GE Multilin C60-K03-HKH-F8L-H67-M67-P6C-U6D-W6D Breaker Protection System

Description

The GE Multilin C60-K03-HKH-F8L-H67-M67-P6C-U6D-W6D is a substation-hardened protection, control, and monitoring unit designed for circuit breaker management in substation and industrial automation applications. It supports complex dual-breaker busbar configurations—such as breaker-and-a-half or ring bus schemes—and provides integrated protection functions, including breaker failure detection, multi-shot autoreclosing, synchrocheck, overcurrent, overvoltage, and sensitive directional power elements.

Equipped with high-density I/O configurations, advanced time synchronization, and robust communication protocol support (such as IEC 61850, DNP 3.0, Modbus TCP/IP, and IEC 60870-5-104), the GE Multilin C60K03HKHF8LH67M67P6CU6DW6D enables deterministic control logic execution and real-time visualization via an integrated color HMI panel.

Features

• Integrated Breaker Management: Complete protection, control, and monitoring in a unified modular platform.
• Dual-Breaker Support: Native functionality for breaker-and-a-half and ring bus arrangements with internal summation of up to 4 CT sets.
• FlexLogic Engine: High-speed programmable logic engine supporting up to 1024 lines of custom control schemes.
• Advanced Protection Elements: Includes breaker failure, 10-element synchrocheck, multi-shot autoreclosure, overvoltage, directional power, and thermal overload features.
• High-Density I/O Flexibility: Scalable hardware architecture with selectable digital I/O options to support wide switchyard automation needs.
• Comprehensive Disturbance Recording: Advanced event recorder (1024 events), COMTRADE oscillography (up to 64 digital / 40 analog channels), fault summary reporting, and data logging capabilities.
• Substation Communication: Features advanced Ethernet options with support for IEC 61850 Ed. 1/Ed. 2, PRP (IEC 62439-3), Routable GOOSE, IEEE 1588 time synchronization, and CyberSentry security.
• Human-Machine Interface: Graphical front panel display with user-programmable pushbuttons, status LEDs, and bay display options.

Applications

Installation Guidelines

• Rack Mounting: Install horizontally into a standard 19-inch rack enclosure. Ensure proper ventilation and clearance around the chassis to allow heat dissipation.
• Grounding: Connect the protective grounding lug directly to the main substation ground bus using low-impedance ground straps to minimize EMI/RFI noise interference.
• Power Supply Wiring: Verify the control power supply matches the 125/250 V AC/DC nominal operating voltage before energizing the module. Ensure proper fusing on incoming power lines.
• CT/VT Connections: Ensure correct polarity and phase orientation when wiring current transformer and voltage transformer inputs. Never open-circuit energized CT secondary circuits.
• Fiber-Optic Cables: Maintain recommended bend radii for ST fiber-optic Ethernet connections to prevent signal attenuation or physical fiber damage.
