Liquid Level Switch for Tank Monitoring

This Square D liquid level switch activates on rising fluid levels in open tanks. The float mechanism closes the circuit when liquid lifts it through 1 1/4 inches of travel. Rated for 10 A at up to 575 V, it suits industrial pump control and alarm circuits.

Suits Automated Pump Control Not Low-Level Cutoff

The close-on-rise function makes it ideal for starting pumps or triggering high-level alarms as tanks fill. It cannot open a circuit on rising liquid, so systems needing low-level shutdown or open-on-rise logic should choose a different switch type.

Open Tank Mount with Aluminium Body

The unit mounts directly on open tanks using its 7.1 inch overall length and stainless steel float assembly. The aluminium body and NEMA 4 rating withstand -22 to 220 degrees F. It frees control panels from separate float wiring by integrating the switch at the tank.

Questions about this item

What tank opening size is needed for the 7.1 in overall length and 7 in float?

The switch mounts on an open tank; allow clearance for the 7.1 in body and 7 in stainless steel float so it can move through its 1 1/4 in travel without hitting walls.

Will the 10 A, 575 V rating handle my existing 240 V single-phase motor?

Yes — at 240 V single-phase the switch is rated for 3 hp, so a 10 A motor at that voltage is within the contact limits.

How can I verify the close-on-rise action after wiring?

Raise the liquid to lift the float; the DPST-2NC contacts should open. Lower the level and they close again, confirming the close-on-rise function.
