by

The allen bradley ab-193-eecb is an IEC‑rated E1 Plus enhanced electronic overload relay designed to protect three‑phase motors with an adjustable current range of 1–5 A and both manual and automatic reset options. Select a Region | Rockwell AutomationPrdsccdnstorage. Compact and self‑powered, this relay provides reliable trip protection without requiring a separate power supply.

Key Features of the Allen Bradley AB-193‑EECB

  • Adjustable Current Range (1.0–5.0 A): A wide 5:1 span minimizes inventory needs by covering multiple motor sizes.

  • Selectable Trip Class: Choose between Class 10, 15, 20, 30 for tailored overload response.

  • Manual & Automatic Reset: Offers the flexibility to reset trips manually or automatically after a fault.

  • Phase Loss Protection: Detects single‑phase conditions to prevent motor damage.

  • Self‑Powered Design: No external supply needed; draws power directly from the monitored circuit.

  • Integrated Mounting: Features both DIN‑rail and panel‑mount holes for versatile installation without extra adapters.

  • Low Heat Generation: Efficient solid‑state design reduces panel temperature and extends component life.

Applications and Compatibility

The AB‑193‑EECB is engineered for motor protection in industrial environments. Common use cases include:

  • Integration with 100‑C09 to C23 IEC contactors for streamlined motor starter assemblies.

  • Retrofit into existing panels in place of older thermal relays, leveraging its compact footprint to save up to 48% panel space, Rockwell Automation.

  • Protection for motors using external current transformers in specialized installations.

Installation & Wiring Tips

  1. Mounting: Snap onto standard DIN rails or secure with screws using the built‑in panel‑mount holes.

  2. Connections:

    • Line & Load Terminals: Tighten to manufacturer torque specs.

    • Reset Selector: Wire according to the desired manual or auto‑reset function.

  3. Testing: After wiring, perform a trip test at a simulated overload (110% of maximum current) to verify correct operation.

  4. Maintenance: Inspect terminals periodically for tightness and check for any signs of overheating.

For detailed wiring diagrams and installation instructions, refer to the Rockwell Automation Bulletin 193‑IN026.

Lifecycle & Replacement

Rockwell Automation discontinued the 193‑EECB on July 31, 2021. Customers are advised to transition to the direct replacement model 193‑1EFCB or the newer E100™ Electronic Overload Relay series for enhanced accuracy and longevity.

Frequently Asked Questions

  1. What is the Allen Bradley AB-193‑EECB used for?
    It’s an electronic overload relay that protects three‑phase motors by monitoring current and tripping on overloads, phase loss, or ground faults.

  2. What is the current adjustment range of the AB-193‑EECB?
    The relay covers a wide 1.0–5.0 A range, allowing one device to protect multiple motor sizes.

  3. Can I mount the AB-193‑EECB without additional adapters?
    Yes—its integrated DIN‑rail and panel‑mount design eliminates the need for separate mounting hardware.

  4. Is the AB-193‑EECB still available for purchase?
    No—it was discontinued on July 31, 2021. The recommended replacement is the 193‑1EFCB or the E100™ series.

  5. How do I test the AB-193‑EECB after installation?
    Perform a calibrated trip test at 110% of the max current setting and verify that the relay trips and resets correctly, according to Bulletin 193‑IN026 installation guidelines
