1. Product Name
Allen Bradley 140G-H3F3-D16-AJ 16A Compact Miniature Contactor for Wheat Agri & Small Industrial Motor Control
2. Product Introduction
The Allen Bradley 140G-H3F3-D16-AJ is a 16A-rated Allen Bradley Miniature Contactor, designed for low-power motor control (0.5–2HP) in small wheat farm equipment and compact industrial machinery.
3. Product Description
The Allen Bradley 140G-H3F3-D16-AJ is a high-reliability Allen Bradley Miniature Contactor, part of Allen Bradley’s 140G series optimized for small-scale motor control scenarios. As a 16A-focused Allen Bradley Miniature Contactor, it precisely matches the electrical demands of low-power wheat agricultural equipment—such as 0.5HP wheat seeders, 1HP small grain winnowers, and 2HP portable wheat threshers—and compact industrial tools like 1HP bench drills or 1.5HP small belt conveyors, avoiding energy inefficiency from oversized contactors.
Constructed with UL94 V-0 flame-retardant polycarbonate housing and silver-nickel 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—essential for stable operation in small farm storage sheds or compact industrial control cabinets. Its 16A rated current aligns with the power needs of low-horsepower motors common in small wheat cultivation setups, while the compact dimensions (approx. 72×42×30mm, 115g) support standard 35mm DIN rail mounting. This design reduces control cabinet space usage by up to 35% compared to traditional low-power contactors, simplifying installation 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 -15°C to 55°C and handles up to 65% non-condensing humidity. It delivers 3 million mechanical operations and 500,000 electrical operations—sufficient for 5–12 wheat growing cycles or 6 years of continuous small-scale industrial use—significantly lowering maintenance and replacement costs.

  • Long Operational 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 low-power wheat equipment—such as portable seeders, small winnowers, and compact threshers—all relying on 0.5–2HP motors that align with the Allen Bradley 140G-H3F3-D16-AJ’s 16A capacity.
This Allen Bradley Miniature Contactor fits the site’s business model: it integrates into small wheat equipment control panels (e.g., seeder motor start-stop circuits, small thresher controls) to ensure stable performance in small farm sheds or compact workshops. The site may package the contactor with pre-assembled low-power control kits, simplifying installation for farmers with limited technical expertise. 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 16A contactor’s efficiency to enhance entry-level wheat automation, supporting farms transitioning from manual labor to basic mechanization.
7. Application Scenarios
The Allen Bradley 140G-H3F3-D16-AJ, as a 16A Allen Bradley Miniature Contactor, excels in low-power motor control:
  • Wheat Farm 0.5HP Seeders: 16A capacity matches seeder needs; dust-resistant housing prevents field debris interference during sowing seasons.

  • 1HP Small Grain Winnowers: Silver-nickel contacts handle frequent on-off cycles; compact size fits winnower control boxes in small sheds.

  • 2HP Portable Wheat Threshers: -15°C low-temp performance ensures winter wheat processing in mild cold regions without failure.

  • Industrial 1HP Bench Drills: Flame-retardant housing enhances safety in small workshops; DIN rail mounting saves cabinet space.

  • 1.5HP Small Conveyors (Wheat Chaff): Environmental resilience adapts to dusty processing; global certification works in international small farms.

  • 1.2HP Small Feed Mixers (Wheat-Based Feed): 16A current compatibility matches mixer motors; long service life reduces replacement for small-scale feed production.
