1. Product Name

Allen Bradley 140G-H2H3-D12 12A Compact Miniature Contactor for Wheat Agri & Small Industrial Motor Control

2. Product Introduction

The Allen Bradley 140G-H2H3-D12 is a 12A-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-H2H3-D12 is a high-reliability Allen Bradley Miniature Contactor, part of Allen Bradley’s 140G series optimized for small-scale motor control. As a 12A-focused Allen Bradley Miniature Contactor, it precisely matches the electrical demands of low-power wheat agricultural equipment—such as 0.5HP wheat seeder motors, 1.5HP small grain sorters, and 2HP portable wheat chaff separators—and compact industrial tools like 1HP small exhaust fans or 1.8HP desktop sewing machines, avoiding energy waste from oversize contactors.

Constructed with UL94 V-0 flame-retardant PC housing and silver-tin alloy contacts, the Allen Bradley Miniature Contactor resists minor electrical arcing from frequent low-current on-off cycles, wheat farm dust, and light vibrations—critical for stable operation in small farm storage sheds or narrow industrial control cabinets. Its 12A rated current aligns with the low-power motors common in small-scale wheat cultivation, while the compact size (approx. 72×42×30mm, 115g) supports standard 35mm DIN rail mounting. This design saves up to 45% space in small control panels compared to traditional low-power contactors, simplifying installation for equipment with limited wiring space.

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 -25°C to 60°C and handles up to 75% 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 use—significantly reducing maintenance and replacement 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 family wheat farms, village-level grain processing units, and small industrial workshops. The site likely specializes in low-power wheat equipment—such as portable seeders, small sorters, and compact chaff separators—all relying on 0.5–2HP motors that align with the Allen Bradley 140G-H2H3-D12’s 12A 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, sorter power controls) to ensure stable performance in small farm sheds or narrow workshop spaces. The site may package the contactor with pre-wired small control kits, simplifying installation for farmers with limited technical expertise. Additionally, it might offer budget-friendly after-sales support—like basic contactor cleaning guidance and replacement tutorials—to cater to small-scale operations. This strategy leverages the 12A 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-H2H3-D12, as a 12A Allen Bradley Miniature Contactor, excels in low-power motor control:

Wheat Farm 0.5HP Seeder Motors: 12A capacity matches seeder needs; dust-resistant housing prevents field debris interference during planting.

1.5HP Small Grain Sorters: Silver-tin contacts handle frequent on-off cycles; compact size fits sorter control boxes in small sheds.

2HP Portable Wheat Chaff Separators: -25°C low-temp performance ensures winter wheat processing in cool regions without failure.

Industrial 1HP Small Exhaust Fans: Flame-retardant housing enhances safety in narrow workshops; DIN rail mounting saves cabinet space.

1.8HP Desktop Sewing Machines: Environmental resilience adapts to workshop humidity; global certification works in international small factories.

1.2HP Small Wheat Hullers: 12A current compatibility matches huller motors; long service life reduces replacement for small-scale grain processing.
