Technical characteristics
The QST 1000 control panel is a reinforced version of the classic Pedrollo control cabinets, designed specifically for three-phase submersible pumps up to 7.5 kW that operate in demanding and unstable conditions. Unlike standard models, the QST series is equipped with level sensors that provide reliable dry-run protection even when the water level in the well drops sharply.
The housing is made of self-extinguishing thermoplastic with a high degree of protection against moisture and dust. The panel monitors load current, protects the pump from overload, short circuit, emergency modes, and ensures stable start-up and safe motor shutdown.
