The motor is protected by connecting the thermistors (TP) built into the motor.
If the TP's respond to too high winding temperature, a relay switches and switches off the motor via a contactor. The device has an electronic switch on lock (can be switched off) to prevent undesirable restarting of the motor. A reset button is installed. Integrated LEDs show the operating state.
Explosion-protected operating equipment in areas with a gas explosion risk (identification G: Gas) or in areas with inflammable dust (identification D: Dust) can be protected.
The motor protection unit U-EK230E is certified according to ATEX Directive 94/9/EC.
Note: Mounting of the motor protection unit outside the EX area
