EATON FP5000-00 / FP5200-00 (66D2041G11) Generator Protection Relay

Overview

The EATON FP5000-00 and FP5200-00, referenced with part number 66D2041G11, are microprocessor-based generator protection relays from Eaton's Cutler-Hammer division. These advanced devices are designed specifically for industrial synchronous generators, providing comprehensive protection, metering, and control functions in a single integrated unit. They replace multiple discrete relays and meters, simplifying panel design and improving reliability.

Key Features

• Comprehensive generator protection including overcurrent, over/under voltage, over/under frequency, reverse power, and loss of excitation

• Microprocessor-based design with accurate digital processing and programmable setpoints

• Integrated metering for voltage, current, power, frequency, and power factor

• Multiple communication options for integration with plant SCADA systems

• Event recording and oscillography for post-event analysis

• Compact design suitable for retrofit into existing switchgear

• Programmable logic for customized protection schemes

Technical Specifications

• Protection Functions: 50/51, 27/59, 81O/U, 32, 40, 46, 47, 51V, 87

• Input Power: 120-240 VAC/VDC control power

• Current Inputs: 5A or 1A nominal CT secondaries

• Voltage Inputs: Up to 600VAC direct connection

• Communication: RS485 Modbus, optional Ethernet or PROFIBUS

• Display: Backlit LCD with local pushbutton programming

• Mounting: Draw-out case or panel mount options

Applications

The FP5000/FP5200 series is ideal for industrial power generation applications including cogeneration plants, emergency standby generators, prime power installations, and distributed generation sites. They protect generators from electrical faults and abnormal operating conditions that could cause damage or reduce service life. The relays are suitable for both new installations and retrofits of older electromechanical protection systems.

Programming and Configuration

Setpoints and logic are configurable via the front panel interface or through Eaton's protection software. Multiple setting groups allow adaptation to different operating modes or seasonal variations. Password protection prevents unauthorized changes to critical protection parameters.

Certifications and Compliance

The FP5000/FP5200 relays are designed and tested to meet applicable ANSI/IEEE, IEC, and UL standards for protective relays. They are suitable for use in industrial and utility power systems requiring reliable generator protection.
