SIM-A Single Phase Simplex Sump Pump Control Panel

The SIM-A control panel will alert of a high liquid level and control a 120/208/240V single phase pump in dewatering, sewage and wastewater pumping applications. The simplex panels include integrated electronic control and alarm circuitry, an IEC motor contactor and three floats: pump on, pump off, and high liquid alarm. The controls are housed in a NEMA 4X heavy duty polycarbonate enclosure convenient for field wiring.
