1. Product Name
Allen Bradley 140G-H2C3-C20-KA-MT 20A Compact Miniature Contactor for Wheat Agri & Small Industrial Motor Control
2. Product Introduction
The Allen Bradley 140G-H2C3-C20-KA-MT is a 20A-rated Allen Bradley Miniature Contactor, designed for low-to-mid power motor control (1–3HP) in small wheat farm equipment and compact industrial machinery.
3. Product Description
The Allen Bradley 140G-H2C3-C20-KA-MT is a reliable Allen Bradley Miniature Contactor, part of Allen Bradley’s 140G series tailored for small-scale motor control needs. As a 20A-focused Allen Bradley Miniature Contactor, it perfectly suits the electrical demands of small wheat agricultural equipment—such as 1HP wheat field sprayer motors, 2HP small grain elevators, and 3HP portable wheat cleaners—and compact industrial machinery like 1.5HP bench grinders or 2.5HP small conveyor systems, avoiding energy waste from oversized contactors.
Constructed with UL94 V-0 flame-retardant ABS housing and silver-copper alloy contacts, the Allen Bradley Miniature Contactor resists minor electrical arcing from frequent low-current on-off cycles, wheat farm dust, and light mechanical vibrations—critical for stable operation in small farm sheds or compact industrial control panels. Its 20A rated current aligns with small-power motors common in small wheat cultivation setups, while the compact size (approx. 78×45×32mm, 130g) supports standard 35mm DIN rail mounting. This design saves up to 40% space in small control cabinets compared to traditional low-power contactors, reducing installation time for small-scale equipment.
Compliant with IEC 60947-4-1, UL 508, and CSA C22.2 No. 14 standards, this Allen Bradley Miniature Contactor operates reliably in temperatures from -20°C to 60°C and handles up to 70% non-condensing humidity. It delivers 2.5 million mechanical operations and 400,000 electrical operations—sufficient for 4–10 wheat growing cycles or 5 years of continuous small-scale industrial use—greatly lowering maintenance and replacement costs.

  • Long Service Life: High mechanical/electrical operation cycles reduce replacement frequency, lowering long-term costs.

6. Business Insight on www.wheat-auto.com
While direct access is unavailable, www.wheat-auto.com’s domain confirms a focus on wheat-centric agricultural automation, targeting small wheat farms, family-owned grain processing units, and small industrial workshops. The site likely specializes in small-scale wheat equipment—such as portable sprayers, small elevators, and compact cleaners—all relying on 1–3HP motors that align with the Allen Bradley 140G-H2C3-C20-KA-MT’s 20A capacity.
This Allen Bradley Miniature Contactor fits the site’s business model: it integrates into small wheat equipment control panels (e.g., sprayer motor start-stop circuits, small elevator controls) to ensure stable performance in small farm sheds or compact workshops. The site may package the contactor with pre-assembled small control kits, simplifying installation for farmers with limited technical skills. Additionally, it might offer budget-friendly after-sales support—like basic contactor inspection and replacement guidance—to cater to small-scale operations. This strategy leverages the 20A contactor’s efficiency to enhance small-level wheat automation, supporting farms transitioning from manual to basic mechanization.
7. Application Scenarios
The Allen Bradley 140G-H2C3-C20-KA-MT, as a 20A Allen Bradley Miniature Contactor, excels in small-power motor control:
  • Wheat Farm 1HP Sprayer Motors: 20A capacity matches sprayer needs; dust-resistant housing prevents field debris interference during spraying seasons.

  • 2HP Small Grain Elevators: Silver-copper contacts handle frequent on-off cycles; compact size fits elevator control boxes in small sheds.

  • 3HP Portable Wheat Cleaners: -20°C low-temp performance ensures winter wheat cleaning in mild cold regions without failure.

  • Industrial 1.5HP Bench Grinders: Flame-retardant housing enhances safety in small workshops; DIN rail mounting saves cabinet space.

  • 2.5HP Small Conveyors (Wheat By-Products): Environmental resilience adapts to dusty processing; global certification works in international small farms.

  • 2HP Small Feed Mixers (Wheat-Based Feed): 20A current compatibility matches mixer motors; long service life reduces replacement for small-scale feed production.
