1. Product Name
Allen Bradley 105-C12AA-OLR-3-4RW-6P 3-Phase Miniature Contactor with Overload Protection
2. Product Introduction
The Allen Bradley 105-C12AA-OLR-3-4RW-6P is an Allen Bradley Miniature Contactor with built-in overload protection, designed for 3-phase motor control in wheat farms and industrial settings, ensuring safe operation against current spikes.
3. Product Description
The Allen Bradley 105-C12AA-OLR-3-4RW-6P is a high-reliability Allen Bradley Miniature Contactor, part of Allen Bradley’s 105 series focused on 3-phase low-voltage motor safety and control. This Allen Bradley Miniature Contactor addresses a critical pain point in wheat farm and industrial operations: protecting 3-phase motors from burnout caused by variable loads (e.g., uneven grain distribution in conveyors, fluctuating water pressure in irrigation pumps).
With a compact footprint (approx. 78×52×40mm), this Allen Bradley Miniature Contactor fits seamlessly into narrow control cabinets of wheat farm machinery and industrial equipment, avoiding space conflicts with other components. It is optimized for 3-phase power systems—common in heavy-duty agricultural and industrial motors—while the integrated overload relay (OLR) continuously monitors motor current. If current exceeds safe limits, the OLR automatically disconnects power, preventing irreversible motor damage. The contactor uses high-conductivity copper-tin alloy contacts, reducing electrical resistance and arc erosion during frequent motor start-stop cycles, which is essential for wheat harvesting and processing seasons where equipment runs intermittently. Its IP10 protection rating shields internal parts from large debris, suitable for relatively clean wheat processing facilities and standard industrial workshops.
Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor meets global safety benchmarks. It handles motors up to 3.7kW at 400V AC, ideal for 3-phase equipment like wheat farm irrigation pumps and industrial small compressors. With a mechanical service life of 12 million operations and an electrical life of 1.2 million operations, it delivers long-term reliability, minimizing maintenance downtime during peak wheat farming periods.
