Schneider Electric LV851100SP MasterPact MTZ1 EIFE Ethernet Interface Drawout Air Circuit Breaker Accessory

The Schneider Electric LV851100SP is an EIFE embedded Ethernet interface module for drawout MasterPact MTZ1 circuit breakers, giving the breaker's control unit a single 10/100 Mbps Ethernet TCP/IP-to-Modbus gateway. It also monitors the breaker's connected, test, and disconnected chassis positions. It weighs 0.075 kg and is rated IP30 for an ambient range of -20 to 70 degrees C.

Selection Notes

The LV851100SP is sized for the MTZ1 frame only; the MTZ2/MTZ3 equivalent is the LV851200SP. It requires a ULP communication port already installed on the chassis — fit the LV850064SP ULP port module first on a drawout MTZ1 breaker — since the EIFE itself is powered through the ULP cable rather than a separate supply. Mounted on a DIN rail inside the chassis, it gives two RJ45 sockets for a daisy-chain Ethernet connection and an embedded web server for direct browser access to the breaker's data.
