2. Product Introduction
The Allen Bradley 140G-J3F3-C80-KA is a high-power Allen Bradley Miniature Contactor, engineered to handle heavy-duty motor control in large-scale wheat agricultural equipment and industrial machinery.
3. Product Description
The Allen Bradley 140G-J3F3-C80-KA is a heavy-duty Allen Bradley Miniature Contactor, part of Allen Bradley’s industry-leading 140G series optimized for high-power motor control. This Allen Bradley Miniature Contactor stands out for its ability to manage 15–25HP motor loads, making it a perfect fit for large-scale wheat agricultural scenarios—such as 20HP wheat harvester main motors, 18HP large grain silo conveyor motors, and 22HP wheat drying system fans—as well as industrial applications like 25HP wheat flour mill grinding motors.
Constructed with a dual-layer reinforced thermoplastic housing (compliant with UL94 V-0 flame-retardant standards), the Allen Bradley Miniature Contactor offers superior resistance to dust, high vibration, and moderate moisture—addressing the harsh conditions of large wheat farms and industrial processing plants. Its gold-plated silver-alloy electrical contacts minimize contact resistance and enhance arc suppression during high-current motor start/stop cycles, protecting both the contactor and connected motors from electrical damage. With a space-efficient design (approximately 95×62×40mm), the Allen Bradley Miniature Contactor supports 35mm DIN rail mounting, enabling easy integration into crowded control cabinets and reducing installation complexity for on-site technicians.
Compliant with international standards including IEC 60947-4-1 and UL 508, this Allen Bradley Miniature Contactor operates reliably within a temperature range of -30°C to 75°C and handles up to 85% non-condensing humidity. It boasts a mechanical service life of 3 million operations and an electrical service life of 600,000 operations, ensuring long-term durability through years of continuous wheat farming cycles and industrial use—significantly reducing maintenance frequency and replacement costs.
