- Motor Control Centers (MCC) with DeviceNet backbone
- Conveyor and material handling systems
- Pump and fan motor protection panels
- HVAC and building automation control cabinets
- Food & beverage processing lines requiring IEC/UL dual-listed components
- Oil & gas upstream/downstream motor protection
System Compatibility
- PLC Platforms: Allen-Bradley ControlLogix, CompactLogix, MicroLogix (via DeviceNet scanner)
- Contactors: Allen-Bradley 100-C09 through 100-C85 series
- Network: DeviceNet (EDS file available from Rockwell Automation)
- Software: RSNetWorx for DeviceNet, Studio 5000 Logix Designer
Selection Guide
Use the table below to select the correct 193-EEF_ suffix based on your motor’s Full Load Amperage (FLA):
- 193-EEFB: Lower FLA range — suitable for smaller motors
- 193-EEFC: Mid FLA range — general-purpose applications
- 193-EEFD: Standard FLA range — most common industrial motors ✅ This model
- 193-EEFE: Higher FLA range — larger motors and heavy-duty loads
If your application requires without DeviceNet, consider the 592-E series (E1 Plus). For standalone (non-networked) protection, the 193-T series thermal overload may be sufficient.

Replacement & Compatibility FAQ
Q: Can I replace 193-EEFD with 193-EEFC?
A: Only if your motor FLA falls within the 193-EEFC range. The mounting and wiring are identical, but the trip current range differs.
Q: Does 193-EEFD work without a DeviceNet network?
A: Yes. It operates as a standalone overload relay; DeviceNet connectivity is optional.
Q: Is the 193-EEFD compatible with IEC contactors from other brands?
A: Direct-mount is designed for Allen-Bradley 100-C series. Panel-mount adapters allow use with other contactor brands.
Q: What is the difference between 193-EEFD and 592-EEFD?
A: The 193-E series (E3 Plus) includes DeviceNet communication; the 592-E series (E1 Plus) does not. Both share similar protection features.
Q: Can Konmask.com provide a datasheet or wiring diagram?
A: Yes. Contact us at support@konmask.com with your part number and we will provide the relevant documentation.
