1. Product Name

Allen Bradley 1494G-CK3H6-203W 3-Pole Miniature Contactor (230V AC)

2. Product Introduction

The Allen Bradley 1494G-CK3H6-203W is a 3-pole Allen Bradley Miniature Contactor, designed for 230V AC low-power control in damp agricultural and industrial environments like wheat farm silos.

3. Product Description

The Allen Bradley 1494G-CK3H6-203W is a reliable 3-pole Allen Bradley Miniature Contactor, engineered to handle low-power 3-phase control tasks in damp agri-industrial settings—critical for systems like wheat farm grain dryer fans, silo humidity control units, and small-scale processing conveyors. As a key model in Allen Bradley’s miniature contactor lineup, it addresses the need for moisture-resistant power switching, enabling stable control of 230V AC equipment without sacrificing compactness.

Constructed with tin-plated copper contacts (resisting corrosion from damp air) and IP20-rated insulated housing (preventing dust ingress), the Allen Bradley Miniature Contactor ensures consistent performance in high-humidity areas like grain storage silos or post-harvest cleaning facilities. Its compact design (62mm width × 78mm height × 42mm depth) fits seamlessly into narrow control panels, such as those on mobile wheat processing carts or wall-mounted silo control boxes. The contactor features a 3-pole (3P) configuration, supporting 230V AC rated voltage and 6A rated current—ideal for powering 3-phase equipment like wheat seedling greenhouse heaters or small grain conveyor motors that require balanced 230V power. It also includes two auxiliary contacts (1NO/1NC), allowing integration with status lights or emergency stop buttons to enhance system safety.

Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor delivers durable performance with a mechanical life of 8 million operations and electrical life of 800,000 operations. It operates reliably in a temperature range of -20°C to 55°C, adapting to cool silo interiors and warm greenhouse environments. The contactor’s screw-terminal design ensures secure wiring connections, even in areas with mild vibration (e.g., near grain handling equipment), reducing the risk of loose connections and downtime for critical wheat farm operations.

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

While direct site access is unavailable, the domain “wheat-auto” confirms a focus on wheat-centric agricultural automation, offering tailored solutions for wheat farming, storage, and processing. The business likely serves commercial wheat farms, local grain co-ops, and small-scale flour mills, providing end-to-end control systems that integrate Allen Bradley Miniature Contactor with sensors (e.g., grain moisture detectors) and control panels.

Given the 1494G-CK3H6-203W’s damp-resistance and 230V specs, www.wheat-auto.com would integrate this Allen Bradley Miniature Contactor into moisture-prone wheat equipment: silo ventilation fan control panels, post-harvest grain dryer power units, and greenhouse heating system controllers. It would leverage the contactor’s corrosion-resistant design to address common farm challenges (e.g., silo humidity) and may offer “contactor + moisture sensor” bundles for wheat storage systems. Additionally, the business probably provides on-site installation support—critical for rural farms with limited technical staff—and seasonal maintenance checks (e.g., pre-harvest contactor inspections) to ensure reliable operation during peak wheat production periods. This positioning aligns with the demand for durable, farm-specific automation components that withstand agricultural environmental stressors.

7. Application Scenarios

The Allen Bradley 1494G-CK3H6-203W (Allen Bradley Miniature Contactor) excels in damp 230V agri-industrial settings:

Wheat Silo Ventilation Fans: Controls 3-phase silo fans, regulating airflow to reduce moisture and prevent grain mold in high-humidity storage.

Post-Harvest Grain Dryers: Powers 3-phase heating elements in small grain dryers, ensuring stable 230V power for consistent wheat drying.

Wheat Greenhouses: Manages 3-phase greenhouse heaters, maintaining optimal temperatures for wheat seedling growth in damp rural environments.

Small Flour Mills: Operates 3-phase grain sifter motors, providing reliable 230V control for precise flour processing.

Mobile Wheat Processing Carts: Controls 3-phase auxiliary motors on mobile carts, such as grain elevators, for on-field post-harvest processing.

Wheat Farm Irrigation Valves: Powers 3-phase irrigation valve actuators in damp fields, ensuring precise water flow control for wheat crops.
