Frequently Asked Questions about 193-EA1FB
Question: What is the 193-EA1FB?
Date Update:16/06/2025
Answer:

The 193-EA1FB is an electronic overload relay from Allen-Bradley’s E1 Plus series, designed to provide advanced motor protection in industrial automation systems. It protects motors from overload conditions by continuously monitoring the true RMS current of each phase. This data is used to calculate a thermal model of the motor, ensuring precise trip behavior. The relay includes built-in diagnostics and programmable trip settings. It’s ideal for smart motor control centers and integration with Logix-based systems.

Question: What trip class does it use?
Date Update:16/06/2025
Answer:

By default, the relay is set to Trip Class 10, which defines the thermal time-delay characteristics of the overload trip. However, the trip class is adjustable between 5 and 30, offering flexibility for various motor types and applications. This allows protection to be tailored for standard, high-inertia, or high-cycling motors. Trip class settings determine how quickly the relay responds to overload conditions. Accurate selection ensures both protection and motor longevity.

Question: Does it support communications?
Date Update:16/06/2025
Answer:

Yes, the 193-EA1FB is communication-enabled, supporting DeviceNet and EtherNet/IP protocols via optional modules. This allows integration with Rockwell’s Logix control systems for real-time diagnostics and control. Users can monitor parameters such as %TCU (thermal capacity utilization), phase loss, and trip history remotely. Communication enhances predictive maintenance and system transparency. It also reduces wiring complexity in large motor installations.

Question: What temperature range does it support?
Date Update:16/06/2025
Answer:

The 193-EA1FB operates reliably within a temperature range of -20°C to +40°C, making it suitable for most factory and field installations. For extended temperatures, ventilation or enclosure climate control may be required. The electronics are rated for thermal stability and protection accuracy within this range. High ambient temperatures may slightly reduce trip accuracy unless derated. The relay is designed to maintain precision in standard industrial environments.

Question: What type of protection does it offer?
Date Update:16/06/2025
Answer:

The relay provides thermal overload protection using true RMS current sensing for each phase. It calculates a dynamic thermal model of the motor to determine when an overload condition exists. It also includes thermal memory, allowing the relay to simulate cooling time when the motor is powered off. This protects against repeated quick starts that could overheat the motor. It ensures accurate protection even during power loss or restarts.
