Allen Bradley 109-C09AA-OLR-3-4G Overload-Protected Miniature Contactor

Built-In OLR: Eliminates separate overload relays, simplifying setup and preventing motor burnout from load spikes.

Low-Voltage Flexibility: 24-230V AC range adapts to unstable rural wheat farm grids, avoiding unexpected shutdowns.

Durable Silver Contacts: Resist arc erosion during frequent harvest-season start-stops, reducing maintenance.

Compact Design: 72×48×40mm size fits tight control cabinets of portable wheat machinery (e.g., mobile irrigation pumps).

Dust Resistance (IP10): Shields against wheat dust and grain debris, suitable for barns and processing areas.

Global Compliance: Meets IEC/UL standards, ideal for international wheat farm or light-industrial projects.

Wheat Farm Irrigation Pumps: OLR prevents motor burnout if the pump intake clogs with debris, adapting to rural voltage shifts.

Grain Conveyors: Automatically cuts power if wheat clogs the conveyor, protecting the motor while IP10 resists grain dust.

Small Flour Mill Auxiliaries: Shields auxiliary motors (e.g., for sifters) from overloads caused by uneven flour flow, ensuring continuous milling.

Wheat Seeders: Compact size fits seeder control panels, OLR safeguards the motor during variable soil-resistance planting.

Light Industrial Fans: Controls fan motors in wheat storage barns, OLR prevents overheating from dust buildup on fan blades.

Grain Dryers: Protects dryer motors from overloads when drying wet wheat batches, ensuring consistent heat and preventing motor damage.
