Eaton Corporation Recently Announced MP-4000, A Multi-Function Motor Protection Relay
CLEVELAND … Diversified industrial manufacturer Eaton Corporation recently announced the availability of its Cutler-Hammer® MP-4000 motor protection relay. The multi-function motor protector combines all the features required to ensure protection, fault diagnostics, power metering and communication versatility in one unique, cost effective package.
The MP-4000 expands upon industry-leading protection, control and diagnostics found in the MP-3000 by adding voltage inputs from Voltage Transformers (V.T.). The V.T. inputs enable additional protection functions and metering such as under/over voltage, negative sequence voltage, power factor and frequency. Other upgraded features include new metering capabilities and new communication options like Modbus RTU and Device Net. Reliable construction, flexible features and user-friendly operation make the MP-4000 an industry-leader in motor protection relays.
"The MP-4000 combines multiple metering and relaying functions into one user-friendly device while its automatic set-up feature dramatically decreases programming time,” said Bill Vanlandingham, power distribution and control assemblies business unit manager, Eaton Corporation. “Capital optimization, operating cost efficiency, reduced installation and maintenance requirements, and greater reliability are primary drivers for most enterprises. The MP-4000's features directly address our customer needs, while continuing Eaton’s legacy of leadership through innovation."
As well as the features mentioned above, the MP-4000 offers a number of additional features:
• The Intel-I-Trip, an algorithm created by Eaton to develop customer trip curves for both maximum protection and capacity utilization of the motor.
• Provides the industry-leading voltage sag ride-through at 20 cycles and can easily withstand most power quality events.
• Offers complete metering and protection functions in accordance with the IEEE.
• Conforms to the United Laboratories (UL) 1053 ground fault protection standard, thereby eliminating the need for a separate ground relay – saving wiring, space, time and money.
• Motor Start Profile provides start logic control to protect the motor against excessive starts or starting the motor before it has sufficiently cooled for both line starters and reduced voltage starters.
The MP-4000 allows for future planning because of its advanced event logging and activity monitoring systems. The relay’s event log provides motor operating records for the twenty most recent trips or alarm events, the one hundred most recent motor events, and the last four starts with accurate time and date stamping.
To ensure the motor is running efficiently, the MP-4000 provides information on how to get it back on-line as soon as possible in the event of a trip. Eaton’s Power Xpert® Server Core Software turns simple data into valuable information, allowing for informed operating and predictive maintenance decisions, troubleshooting and increased reliability and uptime.
Power Xpert Architecture is a further development of Eaton’s PowerChain™ Management solutions, which help enterprises proactively manage their power system as a strategic, integrated asset. Power Xpert Architecture lets you decide how much of your power system you want to integrate, as well as the appropriate integration method.
