Smart System EIFE Embedded Ethernet Interface

EIFE Embedded Ethernet Interface Description

EIFE Embedded Ethernet Interface


The EIFE embedded Ethernet interface module enables drawout Masterpact MTZ circuit breakers to be connected to an Ethernet network.

It provides digital access to the data delivered by the Masterpact’s Micrologic X control unit. In addition it monitors the three positions of the circuit breaker when inserted in its cradle:

  • Circuit breaker racked IN.

  • Circuit breaker racked OUT.

  • Circuit breaker in test position.

Provides an Ethernet access to a single drawout Masterpact MTZ circuit breaker.


One circuit breaker is connected to the EIFE interface via its ULP port.

EIFE Interface Features

  • Dual 10/100 Mbps Ethernet port for simple daisy chain connection.

  • Device profile web service for discovery of the EIFE interface on the LAN.

  • Ethernet interface for drawout Masterpact circuit breakers.

  • Embedded set-up web pages.

  • Embedded monitoring web pages.

  • Embedded control web pages.

  • Cradle status management (CE, CD, CT).

  • Built-in e-mail alarm notification.

  • RBAC (Role Base Access Control).


The EIFE interface is mounted on the cradle of the drawout circuit breaker. There are two types of dedicated EIFE ULP cable, one for Masterpact MTZ1 devices and one for Masterpact MTZ2/MTZ3 devices.

24 Vdc Power Supply

The EIFE power supply is provided by the ULP port through the dedicated EIFE ULP cable.

EIFE Interface Firmware Update

The firmware can be updated using Ecoreach software.

Required Circuit Breaker Communication Accessory

The connection to the EIFE interface requires an ULP communication port on the cradle of the drawout Masterpact MTZ circuit breakers.
