Schneider Electric PC-301 Pressure Switch

Schneider Electric PC-301 Pressure Switch delivers precise control for air and non-combustible gas systems. This model features an adjustable differential and a diaphragm-based operator, ensuring reliable response and repeatable set points in HVAC and industrial panels.

Operating pressure is 12 Inch WC, with a differential range of 0.04 to 0.1 Inch WC (set point). The unit handles air and non-combustible gas media and uses an SPDT 2-circuit contact configuration for versatile control. It supports multiple voltages (up to 277 VAC) with full-load and locked-rotor ratings, and comes in a rugged NEMA 1 metal enclosure with coded screw terminals for secure wiring. UL and CSA approvals ensure safety and reliability in commercial installations.

Compact, robust construction supports easy installation in control panels or HVAC equipment. The PC-301 tolerates temperatures from 35 to 140 deg F and measures 4-3/4 inches wide by 4-3/8 inches deep by 5-1/8 inches high, making it a versatile choice for space-constrained applications.
