Control Panell QET 300 (2.2 kWt)

The QET 300 control panel is designed for operating three-phase submersible electric pumps with a power rating of up to 2.2 kW. It ensures correct motor start-up, monitors operating conditions, and protects the equipment from emergency situations.

The QET 300 model is a reliable solution for water supply systems where operating conditions meet the required parameters: stable voltage, high water level in the well, and no risk of dry running.

Operating conditions

The QET 300 control panel is recommended when:

▪️ the well has a high water yield,
