Industrial Liquid Level Switch
The Square D 9038AG1N4 is a float-operated liquid level switch designed for open tank mounting in industrial environments. It uses a stainless steel float to detect rising liquid levels and closes its contacts automatically when the level increases. The unit operates reliably across a wide temperature range from -22 to 220 degrees Fahrenheit.
Replaces Basic Float Switches
This model upgrades from simpler switches by offering a DPST-4NC contact form with a 460V AC VA rating and a 10 A current capacity. The jump is worth it for applications requiring higher horsepower control, supporting up to 2 hp at 120V single-phase, 3 hp at 240V single-phase, and 5 hp at 240V three-phase. It handles motor loads directly without an external contactor in many setups.
Limited to Open Tank Mounting
The switch is constrained by its NEMA 1 rating and open tank mounting style, making it unsuitable for sealed, pressurised or hazardous location tanks. Float travel is fixed at 1 1/4 inches, so it cannot accommodate applications needing adjustable differential or longer actuation ranges. The steel body and 10.32 inch overall length require sufficient vertical clearance above the tank.

Questions about this item
What tank opening and clearance does the 10.32 in overall length and 7 in float diameter require?
The switch needs an open tank mounting with enough vertical space for the 10.32 in body and horizontal clearance for the 7 in diameter float to travel its 1 1/4 in range without obstruction.
How is the DPST-4NC contact block wired for the close-on-rise function, and which step is often missed?
Wire the four normally closed contacts so the circuit completes when the float rises; the step often missed is confirming the 460V AC VA rating matches the control voltage before energising.
Which components should be inspected periodically given the -22 to 220 °F operating range and stainless steel float?
Inspect the stainless steel float for corrosion or build-up, verify the steel body seals remain intact, and test the DPST-4NC contacts for reliable closure at the 10 A rating after temperature cycling.
