Universal Protection Unit for Electric Motors

UBZ-118

The Universal Single Phase Induction Electric Motor Protection Unit UBZ-118

The Universal Single Phase Induction Electric Motor Protection Unit UBZ-118 is a microprocessor based unit.

 

 

The UBZ-118 unit is designed to provide permanent control of mains voltage parameters and current effective value, which is consumed by the 230V/50Hz motor.

 

 

In the UBZ-118 provides an input for water level sensor for remote start or stop the motor.

 

 

The setting of phase shifting capacitor directly into the device itself.

 

 

UBZ-118 provides protection in the following situations:

 

 

  • when the mains voltage is of poor quality (over & under Voltage);

 

  • mechanical overloads of the motor (over current);

 

  • when motor torque is lost/ dry run (under current);

 

  • delayed start or rotor lock-up;

 

  • thermal overload (heat model of the motor).

 

 

For each separate type of fault, the unit allows to enable or disable an automatic reset (AR) of the motor.
