Schneider Electric 9038-CG32 Closed Tank Float Switch

Schneider Electric’s Square D 9038-CG32 Closed Tank Float Switch is a DPST, closed-tank level switch designed to monitor liquid height inside a tank and close two independent circuits on rising liquid. It offers side-mount installation, a 2-1/2 in MNPT tank connection, and a float travel of 6.5 in, with a 2-pole, 4NO contact configuration for dual-circuit control. The unit is constructed from painted cold-rolled steel and shipped in a NEMA 1 enclosure, with UL and CSA approvals for industrial environments. Electrical ratings cover 230 VAC 1-phase, 575 VAC 3-phase, and 230 VDC, enabling integration with pumps, alarms, or interlock circuits in closed-tank applications. As part of the Class 9038 family (Type C mechanical alternator, closed-tank design), the CG32 model provides reliable liquid-level sensing for fluids such as water and hydraulic oils inside enclosed tanks.
