Product Description

Product Description

PR201 motor protector is an all-in-one solution designed to continuously monitor 3-phase power lines for abnormal conditions. The digital motor protection relay can use with motors of any size or type.

When the PR201 motor protection relay sense the motor runs into the preset abnormal alarm value, PR201 phase-failure 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 remote control system.

Features

* Low cost electronic design relay, 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
