How do I select a C441 Motor Insight Relay?

Selecting a C441 Motor Insight Relay is based on the motor FLA and power source for the relay. The relay can be used to monitor voltages from 170 to 660 VAC and currents from 1 to 540 Amps. Available power sources for the relay include 120, 240, 480 and 600 VAC. Note that the 120 VAC control powered relay does not include a user interface, but a separate remotely mounted interface can be used (including a NEMA 3R option). Communication modules are also available for Ethernet/IP, Modbus TCP, DeviceNet, and PROFIBUS.

See the catalog for selecting individual catalog numbers: Volume 5, Tab 5 - Motor Protection and Monitoring
