This control panel will power one shaft aerator. There is no timer to operate the aerator in this control. The aerator in this system will run continuously. There is no pump control in this control. This is a shaft aerator control with alarm only.
The 7 Amp aerator circuit breaker will supply a 120VAC single phase shaft aerator. The 10 Amp alarm circuit breaker will power the alarm circuit. This control uses a current switch to monitor aerator operation. The shaft aerators do not have air lines and rely on a spinning tee on the bottom of the motor shaft to draw air through the hollow motor shaft and out the tee. If the motor is disconnected from the power source, shuts off due to thermal overload, or the circuit breaker trips, the current switch will activate the alarm light and buzzer. This type of alarm is beneficial over just relying on the circuit breaker to trip which is found in most alarm systems on the market today. There are alarm test and buzzer silence switches mounted in the door of the enclosure.
The enclosure has a NEMA rating of 4X which provides protection from falling dirt, falling liquids, hose-directed water and corrosive agents.
The 10” x 8” x 4” enclosure is made of Polycarbonate and has a hinged lockable door with latches and included screws to secure the door if required. All electrical components are mounted inside the enclosure on an aluminium back plate.
