GE T35-E00-HUH-F8N-H6C-MXX-PXX-WXX Protective Relay

The GE Multilin T35-E00-HUH-F8N-H6C-MXX-PXX-UXX-WXX, also cataloged as the T35-E00-HUH-F8N-H6C-MXX-PXX-WXX Protective Relay Module, operates as a dedicated hardware component for comprehensive feeder and motor protection within utility and industrial power systems. It processes multi-phase electrical measurements and digital fault sequences natively at the relay tier to maintain trip timing execution parallel to master substation automation network platforms.

Hardware Specifications

Industrial Control & Drive Integration

• Backplane Bus Communication Velocity Licences: Internal processing pipelines manage high-speed event logging and waveform capture without impacting the communication speed of external SCADA networks.
• Profinet / EtherNet/IP Deterministic Networks Mapping: Real-time tripping statuses and analog quantities are mapped directly to deterministic communication interfaces for sub-cycle telemetry coordination.
• I/O Density Scaling: Configurable hardware blocks optimize terminal allocations across compact panel footprints while maintaining isolated signal routing.
• Firmware Flash Compatibility: Secure memory architectures allow verified firmware updates to be deployed across communication ports without compromising core protection logic.

Frequently Asked Questions

Q: What are the primary power-up restrictions for hot-swap operations of this protective relay?

A: Hot-swapping the protection module is restricted while auxiliary control power and live CT/PT circuits are energized, as open-circuit current transformer hazards can occur.

Q: How does the unit manage internal power supply variations during grid voltage sags?

A: The internal power supply unit regulates nominal 125 V DC or 120/240 V AC inputs to maintain uninterrupted trip execution during transient grid disturbances.

Field Installation Guidelines

• Mechanical Mounting: Secure the chassis firmly into standard 19-inch rack structures or panel cutouts using appropriate mounting hardware to withstand seismic and operational vibrations.
• Shielded Grounding: Terminate all RS485 communication cable shields and protective earth conductors directly to the designated sub-station grounding stud to prevent electromagnetic interference.
• Terminal Torque Specification: Fasten all current and voltage terminal screws using calibrated torque drivers to standard industrial ratings to ensure low-resistance paths under high fault currents.
