Allen Bradley
Allen-Bradley Contactors, Relays, Controls & Automation Parts
Allen-Bradley products are used in industrial control panels, motor control circuits, commercial equipment, automation systems, and electrical control applications where reliable switching, protection, and operator control are needed. At Gate Openers Unlimited, this page helps customers shop Allen-Bradley contactors, relays, push buttons, switches, control components, power supplies, and related replacement parts used in select commercial and industrial systems.
When ordering Allen-Bradley parts, the exact catalog number matters. Many parts are selected by bulletin series, coil voltage, amperage rating, contact arrangement, overload range, mounting style, enclosure rating, and application. Similar-looking Allen-Bradley components may not be direct replacements, especially in motor control and safety-related circuits.
Allen-Bradley Industrial Control Products
Allen-Bradley is a long-standing name in industrial automation and electrical control hardware. The brand is commonly associated with motor control components, contactors, starters, overload relays, control relays, push buttons, selector switches, pilot devices, power supplies, sensors, drives, PLC hardware, and related automation equipment.
For gate, access control, and commercial equipment applications, Allen-Bradley parts may be found in custom control panels, industrial motor circuits, commercial operator controls, machine controls, relay panels, and electrical cabinets. Because these systems vary widely, always match the part by catalog number and electrical rating before ordering a replacement.

How to Choose the Right Allen-Bradley Part
Start with the catalog number printed on the existing part. Allen-Bradley components are often part of a larger electrical control system, so the correct replacement depends on more than the outside appearance. For contactors, relays, starters, and control devices, the voltage, amperage, contact layout, and mounting style must match the original application.
- For contactors: confirm the bulletin number, coil voltage, amperage rating, number of poles, auxiliary contacts, and whether the part is IEC or NEMA style.
- For overload relays: match the overload range, compatible starter or contactor, reset style, and mounting method.
- For control relays: verify the coil voltage, contact configuration, socket or base style, and timing function if used.
- For push buttons and selector switches: check the operator type, color, legend plate, contact block arrangement, enclosure rating, and panel cutout size.
- For drives and PLC components: confirm the exact catalog number, voltage, phase, horsepower or module type, communication requirements, and programming needs.
Before Ordering Allen-Bradley Parts
- Confirm the complete Allen-Bradley catalog number from the existing part label.
- Check the bulletin number, series letter, revision, or suffix when shown.
- Verify voltage, phase, amperage, horsepower, coil rating, and contact configuration.
- Confirm whether the part is used in a motor circuit, control circuit, safety circuit, or automation system.
- Check the mounting style, enclosure rating, terminal layout, and accessory requirements.
- For overload relays, verify the motor full-load amp range and compatible starter or contactor.
- For push buttons and pilot devices, confirm color, legend, operator style, contact blocks, and enclosure requirements.
- For PLC, drive, or automation parts, confirm programming, communication, and configuration requirements before ordering.
Allen-Bradley Compatibility and Fitment Notes
Allen-Bradley compatibility depends on the exact catalog number, bulletin series, electrical rating, and system design. Two parts may appear similar but have different coil voltages, contact ratings, overload ranges, accessories, communication options, or enclosure requirements. Always compare the full catalog number and electrical specifications before replacing an Allen-Bradley component.
Older Allen-Bradley parts may have updated replacements, series changes, or Rockwell Automation cross-reference options. A newer part may require different accessories, wiring changes, programming, or additional verification before it can be used. Do not assume a replacement is drop-in unless the catalog number and application have been confirmed.
If the part is installed in a high-voltage panel, motor starter, VFD cabinet, safety circuit, fire/access control interface, or commercial gate control system, have a qualified technician or electrician verify the replacement. Do not bypass overload protection, safety circuits, interlocks, or required protective devices.

Allen-Bradley FAQ
What is Allen-Bradley commonly used for?
Allen-Bradley is commonly used for industrial control, motor control, automation, switching, relays, operator controls, drives, PLC hardware, and control-panel applications. These parts are often found in commercial equipment, industrial machinery, custom panels, and select gate or access control systems.
Is Allen-Bradley the same as Rockwell Automation?
Allen-Bradley is a hardware brand associated with Rockwell Automation. Some products, packaging, labels, or documentation may reference Rockwell Automation while the part itself is still commonly identified by the Allen-Bradley brand or catalog number.
How do I identify the correct Allen-Bradley replacement part?
Start with the complete catalog number printed on the existing part. Also check the bulletin number, series letter, voltage, amperage, coil rating, contact configuration, overload range, and mounting style. These details are important because similar-looking parts may not be interchangeable.
Are Allen-Bradley contactors interchangeable?
Not automatically. Allen-Bradley contactors must be matched by electrical rating, coil voltage, pole configuration, frame size, auxiliary contacts, overload compatibility, and mounting style. Always verify the full catalog number and application before ordering.
Can I replace an Allen-Bradley overload relay with a different range?
The overload relay range must match the motor and starter requirements. Using the wrong overload range can cause nuisance tripping or fail to protect the motor properly. Verify the motor full-load amps, starter compatibility, and reset style before replacing an overload relay.
What should I check before ordering an Allen-Bradley push button or selector switch?
Check the operator type, color, maintained or momentary function, legend plate, contact block arrangement, panel cutout size, enclosure rating, and whether the application requires a specific environmental or hazardous-location rating.
Can Allen-Bradley parts be used in gate operator systems?
Select Allen-Bradley components may be found in custom gate control panels, commercial operator controls, relay circuits, or motor control applications. Fitment depends on the exact system design, electrical ratings, and wiring requirements. A qualified technician should verify the application before replacement.
Do Allen-Bradley parts require professional installation?
Many Allen-Bradley parts are installed inside electrical panels, motor circuits, automation systems, or high-voltage equipment. Replacement should be handled by a qualified technician, electrician, or controls professional when voltage, motor control, safety circuits, programming, or unfamiliar wiring is involved.
