The GE Multilin LM10 Low Voltage Motor Protection System is a modular device for low voltage motor protection. The compact design of the LM10 is ideally suited for Low Voltage Motor Control Center applications but can also be used in standalone applications. The LM10 comes standard with the DeviceNet protocol that allows the user to control and monitor the relay over a network. The relay also has an interface port to communicate with the optional LM10 Programmable Display Unit (PDU). This display unit allows for local programming and monitoring of the relay. Matched sets of three phase Current Transformers (CT) and one ground CT are also available as part of the LM10 package.
