1. Product Name

Allen Bradley 140G-H0C3-C32-UA 32A Mid-Power Miniature Contactor for Wheat Agri & Industrial Motor Control

2. Product Introduction

The Allen Bradley 140G-H0C3-C32-UA is a 32A-rated Allen Bradley Miniature Contactor, designed for mid-power motor control (2–5HP) in medium-scale wheat farm equipment and industrial machinery.

3. Product Description

The Allen Bradley 140G-H0C3-C32-UA is a high-performance Allen Bradley Miniature Contactor, part of Allen Bradley’s 140G series optimized for mid-power motor control scenarios. As a 32A-focused Allen Bradley Miniature Contactor, it precisely matches the electrical demands of medium-scale wheat agricultural equipment—such as 2HP wheat irrigation pumps, 3HP grain sieving machines, and 5HP medium grain conveyors—and industrial machinery like 4HP small mixers or 3.5HP grain cleaning equipment, avoiding overload risks from undersized contactors.

Constructed with UL94 V-0 flame-retardant ABS housing and silver-nickel alloy contacts, the Allen Bradley Miniature Contactor resists moderate electrical arcing from frequent mid-current on-off cycles, wheat field dust accumulation, and mechanical vibrations—essential for stable operation in medium farm workshops or industrial control panels. Its 32A rated current is tailored for mid-power motors common in medium wheat cultivation setups, while the compact size (approx. 82×48×35mm, 150g) supports standard 35mm DIN rail mounting. This design saves up to 35% space in control cabinets compared to traditional mid-power contactors, reducing on-site installation time for medium-sized 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 -25°C to 65°C and handles up to 75% non-condensing humidity. It delivers 3 million mechanical operations and 500,000 electrical operations—sufficient for 3–8 wheat growing cycles or 6 years of continuous mid-scale industrial use—greatly lowering maintenance and replacement costs.

6. Business Insight on www.wheat-auto.com

While direct access is unavailable, www.wheat-auto.com’s domain confirms its focus on wheat-centric agricultural automation, targeting medium-scale wheat farms, regional grain processing facilities, and small industrial workshops. The site likely specializes in medium-power wheat equipment—such as irrigation pump systems, grain sieving machines, and medium conveyors—all relying on 2–5HP motors that align with the Allen Bradley 140G-H0C3-C32-UA’s 32A capacity.

This Allen Bradley Miniature Contactor fits the site’s business model: it integrates into mid-power wheat equipment control systems (e.g., irrigation pump start-stop circuits, grain sieve motor controls) to ensure stable performance in dusty farm and industrial environments. The site may package the contactor with pre-wired mid-scale control panels, simplifying installation for farmers and workshop operators with basic technical skills. Additionally, it might offer seasonal after-sales support—like pre-planting contactor inspections and post-harvest maintenance—to minimize downtime for medium-scale wheat operations. This strategy leverages the 32A contactor’s reliability to enhance mid-level wheat automation efficiency, catering to farms transitioning from small-scale to medium-scale mechanization.

7. Application Scenarios

The Allen Bradley 140G-H0C3-C32-UA, as a 32A Allen Bradley Miniature Contactor, excels in mid-power motor control:

Wheat Farm 2HP Irrigation Pumps: 32A capacity matches pump motors; dust-resistant housing prevents field debris interference during watering seasons.

3HP Grain Sieving Machines: Silver-nickel contacts handle frequent on-off cycles; compact size fits sieving machine control boxes.

5HP Medium Grain Conveyors: -25°C low-temp performance ensures winter wheat transport in cold regions without operational failure.

Industrial 4HP Small Mixers: Flame-retardant housing enhances safety in workshop settings; DIN rail mounting saves control cabinet space.

3.5HP Grain Cleaning Equipment: Environmental resilience adapts to dusty processing environments; global certification works in international medium farms.

4.5HP Feed Mixers (Wheat By-Product Processing): 32A current compatibility matches mixer motors; long service life reduces replacement needs for continuous processing.
