This EIFE is an embedded Ethernet interface module designed for MasterPact MTZ drawout circuit breakers. It provides a single Ethernet access and gets all data delivered by Masterpact MTZ control unit. It monitors the three positions of the circuit breaker when inserted in its chassis (IN, OUT, TEST). The data flow is 10/100 Mbps for a simple daisy chain connection. The connection to EIFE interface requires a ULP communication port installed on the chassis of MasterPact MTZ. The EIFE is mounted on MasterPact MTZ chassis DIN rail, and is connected to the ULP port by an ULP cable (not supplied). The EIFE power supply is provided by the ULP port through the ULP cable. There are two RJ45 sockets for the connection to Ethernet network. The EIFE is entirely part of the EcoStruxure Power architecture and Ethernet ready smart panels. The EIFE firmware can be updated using EcoStruxure Power Commission software.
