Square D 9038AW1 Float Switch Nema 4 Dpst-db

Product Description

The SQUARE D 9038AW1 is a liquid level float switch designed for pump and tank control applications in industrial and commercial installations. It uses a DPST-DB (double-pole, single-throw, direct-break) contact form and a Line-Load-Load-Line terminal configuration, making it suitable for direct control of motor starters, contactors, or pump circuits. The enclosure carries a NEMA 4 rating, providing protection against windblown dust and rain, splashing water, and hose-directed water. Licensed electricians and industrial maintenance technicians are the primary installers of this device.

This float switch is used in applications where liquid level control is required, such as sump pump systems, lift stations, cooling towers, water storage tanks, and industrial process vessels. The NEMA 4 enclosure rating makes it appropriate for both indoor and outdoor installations where exposure to water or washdown conditions is a factor. It is commonly wired into pump start-stop circuits where level-based automatic switching is needed to protect equipment or maintain process set points.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all power to the circuit before wiring or servicing this switch. Verify that the supply voltage and current load are within the rated parameters of the switch before energizing. Mount the enclosure securely and ensure all conduit entries are properly sealed to maintain the NEMA 4 integrity of the installation.
