Schneider Electric Square D 9037HG32 Float Switch

Schneider Electric Square D 9037HG32 Float Switch is a Pumptrol‑style liquid‑level control used to automatically start and stop a pump based on tank level, configured with a left‑float orientation and a two‑pole, two normally open (DPST, 2NO) contact set. It is built for rugged indoor service with a NEMA 1 enclosure, UL and CSA listings, and a polypropylene body designed for chemical resistance in typical pump installations. The device accepts a broad voltage range of 120–600 VAC and 125/250 VDC, with a common rating of up to 575 VAC and 2 HP on single‑phase service; its compact form measures about 2.58 in. in diameter and 7.13 in. long, and it uses a float rod/float mechanism to actuate the switch. The operating temperature range is −22 to 220 °F, enabling it to function across a wide variety of liquid applications while maintaining reliable level control.
