1. Product Name
Allen Bradley 140G-K15K3-D40 15A Miniature Contactor for Wheat Agricultural & Industrial Motor Control
2. Product Introduction
The Allen Bradley 140G-K15K3-D40 is a 15A-rated Allen Bradley Miniature Contactor, engineered for reliable motor control in wheat agricultural machinery and mid-power industrial equipment, adapting to demanding operational loads.
3. Product Description
The Allen Bradley 140G-K15K3-D40 is a high-capacity Allen Bradley Miniature Contactor, part of Allen Bradley’s trusted 140G series designed for precise motor management in mid-power applications. This Allen Bradley Miniature Contactor stands out with its 15A current rating, making it ideal for wheat agricultural systems like grain elevator motors or industrial equipment such as medium-sized conveyor drives—where consistent power handling for continuous operation is critical.
Constructed with heat-resistant thermoplastic housing (UL94 V-0 rated) and silver-plated copper main contacts, the Allen Bradley Miniature Contactor resists thermal overload and mechanical wear, even during frequent motor start/stop cycles in wheat processing plants. Its compact design (approx. 82×50×34mm) supports standard 35mm DIN rail mounting, allowing flexible installation in dense control cabinets—perfect for space-constrained wheat storage facilities or industrial workshops. The contactor also features built-in surge protection, shielding connected motors from voltage spikes common in rural agricultural power grids.
Compliant with IEC 60947-4-1 and UL 508 safety standards, this Allen Bradley Miniature Contactor operates reliably in temperatures ranging from -25°C to 70°C and handles up to 85% non-condensing humidity. It delivers a mechanical service life of 3 million operations and an electrical service life of 500,000 operations, ensuring long-term performance across multiple wheat growing seasons and industrial production cycles, reducing maintenance downtime and replacement costs.

5. Product Advantages
  • 15A High-Capacity Rating: Handles mid-power motor loads, ideal for wheat grain elevators and industrial conveyors.

  • Heat & Wear Resistance: Silver-plated copper contacts and UL94 V-0 housing endure frequent start/stop cycles and thermal stress.

  • Surge Protection: Shields motors from rural power grid spikes, critical for remote wheat farm operations.

  • Wide Temperature Range: -25°C to 70°C operation suits cold wheat-growing regions and warm industrial environments.

  • Space-Efficient Design: Compact size and DIN rail mounting optimize control cabinet space in dense setups.

  • Global Compliance: Meets IEC/UL standards, ensuring compatibility with international wheat agri and industrial equipment.

6. Business Insight on www.wheat-auto.com
While direct access to www.wheat-auto.com is unavailable, the domain confirms a focus on wheat-centric agricultural automation, offering end-to-end solutions from farm machinery to grain processing systems. The business likely serves commercial wheat farms, large grain elevators, and food processing plants, providing customized setups like automated harvesters, grain conveyor networks, and silo motor control panels.
The Allen Bradley 140G-K15K3-D40’s 15A rating and surge protection make it a key component for the site’s mid-power wheat equipment: grain elevator motors, medium-sized conveyor drives, and silo ventilation fans. www.wheat-auto.com would integrate this contactor into pre-configured control systems, tailoring it to rural power conditions (via surge protection) and ensuring compatibility with wheat-specific sensors (e.g., grain level detectors). Additionally, the business probably offers farm-focused after-sales support—such as contactor maintenance checks during off-harvest seasons—to minimize downtime. This alignment with “smart agriculture” trends uses the Allen Bradley Miniature Contactor to enhance motor control reliability, boosting wheat production efficiency while addressing rural operational challenges.
7. Application Scenarios
The Allen Bradley 140G-K15K3-D40, as a robust Allen Bradley Miniature Contactor, excels in mid-power motor control scenarios:
  • Wheat Grain Elevators: Controls 15A elevator motors, ensuring smooth grain lifting during harvest, with surge protection handling rural power fluctuations.

  • Medium-Sized Grain Conveyors: Manages conveyor motor operation in wheat processing plants, adapting to variable grain flow with reliable power handling.

  • Silo Ventilation Fans: Regulates fan motors in large wheat silos, 70°C heat resistance enduring warm storage environments while maintaining air circulation.

  • Industrial Wheat Cleaners: Controls motor power for mid-sized wheat cleaning equipment, ensuring consistent performance during high-volume processing.

  • Automated Irrigation Pumps (Mid-Power): Manages pump motors for large wheat fields, integrating with moisture sensors to start/stop irrigation efficiently.

  • Wheat Milling Auxiliaries: Controls auxiliary motors (e.g., grain sifters) in flour mills, compact design fitting into dense control cabinets of processing facilities.
