Product Description
The GE CK12BE300 is a heavy-duty, three-pole industrial contactor designed for switching high-power electrical loads. As part of the CK series, this unit features a sophisticated electronic coil interface that allows the contactor to operate reliably on both AC and DC control voltages ranging from 220V to 250V. It is engineered to handle AC3 category loads—specifically squirrel-cage motors—up to 375 kW. Its robust construction ensures high mechanical and electrical durability in the most demanding industrial environments.
Application Areas
- Motor Control: Heavy-duty starting and stopping of large three-phase induction motors.
- Power Distribution: Switching of heating loads, capacitor banks, and lighting systems.
- Heavy Industry: Primary use in steel mills, mining operations, and large-scale manufacturing plants.
- Infrastructure: Power management in water pumping stations and large HVAC chillers.
Product Specifications
- Weight: 11.5 kg
- Dimensions: 275 mm x 210 mm x 220 mm
- Country of Origin: France / Poland
- Mounting: Base plate mounting (Vertical orientation recommended)

Operating Precautions
- Coil Polarity: For DC control applications, ensure correct polarity is observed as specified on the electronic coil terminals.
- Arc Chute Inspection: Before commissioning, verify that the arc chutes are securely seated and free from transit debris.
- Terminal Torque: Given the high current flow, power terminals must be tightened to the manufacturer’s specified torque to prevent overheating and contact welding.
- Maintenance: Regularly inspect the main contacts for pitting or erosion; do not file the contacts, as this removes the specialized silver-alloy coating.
