushbutton for test functionality
