Oct. 30 , 2025
1. Product Name
Allen Bradley 105-C09AA-OLR-4RG Miniature Contactor with Built-in Overload Protection (OLR)
2. Product Introduction
The Allen Bradley 105-C09AA-OLR-4RG is a specialized Allen Bradley Miniature Contactor integrated with overload protection (OLR), designed for 9A low-to-medium current control. It safeguards motors in industrial and wheat farm automation from overload damage.
3. Product Description
The Allen Bradley 105-C09AA-OLR-4RG is a feature-rich Allen Bradley Miniature Contactor, part of Allen Bradley’s 105 series optimized for safe, efficient current control—with a key advantage: built-in overload protection (OLR). As a critical Allen Bradley Miniature Contactor for motor safety, it excels at switching circuits for small motors (e.g., wheat farm irrigation pumps, industrial conveyor motors) while automatically cutting power if current exceeds safe limits, preventing burnout.
With a compact footprint (68×45×32mm), this Allen Bradley Miniature Contactor fits into tight control cabinets—ideal for wheat farm silo auxiliary panels or industrial bench-top equipment where space is limited. It supports a rated current of 9A at 400V AC and is compatible with common control voltages (24V DC/110V AC/230V AC), adapting to diverse automation setups. The contactor uses silver-tin oxide contacts for low resistance, strong arc extinguishing, and dust resistance—critical for dusty wheat grain-handling environments or industrial workshops with debris.
Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor meets global safety requirements. Its OLR function is calibrated to detect 1.5× rated current (13.5A) within 10 seconds, providing fast protection for motors prone to overload (e.g., wheat conveyor motors jammed by grain). It also integrates surge protection to shield sensitive devices like wheat moisture sensors. With a mechanical life of 10 million operations and electrical life of 1 million operations, it ensures long-term reliability for frequent-switching tasks.

5. Product Advantages
  • Built-in OLR Protection: Automatically cuts power at 1.5× rated current, preventing motor burnout in wheat farm/industrial applications (e.g., jammed conveyors).

  • 9A Current Suitability: Perfect for small-to-mid-sized loads (e.g., 0.5-2kW motors), bridging micro and standard contactors.

  • Space-Saving Design: 68×45×32mm size fits narrow cabinets, ideal for wheat farm small equipment or industrial bench setups.

  • Dust-Resistant Contacts: Silver-tin oxide material withstands grain dust, reducing contact failure in agricultural environments.

  • Global Compliance: Meets IEC/UL standards, enabling use in international wheat farms and industrial projects.

  • Low Maintenance: 10M mechanical/1M electrical operations + OLR durability lower replacement and repair costs.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms www.wheat-auto.com focuses on wheat-centric agricultural automation, offering end-to-end solutions for wheat production (irrigation, grain transport, storage) and auxiliary processing.
The Allen Bradley 105-C09AA-OLR-4RG, as an OLR-equipped Allen Bradley Miniature Contactor, is a core safety component for the site’s product lineup. It addresses a key wheat farm pain point: motor overload from grain jams (e.g., conveyor blockages) or voltage fluctuations. The site would position this contactor for critical small-motor equipment: portable wheat irrigation pumps (preventing overload from dry soil), mini grain conveyors (guarding against grain jams), and small drying unit motors. It may bundle the contactor with custom “motor safety kits” (paired with wheat moisture sensors or jam detectors) to create turnkey solutions for small-to-medium wheat farms. Additionally, www.wheat-auto.com likely offers agricultural-specific support—such as OLR calibration guidance for farm motors or dust-proof installation tips—to ensure optimal performance in grain-handling environments. This aligns with “smart agriculture” trends, using the contactor’s OLR feature to enhance equipment safety and reduce wheat farm downtime.
7. Application Scenarios
The Allen Bradley 105-C09AA-OLR-4RG, a safety-focused Allen Bradley Miniature Contactor, excels in motor-protection-critical scenarios:
  • Wheat Irrigation Pumps: Protects 9A portable pump motors from overload (e.g., dry soil causing pump strain), cutting power to prevent burnout.

  • Mini Grain Conveyors: Shields conveyor motors from overload due to grain jams, automatically stopping power to avoid motor damage.

  • Small Wheat Dryers: Guards heating fan motors in compact drying units, preventing overload from clogged air filters (common in dusty grain environments).

  • Wheat Cleaning Sifters: Protects small sifter motors from overload when screens are blocked by debris, ensuring consistent cleaning without motor failure.

  • Industrial Small Mixers: Safeguards motor in small wheat flour mixers from overload due to thick dough, maintaining production continuity.

  • Farm Auxiliary Motors: Protects small motor-driven equipment (e.g., wheat seeders) from voltage fluctuations, ensuring reliable operation during planting seasons.
