Electronic Motor Overload Relay Digital Over Current Voltage Protection Device

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.
