C445 Selection

The Power Xpert C445 Motor Management Relay employs a modular design with the base control module, measurement module and user interface:

  • The Base Control Module is defined by the power source (120/240 VAC or 24 VDC) and digital inputs (4 x 120 VAC or 4 x 24 VDC). In addition, the modules can also come with a Modbus Serial card installed as standard ('M' at the end of the part number).
  • The Measurement Module comes in four different styles based on what it can measure (Current Only; Current and Voltage; Current and PTC; Current, Voltage and PTC). Certain monitoring features will only be available with the more fully featured models (ex. measuring power would require both current and voltage to be measured). All models are available in frame sizes accommodating currents up to 800 Amps.
  • There are ten operation modes and twenty available User Interfaces (1 NEMA Type and 1 IEC Type per operation mode). While not required, it is recommended that choose a user interface in order to simplify wiring, software setup, and future troubleshooting scenarios.

Individual part numbers for the C445 system components can be selected from the catalog: Volume 5, Tab 5 - Motor Protection and Monitoring. You can also use the C445 Part Number Builder in order to quickly build up a C445 system.
