Description
Product Name: 500F-FOA930 Allen Bradley I/O module
Product details:
The Allen-Bradley Bulletin 500F-FOA930 is an AC Contactor designed for switching motor and non-motor loads in industrial control systems. It is part of the Bulletin 500F series, which features a Feed-Through wiring configuration, meaning the line terminals are at the top and the load terminals are at the bottom.

⭐ Product Advantages (Product Advantages)
The Bulletin 500F series contactors are valued in industrial environments for their robust design and reliable performance:
-
Heavy-Duty Performance: As a NEMA Size 5 contactor with a 270A continuous rating, it is built to handle high current, demanding motor loads, ensuring long-term reliability.
-
Durable Construction: Built with high-quality materials and silver alloy power contacts for excellent electrical conductivity and mechanical longevity.
-
Feed-Through Wiring: This specific configuration simplifies installation and maintenance by providing a standardized, clear wiring path.
-
Modular and Flexible: The design allows for easy addition of accessories, such as extra auxiliary contacts or a field-installable coil for different voltages (though the base unit has a specific coil).
-
Integrated Auxiliary Contact: Includes one N.O. auxiliary contact as standard, which is essential for control circuit interlocking and signaling.
🚨 Precautions (Notes)
When installing, operating, or servicing this device, the following safety and technical precautions are essential:
-
Safety First: Disconnect from the power source before installing or servicing the contactor to prevent electrical shock.
-
Enclosure Requirement: This is an Open Type device. It must be installed in a suitable industrial enclosure (like a cabinet or control panel) to protect personnel from live parts and protect the contactor from environmental contaminants (dust, moisture, etc.).
-
Torque Settings: Always apply the specified tightening torque to power terminal wire clamps and pressure connectors. Improper torque can lead to loose connections, overheating, and potential failure.
-
Overload Protection: A contactor is a switching device; it does not inherently provide motor overload protection. For motor applications, a separate overload relay (like a Bulletin 509 or E1 Plus) or other motor protective device must be used in conjunction with the contactor.
-
Coil Voltage: Verify that the supply control voltage matches the coil voltage rating of the contactor (220/240V AC in this case). Using the wrong voltage will damage the coil.
⚙️ Product Applications (Product Applications)
The Allen-Bradley 500F-FOA930 Contactor is primarily used as the main switching device in motor control centers and other industrial equipment. Its main applications include:
-
Motor Control: Switching 3-phase AC motor loads where overload protection is provided separately (e.g., pumps, compressors, large fans, conveyor systems).
-
Non-Motor Loads: Controlling large resistive or inductive non-motor loads, such as large heating elements or lighting circuits.
-
Capacitor Switching: Used in power factor correction applications (rated up to 80 kVAR @ 230V).
-
Transformer Primary Switching: Controlling the primary circuit of large distribution transformers.
-
Industrial Automation: Serving as the main power control element in complex machinery and manufacturing lines.
