Products Inverter and electric control panel

technical specifications

Control panels for small deep well pumps or booster sets with surface pumps.

Q-BTE control panels are made of plastic or metal boxes with minimum IP55 protection.
Each panel has indicator lights for power on, thermal trip and engine running, a manual or automatic switch, a disconnecting switch with door lock system.
A terminal block allows the connection to the users and to external commands such as pressure switches, floats etc.
