1. Product Name
Allen Bradley 105-C09AH-OLR-1-4GW Overload-Protected Miniature Contactor
2. Product Introduction
The Allen Bradley 105-C09AH-OLR-1-4GW is an overload-protected Allen Bradley Miniature Contactor, optimized for low-voltage motor control in wheat farm automation and industrial settings, safeguarding motors from overload damage.
3. Product Description
The Allen Bradley 105-C09AH-OLR-1-4GW is a precision-engineered Allen Bradley Miniature Contactor, part of Allen Bradley’s 105 series dedicated to safe, efficient low-voltage motor control. As a specialized Allen Bradley Miniature Contactor with built-in overload protection (OLR), it excels at controlling and safeguarding small-to-medium motors—including wheat farm irrigation pumps, grain conveyor motors, and industrial bench-top processing equipment—effectively preventing motor burnout caused by current surges or prolonged overloads in dusty, high-cycle environments.
With a compact design (approx. 72×48×35mm), this Allen Bradley Miniature Contactor fits easily into narrow control cabinets, a critical advantage for space-constrained wheat farm silo panels or industrial machines with limited installation room. It supports low-voltage operations, compatible with 24V DC control voltage (matching portable wheat farm equipment power systems) and suitable for motors up to 2.2kW at 400V AC. The contactor uses silver-tin oxide contacts to reduce electrical resistance and enable efficient arc extinguishing, minimizing wear even during frequent switching—essential for wheat farming tasks like periodic irrigation activation or industrial production cycles. Its integrated overload relay automatically cuts power when current exceeds safe limits, adding an extra layer of motor protection beyond standard contactors.
Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor meets global safety and performance requirements. It boasts dust-resistant housing to handle grain debris in wheat farms and vibration resistance (up to 50Hz, 1.5g) to withstand movement from mobile agricultural equipment. With a mechanical service life of over 10 million operations and an electrical life of 1 million operations, it delivers long-term reliability for both agricultural and industrial motor control needs.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, its domain “wheat-auto” confirms a focus on wheat-centric agricultural automation solutions—supplying, integrating, and supporting equipment for wheat farming, from irrigation and harvesting to grain storage and processing.
This Allen Bradley Miniature Contactor would be a core component in the site’s offerings, as its overload protection addresses a key pain point in wheat farming: motor damage from variable loads (e.g., clogged grain conveyors or uneven irrigation pump pressure). www.wheat-auto.com likely packages the contactor into “farm-ready” kits—paired with control panels, sensors, and wiring—for easy installation in rural wheat farms. It may also provide agricultural-specific after-sales support, such as overload threshold calibration for different motor types (irrigation vs. conveyor) and dust maintenance guidance. By integrating industrial-grade, overload-protected components like this Allen Bradley Miniature Contactor, the business aligns with “smart agriculture” trends, boosting wheat farming efficiency while reducing costly motor replacement downtime.
7. Application Scenarios
The Allen Bradley 105-C09AH-OLR-1-4GW, as a specialized Allen Bradley Miniature Contactor, excels in overload-prone low-voltage motor control scenarios:
  • Wheat Farm Irrigation Pumps: Overload protection prevents burnout when pumps encounter debris clogs, while 24V DC compatibility matches portable pump systems.

  • Grain Conveyors: Automatically cuts power if wheat grain clogs the conveyor, protecting the motor from prolonged overload during harvest.

  • Wheat Seeders: Controls seed-distribution motors, with OLR safeguarding against damage from clumped seeds that increase motor load.

  • Industrial Flour Mixers: Manages low-voltage motors of bench-top mixers in wheat processing plants, preventing overload from thick dough batches.

  • Silo Ventilation Fans: Overload protection ensures fan motors don’t burn out from dust buildup, while compact design fits silo control cabinets.

  • Portable Harvester Auxiliaries: Powers 24V DC sensors and small motors on wheat harvesters, with vibration resistance handling equipment movement.
