PRODUCT DESCRIPTION
Product Description
Allen-Bradley electronic overload relays are designed to protect motors from overload conditions, preventing damage to the motor and associated equipment. These devices continuously monitor the motor
current and trip if the current exceeds a preset threshold. They are typically integrated into motor control circuits along with contactors.
Key Features and Specifications
Trip Classes: Available in various trip classes (e.g., 10, 20, 30) to match different motor types and applications.
Adjustable Trip Settings: The trip current can be adjusted to match the motor's full-load current.
Contact Configuration: Typically have normally open and normally closed contacts for controlling external circuits.
Mounting:Can be mounted directly to contactors or on a panel.
Reset: Manual or automatic reset options are available.
Advantages
Precise Protection: Provides accurate and reliable motor protection.
Adjustable Trip Settings: Can be customized to match specific motor requirements.
Compact Design: Saves space in control panels.
Easy Installation: Simple to install and wire.
Compatibility: Compatible with a wide range of Allen-Bradley contactors.
Precautions
Proper Selection: Ensure the overload relay is selected based on the motor's full-load current and trip class.
Mounting: Securely mount the relay to prevent vibration and ensure proper operation.
Wiring: Correctly wire the relay according to the manufacturer's instructions.
Environment: Avoid exposing the relay to extreme temperatures, humidity, or corrosive environments.
Calibration: Periodic calibration may be required to maintain accuracy.
Applications
Allen-Bradley electronic overload relays are used in a wide range of applications, including:
Industrial Automation: Protecting motors in manufacturing processes.
HVAC Systems: Protecting motors in HVAC equipment.
Pumping Systems: Protecting motors in pumping applications.
Material Handling: Protecting motors in conveyor systems and material handling equipment.
Additional Features and Considerations
Phase Loss Protection: Some models offer additional protection against phase loss.
Ground Fault Protection: Certain models can detect ground faults.
Communication: Some advanced models may have communication capabilities for integration into automation systems.
For specific product information and selection, refer to the Allen-Bradley product catalog or consult with a Rockwell Automation representative.
Key Considerations When Selecting an Overload Relay:
Motor characteristics: Full-load current, starting current, and type of motor.
Environment: Operating temperature, humidity, and potential contaminants.
