1. Product Name

Allen Bradley 140G-NS0H4-E12 Miniature Contactor for Wheat Agricultural & Industrial Mid-Power Motor Control

2. Product Introduction

The Allen Bradley 140G-NS0H4-E12 is a high-reliability Allen Bradley Miniature Contactor, designed for precise mid-power motor regulation in wheat agricultural equipment (e.g., grain conveyors, irrigation pumps) and industrial systems, ensuring stable operation and easy integration.

3. Product Description

The Allen Bradley 140G-NS0H4-E12 is a robust Allen Bradley Miniature Contactor, part of Allen Bradley’s reputable 140G series focused on efficient mid-load motor management. This Allen Bradley Miniature Contactor is tailored to address the demands of wheat agricultural operations—such as controlling medium-sized grain conveyors, automated irrigation pump motors, or wheat cleaning machine drives—where consistent mid-power delivery is vital to avoid disruptions in wheat harvesting, processing, and storage.

Constructed with high-grade flame-retardant thermoplastic (UL94 V-0 certified) and silver-nickel alloy contacts, the Allen Bradley Miniature Contactor reduces electrical arcing and withstands frequent on/off cycles, even in dusty wheat processing facilities or moderately humid outdoor farm environments. Its 140G-NS0H4-E12-specific design includes a 12V DC dedicated coil (E12 rating) and a compact, modular structure that supports flexible installation. These features enable seamless connection to wheat farm sensors (e.g., grain level detectors, irrigation flow monitors) and simplify setup in compact control cabinets of mobile or fixed agricultural equipment. The space-saving dimensions (approx. 75×45×28mm) make it ideal for both small-scale wheat farms and mid-sized industrial setups where control panel space is limited.

Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor operates reliably in temperatures ranging from -20°C to 70°C and handles up to 85% non-condensing humidity. It delivers a mechanical service life of 3 million operations and an electrical service life of 600,000 operations, ensuring long-term durability across multiple wheat growing seasons while lowering maintenance and replacement costs for farm and industrial operators.
