Key Features

• Dual-Rated Coil: Operates on both AC (50/60 Hz) and DC voltage (110–127V), enabling global use in diverse control circuits.
• Integrated Auxiliary Contacts: Factory-equipped with 1NO + 1NC side contacts for interlocking, status indication, or control circuit logic, eliminating the need for add-on modules in basic applications.
• High Current Capacity: 192A AC-1 rating supports resistive and inductive loads, while 150HP @ 460V handles large three-phase motors in industrial settings.
• IEC & Global Compliance: Certified to UL, CSA, IEC, and CE standards with dual US/European markings, ensuring compatibility with international electrical codes and facilitating global equipment deployment.
• Robust Construction: Designed for heavy industrial environments with high vibration, dust, and temperature fluctuations; features finger-safe terminals for operator protection.
• Modular Design: Compatible with C-2000 series accessories (overload relays, interlocks, surge suppressors) for customizable motor control solutions.
• Low Coil Power Consumption: Reduces energy waste and heat generation during continuous operation, enhancing system efficiency.

Applications

• Industrial Motor Control: Starting, stopping, and reversing three-phase AC motors (up to 150HP @ 460V) in manufacturing, processing, and material handling equipment.
• HVAC Systems: Controlling large fans, blowers, and compressors in commercial buildings, data centers, and industrial facilities.
• Oil & Gas Industry: Motor control for pumps, compressors, and drilling equipment in harsh, high-vibration environments.
• Marine & Offshore: Power switching and motor control on vessels, platforms, and coastal installations (compliant with marine certification standards).
• Renewable Energy: Integration into wind turbine, solar inverter, and energy storage systems for load switching and grid connection control.
• Transportation: Motor control for conveyor systems, cranes, and heavy machinery in ports, rail yards, and logistics hubs.
• Legacy System Retrofits: Replacement or upgrade of older GE or third-party contactors in existing industrial panels, leveraging its DIN rail mount and standard dimensions for easy integration.

Additional Notes

• The CK09BE311J is part of GE’s C-2000 IEC contactor line, which was widely adopted by OEMs and system integrators for its versatility and global standardization.
• As an obsolete model, it is recommended to consult GE or authorized distributors for modern replacement options (e.g., GE’s CK-E series) for new installations, while spare parts remain available for maintenance of legacy systems.
