Square D 9037HG35R Float Switch 575VAC 1HP Open On Rise

The Square D 9037HG35R is a heavy-duty float switch designed for automatic liquid level control in industrial and commercial pump applications. This mechanically-actuated switch operates on 575VAC systems and is rated for 1 horsepower motor loads, providing reliable on/off control for pumps, alarms, and other equipment.

Key Features:

• 575VAC voltage rating for industrial three-phase applications
• 1 HP resistive load capacity for direct motor control
• Open on rise operation - contacts open as liquid level increases
• Rugged mechanical float design for reliable operation in harsh environments
• NEMA rated enclosure protects switch mechanism from moisture and contaminants
• Suitable for water, wastewater, and compatible liquids
• Universal mounting options for tank and sump installations

This float switch is ideal for dewatering applications, sump pump control, lift stations, and industrial process control where dependable liquid level sensing is required. The open-on-rise configuration is commonly used in pump-down applications where the pump should stop when the desired low level is reached.
