1 / 1 page Protection Relays & Controls © 2014 Littelfuse Protection Relays & Controls FPU-32 SERIES (PGR-7200) Feeder Protection Unit Description 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.
