The FPU-32 Feeder Protection Unit provides integrated protection, metering, and data-logging functions. It is an excellent choice for retrofitting and upgrading older relays because of its compact size and ability to use existing CTs. The FPU-32 is used to protect distribution feeders in processing, manufacturing, petroleum, chemical, and wastewater treatment facilities.

A large oil & gas exploration company made what is expected to be one of the biggest oil and gas discoveries of the decade in the Permian region’s western part of Texas. The company began evaluating several brands of protection relays to protect their investments in pumps and motors, optimise productivity, and improve safety. After the company’s engineers tried the Littelfuse Bluetooth® Overload Relay MP8000, the search was over.

Fuseco has strong relationships with many clients from a wide range of industries.
The MP8000 has a wide voltage and current range and operates on 50/60 Hz to protect any motor or pump.
It can also be used to retrofit older current-only based electronic overloads.
It can operate between 90-690VAC and 0.5-1,000A.
-40oC to 70oC
Traditional relays require the user to open the electrical cabinets (where relays are typically installed) panel door to use the relay, whether it’s to modify the settings, or to review the cause of a trip event.
Opening the panel door exposes the worker to shock hazards. Bluetooth, however, enables remote access to these settings, metering and data log information which prevents personnel from unnecessarily having to open the door, thus less exposure to risks.
The MP8000 can be used in both single phase and 3 phase applications.
Yes, the MP8000 can be put into current-only mode which will disable voltage-based protection functions. However, Littelfuse strongly recommends utilizing the voltage-based protection functions for superior protection especially prior to motor startup.
The current-only mode is intended for retrofit applications on voltages above 690 VAC.
The MP8000 can be surface or panel mounted, or installed on a DIN rail.
No, the MP8000 uses Bluetooth to connect to your smart phone or tablet via the Littelfuse app, This enhances the users safety as it allows remote access.
Yes, you can access the information remotely through the Littelfuse MP8000 PC software or through other software programs communicating with the MP8000 through the Ethernet interface. Contact Fuseco for information on how to download this software.
