1. Product Name
Allen Bradley 1492-ACABLE140UB Miniature Contactor
2. Product Introduction
The Allen Bradley 1492-ACABLE140UB is a high-capacity Allen Bradley Miniature Contactor, designed for 140A heavy-load control in large-scale wheat agricultural systems and medium-to-heavy industrial setups, ensuring stable power management.
3. Product Description
The Allen Bradley 1492-ACABLE140UB is a heavy-duty Allen Bradley Miniature Contactor, part of Allen Bradley’s 1492 series engineered for high-current mid-to-heavy load control—filling the gap between standard miniature contactors and industrial contactors. This Allen Bradley Miniature Contactor is tailored for large-scale wheat agricultural operations, such as controlling high-power wheat grain elevator motors, large silo ventilation fans, and industrial-grade wheat washing machine drives, as well as medium-to-heavy industrial applications like large packaging line conveyors and warehouse refrigeration compressor circuits.
Constructed with heat-resistant ceramic-insulated housing and gold-plated copper alloy contacts, the Allen Bradley Miniature Contactor minimizes electrical resistance, reduces heat generation during high-current operation, and withstands prolonged use in dusty wheat processing plants and high-temperature industrial workshops. Its optimized dimensions (approximately 85×55×32mm) balance high-current capacity with space efficiency, enabling installation into standard control panels of large agricultural equipment—such as 100-ton-capacity wheat grain elevators or industrial wheat flour milling machines. The 1492-ACABLE140UB supports a rated current of 140A (at 480V AC) and is compatible with 120V AC/240V AC control voltages, making it ideal for heavy-power agricultural and industrial systems that demand reliable on-off control for high-load motors. It also integrates dual overload protection mechanisms (thermal and magnetic) to safeguard against current spikes and motor overheating—critical for unstable rural power grids common in large wheat farms.
Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor operates efficiently within a temperature range of -25°C to 70°C and can handle up to 90% non-condensing humidity. It boasts a mechanical service life of 1.5 million operations and an electrical service life of 300,000 operations, ensuring long-term durability across multiple wheat growing and harvesting cycles while reducing maintenance frequency for large-scale farm and industrial operators.

5. Product Advantages
  • High 140A Capacity: Handles heavy loads like large wheat grain elevator motors, avoiding the need for bulky industrial contactors.

  • Dual Overload Protection: Thermal + magnetic safeguards prevent motor burnout from rural power grid fluctuations and debris jams in wheat equipment.

  • Heat-Resistant Build: Ceramic-insulated housing withstands 70°C high temperatures in wheat drying facilities and industrial workshops.

  • Voltage Versatility: 120V AC/240V AC compatibility fits diverse agricultural/industrial power systems, reducing integration costs.

  • Space-Efficient Design: 85×55×32mm size fits standard control panels of large wheat equipment, saving installation space.

  • Durable Contacts: Gold-plated copper alloy minimizes arcing and wear, extending service life in dusty wheat processing environments.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms a focus on large-scale wheat agricultural automation—catering to commercial wheat farms (1000+ acres), regional grain processing centers, and industrial flour mills. The business likely offers end-to-end heavy-duty solutions: 100-ton grain elevators, industrial wheat washing lines, and large silo storage control systems—all requiring high-current components like the Allen Bradley 1492-ACABLE140UB.
Given the contactor’s 140A capacity and dual overload protection, www.wheat-auto.com would integrate it into high-power wheat equipment: grain elevator main motors (handling 50+ tons/hour wheat transport), industrial wheat cleaner drives (with debris-jam risk), and large silo ventilation fans (running 24/7 for grain preservation). It would leverage the contactor’s compliance with agricultural standards (e.g., ISO 23387 for heavy grain handling) to address large-farm pain points—unstable rural power (via dual overload protection) and high-temperature drying environments (via 70°C resilience). Additionally, the business probably provides farm-specific support: custom control panel design for elevators, power load testing, and maintenance training for large-equipment operators. This alignment with “industrial-grade smart agriculture” uses the Allen Bradley Miniature Contactor to boost large-scale wheat production efficiency while mitigating high-load operational risks.
7. Application Scenarios
The Allen Bradley 1492-ACABLE140UB, as a high-capacity Allen Bradley Miniature Contactor, excels in heavy-load agri/industrial settings:
  • Large Wheat Grain Elevators: Controls main motors of 50-ton/hour elevators, 140A capacity matching the equipment’s high-power demand.

  • Industrial Wheat Washing Lines: Manages drive motors of 1000kg/hour wheat cleaners, dual overload protection preventing burnout from debris clogs.

  • Large Silo Ventilation Systems: Regulates 24/7 running fan motors in 500-ton wheat silos, heat resistance handling fermentation-induced high temperatures.

  • Heavy-Duty Flour Mills: Controls grinding motor of industrial flour mills (producing 50+ tons/day flour), durable contacts withstanding continuous operation.

  • Agricultural Irrigation Pumps (Large Farms): Operates 100HP irrigation pumps for 1000-acre wheat fields, voltage versatility fitting farm power systems.

  • Industrial Packaging Lines (Grain): Manages conveyor motors of 200-bag/hour wheat packaging lines, space-efficient design fitting control panels of large production lines.
