- E3 Plus 5-25 A Overload Relay
- Allen-Bradley E1 Plus enhanced electronic overload relay series
- SOLID-STATE OVERLOAD RELAY IEC E3 PLUS SIZE C09-C23
The 193-EC2CB is an E3 Plus electronic overload relay from Allen-Bradley, a brand under Rockwell Automation. It is primarily used for comprehensive protection of three-phase motors, accurately monitoring abnormalities such as overload, locked rotor, phase loss, current imbalance, and grounding faults.
As an intelligent device, it not only protects motors from overheating damage but also transmits real-time current data and diagnostic information to the control system via its built-in DeviceNet communication interface, making it a core component for realizing a Smart Motor Control Center (MCC).
The 193-EC2CB Allen Bradley Overload Relay unit may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Current Range: Adjustable full-load current (FLA) ranging from 5 to 25 amps.
- Detection: Built-in ground fault detection (typically 1 to 5 amps) for detecting low current leakage.
- Integrated I/O: Features 4 digital inputs and 2 Type-C relay outputs, allowing connection to local devices such as float switches or indicator lights without additional I/O modules.
- Mounting: Designed for direct mounting to contactors conforming to IEC 100-C23 to C30 standards.
- Intelligent Motor Protection: The 193-EC2CB employs an advanced thermal model to prevent motor overheating damage even after a power outage. It is ideal for critical three-phase motors in manufacturing, monitoring for phase loss, phase sequence imbalance, and current blockage.
- Network Automation (DeviceNet): This relay is primarily designed for DeviceNet architectures, supporting remote configuration, real-time monitoring of average current and thermal capacity (%TCU), and predictive maintenance through "trip time" reports.
- Custom Local Logic (DeviceLogix): Engineers can program custom control algorithms directly on the relay using integrated DeviceLogix technology. This is typically used to ensure smooth motor shutdown in the event of a communication interruption with the main PLC.
- Environmental and Process Monitoring: Equipped with a PTC thermistor input, this relay monitors actual winding temperature, making it suitable for motors in harsh or high-temperature environments.
