Product Advantages

• Reliable Motor Protection: The eutectic alloy overload relay is a proven, dependable technology that provides effective thermal protection for motors, preventing damage from overcurrent conditions.
• Robust Construction: This starter is built to withstand the rigorous demands of industrial environments, offering a long operational life.
• High Flexibility: The open-type design allows for easy integration into custom control panels and enclosures. This is ideal for machine builders and system integrators who need to customize their control systems.
• Standardized Design: As a NEMA-rated device, it adheres to industry standards, which simplifies replacement, maintenance, and system design.
• Ease of Maintenance: The modular design of the Bulletin 509 series allows for individual components, such as the coil or contacts, to be replaced without having to replace the entire starter.

Precautions

• Enclosure is Required: Because this is an “open-type” starter, it must be installed inside a proper industrial enclosure to protect it from dust, moisture, and accidental contact with live components.
• Heater Elements: The overload relay is shipped without heater elements. You must select and install three heater elements that correspond to your motor’s full-load current to ensure proper overload protection.
• Correct Sizing: Always ensure the starter’s NEMA size and current rating are appropriate for the specific motor being controlled to prevent equipment damage.
• Professional Installation: All wiring and installation should be performed by a qualified electrician in compliance with local and national electrical codes.

Product Applications

The Allen-Bradley 509-COB is used in a wide range of industrial and commercial applications for the control and protection of three-phase AC motors.

• Pumps and Compressors: Used to start and stop motors that drive pumps for fluid transfer and compressors for air or gas systems.
• Fans and Blowers: Ideal for controlling large industrial fans for ventilation and air circulation.
• Conveyor Systems: Provides reliable control for motors in material handling systems and conveyor belts.
• General Machinery: Serves as the primary control and protection for motors in various industrial machines like mixers, grinders, and machine tools.
