Automatic protections

Current overload protection

Current overload protection

The ZDS Control Box protects the P.O3 complete pump against overload. In case the pump is partially or totally blocked, the overload protection in the ZDS Control Box stops the pump to protect it.

Information on a proper installation

  • If you are using a generator with an internal combustion engine, it is necessary that the generator’ s power measured in kW (in continuous delivery) is three times the rated power in kW of the submersible pump.
  • We recommend to install a proper cooling jacket in installations bigger than 10 cm, to guarantee the correct motor cooling flow.
  • In order to reset the overload protection sensor, it is necessary to press the appropriate button on the CBO.
