SCHNEIDER EASERGY P3U30 PROTECTION ELECTRIC RELAY

Schneider Easergy P3U30 Relay is a complete protection relay for medium voltage applications, including feeder, motor, transformer, and generator protection. It embeds all the latest communication protocols on serial or Ethernet links. Based on more than 100 years of experience in network protection relays, Easergy P3 benefits from the reliability of Sepam, MiCOM and Vamp.

Easergy P3 protection relay is based on proven technology concepts and developed in close cooperation with customers, so it?s built to meet your toughest demands. It?s available in two sizes to best fit your needs:

The Easergy P3 Standard combines protection functions such as directional earth fault for feeder and motor protection in a one-box solution.
The Easergy P3 Advanced features a modular design that allows user-defined conventional protection and arc flash protection solutions in both new and existing power distribution systems.

Easergy products are designed to be user friendly, a feature that is proven in our customer reports day after day. You will benefit from features that include:

A complete set of protection functions, related to the application
Arc detection (Easergy P3 Advanced)
Dedicated circuit breaker control with single-line diagram, push buttons,
programmable function key and LEDs, and a customizable alarm
Multilingual HMI for customized messaging
