FP-4000 Product Description

• Microprocessor-based protection with monitoring and control for

medium voltage main and feeder breakers.

• Current, voltage and frequency protection for electric power

distribution systems.

• Complete metering of voltage, currents, power, energy,

minimum/maximum and demand functions.

• Programmable logic control functions for main-tie-main

transfer schemes.

• Trip logs, event logs and waveform capture for better fault analysis

and system restoration.

• Data Logger to provide energy usage profiles for better planning,

utilization and energy usage.

• Fixed case design.

• Meets ANSI and UL standards.

When the FP-4000 isn’t responding to disturbances in the power

system, it’s providing valuable metering information at the relay and

remotely. It provides energy usage and demand reading, and can

alarm when usage reaches a set value. Power factor measurements

can be used for cap bank switching to control kvar demand.

Onboard data trending can provide load profiles for up to 40 days.

The protection functions are listed below and shown in Figure 1.

The FP-4000 provides phase overcurrent:

• Two-stage instantaneous with timers (50P-1 and 50P-2).

• Inverse time overcurrent (51P-1).

• 10 standard curves.

• Instantaneous or time delay reset.
