iDP-210 Feeder Protection Relay

Idea_and_IdeaPlus_Relays.jpg

The iDP-210 is a member of Eaton's Cooper Power™ series Edison™ Idea™ line of protective relays. The iDP-210 is a full-featured relay suitable for a variety of protection applications including feeder protection, reclosing, synch-check, frequency-based load shedding, reverse power, overcurrent, over/under voltage and frequency. The iDP-210 also provides advanced power quality, metering, control, communication and PLC functions.
