Single Phase Simplex Motor Contactor Control

The Model 112 Build-A-Panel™ control panel provides greater flexibility by ordering through options, allowing you to customize a standard panel to your specific needs.

The Model 112 control panel provides a reliable means of controlling one 120/208/240V single phase pump in water and wastewater applications.
