1. Product Name
Allen Bradley 109-C09AD-OLR-901 Low-Voltage Miniature Contactor with Overload Protection
2. Product Introduction
The Allen Bradley 109-C09AD-OLR-901 is a compact Allen Bradley Miniature Contactor integrated with overload protection, designed for low-voltage motor control in wheat farms and light industry, preventing motor damage from overcurrent.
3. Product Description
The Allen Bradley 109-C09AD-OLR-901 is a high-reliability low-voltage Allen Bradley Miniature Contactor, part of Allen Bradley’s 109 series tailored to address wheat agricultural and light industrial motor control pain points—especially the risk of motor burnout from overloads during peak operations like harvest. This Allen Bradley Miniature Contactor stands out by integrating built-in overload protection (OLR), eliminating the need for separate relay components and simplifying control panel design.
With a space-saving footprint of ~78×52×45mm, this Allen Bradley Miniature Contactor fits seamlessly into compact control panels of portable wheat farm equipment, such as mobile grain cleaners or small irrigation pumps, where installation space is limited. It operates on a flexible 24-240V AC voltage range, adapting to unstable rural power grids common in wheat-growing regions and avoiding unexpected shutdowns during critical irrigation or grain processing cycles. The contactor uses silver-tin oxide contacts for enhanced arc resistance and durability, supporting continuous 8-hour runs—essential for wheat harvest season—and features an IP10 protection rating to shield internal parts from wheat dust and chaff, a leading cause of contactor malfunctions in farm environments.
Compliant with IEC 60947-4-1 and UL 508 safety standards, this Allen Bradley Miniature Contactor delivers a mechanical service life of 8 million operations and an electrical life of 900,000 operations, enough to endure 7-9 wheat harvest cycles. Its color-coded wiring terminals simplify installation for farm technicians, reducing wiring errors that could disrupt motor function, while the overload protection triggers automatically at 1.2× rated current to safeguard motors.

5. Product Advantages

  • Built-In Overload Protection: Automatically cuts power at overcurrent, preventing wheat farm motor burnout during peak use.

  • Wide Voltage Adaptability: 24-240V AC range works with unstable rural grids, avoiding harvest/irrigation downtime.

  • Dust-Resistant (IP10): Shields against wheat dust/chaff, reducing malfunctions in barns/field setups.

  • Durable Contacts: Silver-tin oxide construction resists arcing, supporting long continuous operation.

  • Space-Saving Design: ~78×52×45mm size fits portable wheat equipment with narrow control panels.

  • Easy Installation: Color-coded terminals simplify wiring for non-specialized farm staff, cutting setup time.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms its focus on wheat-centric agricultural automation, offering integrated solutions for small-to-mid-sized wheat farms, local grain cooperatives, and small flour mills. The business likely packages hardware like the Allen Bradley 109-C09AD-OLR-901 into “farm-ready motor control kits”—e.g., “irrigation pump protection kits” or “grain cleaner control packages”—pre-configured for common wheat farm motor ratings (0.5-1.5kW) to eliminate complex setup.
This Allen Bradley Miniature Contactor aligns with the site’s value proposition: its built-in overload protection addresses a key farm pain point (motor replacement costs from overloads), while the IP10 rating and wide voltage range suit rural conditions. www.wheat-auto.com may also provide farm-specific after-sales support—such as overload threshold adjustment guides and dust-cleaning tutorials—to help non-technical staff maintain equipment. By integrating this contactor, the site bridges industrial reliability with agricultural practicality, making automation accessible for small-scale wheat operations.
7. Application Scenarios
The Allen Bradley 109-C09AD-OLR-901, as a protected Allen Bradley Miniature Contactor, excels in wheat farm and light-industrial motor control:

  • Wheat Irrigation Pumps: Protects 0.5-1.5kW pumps from overload due to clogs, avoiding costly motor replacements.

  • Mobile Grain Cleaners: Fits compact panels, IP10 dust resistance + overload protection ensures field-side reliability.

  • Grain Sieve Motors: Shields sieve motors from overload during heavy grain flow, maintaining harvest efficiency.

  • Small Flour Mills: Controls mini mixer motors, overload protection prevents burnout from dough blockages.

  • Wheat Drying Fans: Safeguards fan motors from overheating in enclosed drying barns, ensuring consistent drying.

  • Portable Seeders: Works with on-board generators, wide voltage range + overload protection adapts to remote field use.
