Automatic protections

Current overload protection

Current overload protection

The CBO control box protects the oil-cooled PSC motor against overload. In case the pump is partially or totally blocked, the amperometric protection in the control box stops the motor to protect it.

Information on a proper installation

  • In order to reset the amperometric protection sensor, it is necessary to press the appropriate button on the CBO.
