1. Product Name

Allen Bradley 140MG-H8P-D12 Compact 120V AC Miniature Contactor

2. Product Introduction

The Allen Bradley 140MG-H8P-D12 is a high-performance Allen Bradley Miniature Contactor, engineered for 120V AC motor control in wheat agricultural and industrial setups, featuring compact design for space-constrained installations.

3. Product Description

The Allen Bradley 140MG-H8P-D12 stands as a versatile Allen Bradley Miniature Contactor, part of Allen Bradley’s 140MG series optimized for efficient low-to-mid power motor management. This Allen Bradley Miniature Contactor is tailored to meet the demands of wheat agricultural operations—such as controlling grain conveyor motors, wheat sorting machine drives, and small-scale irrigation pump systems—where space in control cabinets is limited, and reliable voltage compatibility is critical.

Constructed with high-grade thermoplastic housing (UL94 V-0 rated for flame resistance), the Allen Bradley Miniature Contactor ensures safety in warm, dusty environments common in grain processing facilities. Its silver-nickel alloy contacts minimize electrical resistance and wear, even during frequent on/off cycles—essential for equipment like intermittent grain elevator motors. The 140MG-H8P-D12 model features a 120V AC coil (indicated by the “D12” designation) and a compact form factor (approximately 72×45×28mm), allowing seamless integration into tight control panels of mobile wheat equipment or small-scale processing machines. It also includes a built-in surge suppression feature to protect against voltage spikes, a common issue in rural electrical grids powering agricultural tools.

Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor operates reliably between -20°C and 70°C, handling up to 85% non-condensing humidity. It boasts a mechanical service life of 3 million operations and an electrical service life of 700,000 operations, ensuring consistent performance across multiple wheat growing and harvesting cycles, while reducing maintenance downtime for farmers and industrial operators.
