GINRI Electronic Overload Relay Digital Motor Protection Relay Over Current Over Voltage Protection Device

 

The advantage for the Digital motor protection relay

 

Motor protectors have evolved from the past mechanical to electronic and intelligent, with high sensitivity, high reliability, many functions and convenient debugging. The current, voltage, temperature and other parameters of the motor can be directly displayed, and the type of fault after the protection action is clear at a glance, which greatly facilitates the judgment of the fault, and is beneficial to the fault handling at the production site and shortening the recovery production time.

 

In addition, according to the motor air gap magnetic field, the motor eccentricity detection technology makes the motor wear state online monitoring possible. The curve shows the change trend of the value reflecting the eccentricity of the motor, and records the change of the value in two years, which can find the bearing fault early.

 

Features


1. Separate structure, LED part panel mounted and CT part screw fixing

2. Built-in LED and keypad afford a precise,digital setting

3. Three-phase monitoring of short-circuit, locked-rotor,overcurrent, undervurrent, phase loss, phase unbalance,overvoltage,undervoltage

4. Powered by the measuring circuit

5. Earth fault (should couple with ZCT)

6. Fault recording

7. RS-485 communication port (optional)

8. 4-20 mA analog output (optional)

9. 2 C/O output contacts, one for trip,one for alert
