Schneider Electric LV851200SP MasterPact MTZ2/3 EIFE Ethernet Interface Drawout Air Circuit Breaker Accessory

The Schneider Electric LV851200SP is an EIFE embedded Ethernet interface module for drawout MasterPact MTZ2 and MTZ3 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 LV851200SP covers the larger MTZ2/MTZ3 frames, while the LV851100SP is the MTZ1-only version; both share identical electrical and communication specifications. It requires a ULP communication port already fitted on the chassis — use the LV850062SP ULP port module on a drawout MTZ2/MTZ3 breaker — since the EIFE draws its power from the ULP cable rather than a separate supply. The same DIN-rail mounting, dual RJ45 daisy-chain ports, and embedded web server apply as on the MTZ1 module.
