Product Description

 

 

 

PR260 electric motor relay is an all-in-one solution designed to continuously monitor 3-phase power lines for abnormal conditions. The motor differential protection three phases can be used with motors of any size or type.

 

When the PR260 motor protection relay feeder protection relay senses the motor runs into the preset abnormal alarm value, the PR265 intelligent electric motor protection relay will automatically trigger the release switch to shut down the circuit. Option RS485 communication port can upload the monitor data and alarm status to the remote control system.

 

Feature

* Low-cost electronic design relays, can replace a variety of single-function protection relays.

* Suit for Motor under 0.66KV.

* Build in 3P CT for current sampling, suit for current under 200A.

* 2 digital outputs for external control loops.

* Optional RS-485 network communications.

* Optional earth leakage sensor or analog output.
